Curicta drakei sp. new. 



Size. Length from 16 mm., in case of smallest male, to 22 mm., in largest 

 female — not counting the respiratory filaments, which are from 7 to 8 mm. 

 long. The width of the head, including the eyes, from 2 mm. to 2.25 mm.; 

 the greatest width of anterior part of thorax, 2.5 mm. to 2.8 mm.; the 

 greatest width of posterior portion of thorax, 3 mm. to 4 mm.; the greatest 

 width of abdomen, 3.6 mm. to 4.75 mm.; the length of pronotum measvu-ed 

 along the dorsal median line, 3, mm. to 3.6 mm. 



Color. Obscured by incrustations, which color it from gray to black. 

 The cleaned insect is yellowish to dark testaceous, the dorsum of abdomen 

 red. 



Shape. Relatively slender; greatest width of thorax is to length of body 

 approximately as 1 is to 5.4. Sides of thorax and abdomen nearly parallel. 



Structural characteristics. The head wider across the eyes than distance 

 from caudal margin of head to tip of lora. The length before the eyes greater 

 than that behind them. Ej^es small, globular. Tylus longer than juga. The 

 head longitudinally carinate. 



Penultimate segment of antennae with long, slender lateral prolongation 

 (see fig. 7, pi. XLVII). The pronotum with anterior lateral lobes not greatly 

 swollen; the lateral margins, therefore, not greatl.y curved. Three longitudinal 

 grooves on disc of pronotum, the median one broad and straight, dividing 

 the median longitudinal elevation into two parallel carinse, laterad of which 

 are the deep lunate grooves terminating caiidolaterally in deep depressions. 

 The posterior enlarged portion of pronotum bears four more or less distinct 

 longitudinal carinae, which in some specimens appear to arise as bifurcations 

 of the two prominent carinse before them, and again as independent eleva- 

 tions. Scutellum tricarinate, the median carina more prominent on posterior 

 half, the lateral carinse slightly curved and terminating about the middle of 

 the lateral margins of the scutellum, these elevations and declivities often 

 accentuated or obscured by incrustations. Membrane of wings well de- 

 veloped, as long as the elytral suture, reticulate, the apex of the wing cover- 

 ing the basal two-fifths of the genital segment. Operculum of male genital 

 segment semicylindrical and slightly constricted before the apex, which is 

 bluntly pointed and faintly carinrtte. The metasternal plate short, caudal 

 margin nearly straight, the posterolateral prolongations attaining less than 

 half the length of the coxae and exposing a large elevated area (as long as 

 wide) of sternite behind it. Front coxa and femiu- stout, coxa one-half length 

 of femur, which bears its rather well-developed tooth nearer the base than the 

 apex. This tooth is located on the inner edge, two-fifths of the distance from 

 the trochanter to the apex of the femur. Tibia one-half as long as femur, 

 the apex of the short tarsal segment barely attaining the middle of the tooth 

 when tibia is flexed. Mesothoracic femur one-fourth longer than the tibia, 

 which is two and one-half times as long as the tarsus without the claws. 

 Metathoracic femiu' and tibia of equal length, the tibia about three' and one- 

 half times the length of tarsus without the claws, which are one-third the 

 length of the tarsus. 



Notes. The above species is described from a series of 20 speci- 

 mens, 16 of which were collected by Mrs. Grace Wiley in Colorado
