CLASSIFICATION OF TUE ASOALAPUIDiE. 249 



Like the last, tliis species approaches Oordulecerus in its wing- 

 formation. I have examined about half a dozen individuals, 

 which differ only in the presence or absence of tinting of the 

 wings.

 subtus vix flavescente. Caj)ut thoraxque dense aureo griseoque vil-

 cubito inferiore postcostaque flavidis. Long. corp. 12'"; exp. alar, 

 antic. 28"', postic. 2G'". 

 Hab. Santarera (Bates). In the British and Oxford Museums. 

 A pretty species, remarkable for its long and narrow wings, 

 and the delicate golden suffusion, which shows a tendency to in- 

 vade both pairs, but is most evident on the posterior. 



^ Geuus CoLOBOPTEBUS, jRambur. 

 (Suphalasca, part., Lefebv.) 



Wings long and narrow ; the extreme base of the inner margin 

 of the anterior pair with an excision, but not appeudiculate ; 

 posterior pair ordinarily with a deep excision before the base 

 of the inner margin, and then a dilatation, but varying much 

 in form : network moderately open ; no oblique branch of the 

 lowxr cubitus in the posterior wings, ^he postcosta being 

 long and sinuous ; pterostigma small. 



Antennae as long as, or longer than, the wings, more or less pro- 

 vided with verticillato hairs in the basal portion ; club long 

 and slender. 



^yc5 with the divisions equal. 



Thorax viliose, especially on the breast. 



Abdomen rather short, slender in the c? and without appendices ; 

 more robust in the $ . 



JOe^s long and slender ; spurs of the posterior tibiae as long as, 

 or longer than, the first four tarsal joints. 



Hab. South America.
