fj-ontal sutures. The frons is sub triangular, rounded at anterior angles, and slightly 

 emarginate for antennae; its front margin is the epistoma. There are three pairs of 

 large setae on the frons, the posterior pair being located rather close together and near 

 the apex of the triangle. The second pair are farther apart and halfway to the front. 

 The anterior pair are located near the lateral angles just behind the antennae. A tiny 

 pair of setae are located just in front of the posterior pair of large setae. A tiny pair 

 are located slightly behind and outside of the median pair of large setae. The median 

 line of the frons is impressed from the posterior angle almost to the middle. 



The epicranial areas are the two large areas on each side of the epicranial suture 

 further bounded by the frontal suture, the pleurostoma, and the hypostoma. The 

 following setae occur on each lobe of the epicranium: One opposite the apex of the 

 frons, one on tlie disk of the epicranium in the line with the preceding; one opposite 

 the middle of the frons and near the frontal suture; one near the hypostoma toward 

 the base of the mandible; one as close to the hypostoma and opposite the base of the 

 maxilla; one near the pleurostoma; the last three forming a triangle. Forming a 

 semicircular line with the setse opposite the frons are a tiny seta, a longer one opposite 

 the antenna, and a long one opposite the pleurostomal seta. 



The antenna is a small, fleshy, two-jointed appendage at the angle of the frontal 

 suture and pleurostoma. The mandibles are bluntly bidentate and have two small 

 setae. The clypeus is attached in front of the frons and is broadly transverse. It 

 bears on the epistomal margin four tiny hairs. The labrum is not as broad; it has a 

 pair of median setae and three pairs of marginal setae. The maxillae attached at the 

 side of the mandibles are terminated by a two-jointed palpus and a setose lacinia. 

 The maxillae are provided with three setae, two near the palpi and one toward the base. 

 The stipes labii is appendiculate, bilobed, bearing two-jointed palpi and a single pair 

 of posterior setae. Each lobe of the mentum is provided with one seta. The thoracic 

 segments are simple, being composed of only praescutum and scutoscutellum. In 

 the prothorax there is no separation of these parts, but they are indicated by the 

 arrangement of the setae. The abdominal segments are dorsally composed of four 

 single sclerites, namely, praescutum, scutum, scutellum, and postscutellum. 



The thoracic spiracle is located on a lobe of the meso thorax, very close to the head. 

 The abdominal spiracles are located on a small lobe at the side of the scutum on the 

 first eight segments. The ninth and tenth abdominal segments are smaller and 

 considerably modified. 



Setae are arranged as follows : Four pairs of tiny hairs on anterior margin of pro- 

 thoracic praescutal area; a row of longer hairs on the scutal area of the prothorax; 

 each segment from the mesothorax back with two pairs of long lateral setae, near 

 which are located smaller and inconspicuous setae; each praescutum with a single 

 pair of setae; on each segment of the abdomen the lateral lobe of the scutellum is 

 provided with a tiny seta, behind and close to the spiracle; each epipleural lobe 

 below the spiracle with two setse; each coxal lobe with several setas which are more 

 conspicuous on the prothorax. 



Pupa (PI. 33, A-D). — Length 4 mm., white. This is a normal, characteristic 

 ciu-culionid pupa with geniculate antennae and legs turned posteriad. Head oval, 

 beak short. The head bears four pairs of basal setigerous tubercles, two pairs of 

 interocular tubercles, and one pair of tiny setae at base of beak. Prothorax with 

 two pairs of antero-marginal setigerous tubercles; one pair of antero-lateral and one 

 pair of postero-lateral setigerous tubercles; four pairs of dorsal tubercles and one 

 pair of ventral. The femora are apically armed with two setae. Mesonotum and 

 metanotum each provided with two pairs of setae. Each abdominal segment bears 

 four dorsal and one or more lateral setae. The ninth segment is armed with two very 

 large processes. The tenth segment is very small and located on the venter of the 

 ninth.
