abdomen pale, brown towards tip. Wings hyaline, pterostigma in both pairs very 

 distinctly brown ; venation mostly pale, many of the cross-veins dark at ends, both 

 gradate series brown. Divisory veinlet of the third cubital cell starts near the lower 

 end of the cross-vein ; wings rather broad and rounded at tips. Length to tip of 

 wings 15 mm. 



Two specimens from Guatemala. A very distinct species because 

 of the prominence of the pterostigma in all wings and the two brown 

 dots on pronotum. 



Chrysopa aztecana, sp. nov. 



Face yellowish, a black semicircle along base of clypeus ; basal joints of antennce 

 pale, beyond deep black ; palpi black, narrowly banded with pale, vertex pale, with 

 a median line and a reddish spot each side ; pronotum pale, brown on sides ; rest of 

 thorax pale ; abdomen brown. Wings hyaline, pterostigma not marked ; venation 

 brown, except the subcosta, radius, and median veins, which are pale. Two series 

 of gradate veins in both wings ; divisory veinlet ending beyond the cross-vein. Wings 

 rather narrow, and acute at tips in both pairs. Length to tip of wings 15 mm. 



One specimen from Truxpan, Mexico, September 5 CMcClendon).

Corydalis texana, sp. nov. 



General color luteous, blackish around ocelli, two punctate streaks behind scarcely 

 paler, pronotum with the hastate and lateral scars hardly paler than general surface ; 

 antennae blackish, basal joints yellowish ; legs yellowish, darker on base of tibia and 

 on tarsus. Wings with one white spot in each costal cell, the latter very regular in 

 size, many white dots scattered through the other cells ; forkings and cross-veins 

 mostly black ; costal cross-veins black at ends, longitudinal veins yellow, a few small 

 indistinct clouds in some cells, the pterostigma scarcely infuscated. Head not very 

 broad, in both sexes with a tooth behind eye ; male mandibles but little longer than 

 those of female, their greatest length hardly equal to length of head, without a free 

 tooth at base of the apical part or fang. Superior male appendages not very long, 

 incurved, and twisted toward tip ; inferior appendages upturned and clavate. Length 

 from tip of mandibles to tip of wing but 48 mm.; expanse of wings 76 mm. 



One pair from Laredo, Te.xas, August 13 (McClendon). Sepa- 

 rated from all others by small size, small mandibles, and especially 

 from C. cognatd by absence of a subapical tooth to male mandibles, 

 and by the pale color of the scars on pronotum. Mr. Davis in his 

 recent monograph of the Sialidae has described a species from Ithaca, 

 N. Y, as Chauliodes concolor ; it differs, according to table, from C. 

 angusticollis in having black instead of brown antennae. No other 

 differences are given in the description. I have sjiecimens from Ithaca 

 which have brown antenn^^. This difference, I think in this family, 

 is not worthy of the barest notice; certainly it is not of specific value, 

 and C. concolor is ecjual to C. augusticollis. I also think that Mr.
