Coloration. — General coloration blackish, tinged with claret 

 brown (intensive), varying to blackish claret brown, this paler on 

 pronotum, mesonotum and metanotum (recessive). The prono- 

 tum is usually immaculate, but sometimes shows traces of lateral 

 paler bands; occasional specimens have a small area there of buffy, 

 tinged with claret brown, while rare specimens have broad lateral 

 bands of ochraceous-orange, tinged laterad with morocco red, this 

 banding again indicated, but not as heavily, in the marginal field 

 of the tegmina and laterad on the metanotum. In specimens of 

 recessive coloration, the head is morocco red, the ocellar areas, face 

 below the antennal sockets and clypeus, ochraceous-buff. The 

 exposed ventral portions of pronotum, mesonotum and metano- 

 tum, ventral surface of thoracic segments and coxae, ochraceous- 

 buff, the coxae lined proximad with deep claret brown. The 

 femora morocco red, the tibiae and tarsi deep claret brown, the 

 pulvilli buffy. The ventral surface of abdomen, of general colora- 

 tion. In the n-iaximum intensive condition, the clypeus and small 

 areas on the ventral surface of the pronotum, mesonotum and 

 metanotum and on the coxae, alone arc buffy. 



"3 These valves are not completely separated. An expansive integument joins their 

 inner margins; upon this the ootheca rests when partly extruded, the valves gripping 

 its sides.
