and scutellum. Between the pro- and mesothorax is an inter- 

 segmental piece Fig. 2, i) which bears the mesothoracic stig- 

 mata (Fig. 2,st). The metathoracic stigmata are closed. The 

 mesonotum and metanotum are each divided into a prescutiim, 

 scutum, scutellum and post-scutellum (Fig. 2, ps, s, sl,psl). 

 Each scutum is represented by two widely separated oval pieces. 

 The thoracic pleurites are so modified as to bear little resem- 

 blance to those of the imago. Each leg (Fig. 4, C) consists of 

 a coxa, trochanter, femur, tibia and tarsus. The coxa has not 

 a meron, this being represented by the elevated portion of the 

 thorax to which the coxa is attached. A comparison of the 

 larva and imago of Corydalis shows how the meron has been 

 separated from the thorax and united to the coxa. The abdo- 

 men consists of nine segments, the ninth representing the 

 fusion of the ninth, tenth and eleventh of the insect embryo. 

 The first pair of abdominal stigmata are above (Fig. 2, si^), 

 the remaining seven pairs are on the midlateral line. The 

 anus, which functions as an opening for the extrusion of the 

 spinneret when the cocoon is woven, is minute, and lies on the 

 upper side of the last segment near the posterior border. 



Myrmeleon texanus, Banks. 

 Larva — Length including mandibles, 12 mm. (my specimens are not 

 apparently full grown). Head somewhat rectangular, suddenly narrowed 

 behind, emarginated in front, thicker behind than in front. Ocular ped- 

 uncles (,Fig. 4, o) short, conoid, each with six eyes, three of which are in 

 a row on the end of the peduncle, two more in line behind the middle 

 one of the first three, and the sixth near the outer margin. The antenna 

 (Fig. 4. a) reaches the first mandibular tooth, and consists of a variable 

 number of segments, from twelve to fourteen, first segment large, three 

 and one half times as long as broad, second more slender but of about 

 the same length ; remainder of antenna tapering toward the tip and com- 

 posed of short segments ; terminal segment as long as preceding two, 

 ending in a small hair. Mandible (Fig. 3, m) stout, distal tooth longest, 

 proximal shortest. First joint of palpus (Fig. 4, A) a little longer than 

 broad and about twice as long as the three remaining joints together ; sec- 

 ond joint slender ; third about half as long as second ; fourth nearly as long 

 as second and third together, pointed at tip, swollen on anterior side. The 

 abdomen varies in size and shape according to condition of the larva. 

 Eighth abdominal .segment with a pair of short horn-shaped projections 

 on posterior border below (Fig. 6, .1). The whole body clothed with 

 stiff hairs. Hair on lateral and anterior margins of head very long ; sub-
