Part 124

Radial cross vein: (Comst.), is that which divides cell, radius 1.

Radial sector: in general, the lower of the two primary divisions of the radius (Comst.): in Odonata, an indirect branch from the media, just below and parallel with media 2.

Radial vein: in Homoptera, the first important vein next the costa between it and ulnar: in Orthoptera, = radius (Comst.): in Diptera, = 2d longitudinal vein (Meigen), = radius 2 (Comst.).

Radiate veins: the longitudinal veins spreading fan-like in the anal field of secondaries: = anal veins; q.v.

Radiated: marked with lines proceeding from a common centre.

Radicle or Radicula: that joint of the antenna that is articulated to the head.

Radio-medial cross vein: connects the radial and medial systems and usually closes the radial cell (Comst.).

Radius: (Comst.); the third of the longitudinal veins starting from base and dividing into not more than five branches before reaching the margin: the branches are numbered 1, 2, 3, 4, and 5, respectively, beginning at the costal margin and extending outward and downward.

Radix: base of wings, and their point of insertion; see pteropega.

Rami -us: branches: a branch.

Ramification: the branching out in every direction.

Ramify: to branch out in every direction.

Rammel-kammer: = copulation chamber; q.v.

Ramose -ous: branched, or having long branches.

Rapacious: predatory; capturing and eating prey.

Raptatory: = raptorial; q.v.

Raptoria: applied to that series of Orthoptera, in which the anterior legs are fitted for grasping; Mantidae {Scanner's comment: No longer Orthoptera, but Mantodea, a suborder of the Dictyoptera.}

Raptorial: formed for seizing prey.

Rare: seldom seen or found.

Rasorial: formed for scratching; applied to leg structures.

Ravenous: greedy; voracious; hungrily.

Receptaculum seminis: a sac or pouch-like appendage at the junction of the oviducts with the vagina; it is filled during copulation and the eggs are fertilized from it as they are extruded.

Reclinate: directed backward; e.g. the bristles in Diptera.

Reclinatus: = reflexed; q.v.

Reclivate: curved into a convex, then into a concave line.

Recondite: the sting when concealed in the abdomen.

Rectal cauda: the terminal, tubular process or tail terminating the abdomen of some male Hemiptera.

Rectal glands: appendages to or thickenings of the rectum secreting a lubricating material.
