MORGAN HEBARD I 95 



Coloration. — (Intensive.) Shining blackish brown. Head, from 

 vertex to clypeus, this color; ocellar spots, genae and clypeus, 

 buffy. Limbs, proximad, suffused ochraceous-buff ; tibiae and 

 tarsi russet, the latter paler. Tegmina translucent, blackish 

 chestnut brown; marginal field ochraceous-buff, wholly, or in part, 

 heavily suffused with blackish chestnut brown, cingulate costal 

 margin blackish chestnut brown. Abdomen with dorsal surface 

 dark brown, deepening caudad; ventral surface polished, broadly 

 margined with blackish brown, shading rapidly into brilliant, 

 suffused cinnamon rufous in large mesal portion. Pronotum shin- 

 ing blackish brown, with marginal traces of buffy latero-cephalad. 

 In specimens of the maximum recessive coloration this pale area 

 forms a marginal band, moderately broad cephalad and continued 

 along the lateral margins of the pronotum to near the latero- 

 caudal angles, while the tegmina are transparent, light ochraceous- 

 buff, with numerous microscopic dots of brown^^^ and humeral 

 trunk blackish brown proximad. In such specimens the dark 

 portion of the head sometimes shows a slightly paler transverse 

 marking, between the points of juncture of the eyes and ocellar 

 areas. Every degree of variation, from the maximum intensive to 

 the maximum recessive type of coloration, occurs. ^^'^ 



General coloration of immature examples, deep chestnut brown 

 to blackish chestnut brown. ^'^ Head, pronotum, mesonotum, 

 metanotum, median segment, first two dorsal abdominal segments 

 and \entral surface polished, with very minute, scattered, mi- 

 croscopic punctae on head and dorsal polished portions. Remain- 

 ing dorsal portion of abdomen microscopically finely shagreenous, 

 showing raised and polished points on third segment and fewer 

 raised points on the remaining segments. Head of general colora- 

 tion, shading to slightly paler on the occiput, cingulate margins 



'■' I'nder the microscope these dots are seen to be arranged in hnes between the teg- 

 minal veins, each dot representing pigmentation of a minute pit. These lines of dots, 

 become more and more broken distad and disappear before the distal portion of the teg- 

 men is reached. To the naked eye, the effect is of a moderate proximal suffusion of the 

 transparent tegmina. 



•■"** The single Malaysian male before us is of the maxinmm recessive type of coloration. 



319 Occasional specimens are found of paler general coloration. These represent indi- 

 viduals which, when killed, had but recently reached maturity and had not >et attained 

 their full coloration.
