cereal bases where feeble concavity is indicated, very broad, with free margin 

 evenly and broadly convex. 



Head blackish chestnut brown, ocelli, mouthparts and maxillary palpi buffy. 

 Antennae mummy brown. Pronotum shining, chestnut brown, narrowly margined 

 laterad, except more broadly in area just caudad of discal sulci, and very narrowly 

 margined cephalad with warm bufif, the disk with a medio-longitudinal streak of 

 tawny, which is broadest before the caudal margin. Tegmina translucent, light 

 chestnut brown, with costal field dark in internal half, chestnut brown and in 

 half toward costal margin warm buff. Wings ver\- wcakh- suffused with brown, 

 area of costal veins darker. Dorsal surface of abdomen bufi'y suffused with prout's 

 brown, darkened distad. Cerci chestnut brown. Proximal portion of coxae black- 

 ish chestnut brown, the remaining portions of the limbs buff\- with spines tawny. 

 Ventral surface of abdomen blackish brown, except mesad and narrowh- along the 

 caudal margins of the segments, where it is buffy. 



The series of males approximate this, the type, in coloration. In the maximum 

 recessive condition the dark portions of the pronotal disk are much reduced, russet, 

 the pale median line more extensive and continued out each of the latero-caudal 

 sulci to the pale lateral margin, thus dividing the dark suffusion of the pronotal 

 disk into four parts. 



The females are all more intensive in coloration than the males. The allotype 

 has the entire pronotum blackish chestnut brown, except the narrow pale margin 

 and a narrow suffused medio-longitudinal line of hazel. Those from Old Panama 

 and Panama City show only a feeble trace of the medio-longitudinal line of paler 

 coloration, while the specimen from Chorrera has the pronotal disk solidly blackish 

 chestnut brown. In the two darkest examples the distal portion of the fourth 

 and all of the fifth joints of the maxillary palpi are heavily suffused with blackish 

 chestnut brown. 



A large immature female is entirely blackish brown, except for a paler longitutinal 

 suffusion mesad on the mesonotum and metanotum of russet, and the cephalo- 

 lateral margins of the pronotum and lateral margins of the mesonotum and metano- 

 tum which are ochraceous-buff.
