270 Mr. F. Bates' Descriptions of 



base, and a trace of a dorsal median line ; apex strongly 

 emarginate, the angles prominent, subacute and slightly 

 oiitwardly directed {$) \ base closely applied to the elytra, 

 more (?) or less parabolically emarginate at each side 

 {Duhoulayi), or simply bisinuate {Hoioitti), hind angles 

 prominent, directed behind and overlapping the humeral 

 angles of the elytra : scutellum small, situate on a lower 

 plane than the elytra, transverse, broadly triangular behind, 

 almost concealed when the base of the prothorax is closely 

 applied to the base of the elytra : elytra elongate-oval 

 {Diiboulayi) or briefly oval {Howitti), but little wider 

 ( $ Duboulayi) than the prothorax at its widest part, 

 middle of base truncated, shoulders broadly and slightly 

 angularly rounded and reflexed at the margins ; posteriorly 

 rather abruptly declivous, the apex a little produced: 

 epipleural fold concave from before the middle to apex 

 {$), only at the apex ( 2 ) : prosternum very full and con- 

 vex, the anterior coxte fitting rather loosely in their cavi- 

 ties : prosternal process horizontal, prominent behind, 

 terminating in a blunt point in Duboulayi ; curved round 

 the coxa3 in Hoioitti: mesosternum prominent, or convex 

 above, subvertical in front and narrowly concave, loosely 

 receiving the prosternal projection in repose in Duboulayi ; 

 flat above, declivous and broadly concave in front in 

 Howitti : episterna of mesothorax sub-triangular, partly 

 enclosed laterally by the epimera: mctasternum very short: 

 intercoxal process broad, sides parallel, apex very broadly 

 rounded or subtruncated : legs elongate, moderately stout ; 

 femora sublinear, rather strongly compressed ; anterior 

 tibic\3 sublinear, strongly compressed, slightly expanded 

 and keeled externally, having a broad sharp tooth near 

 the apex outwardly, and immediately in front of this a 

 semicircular excision, the apex broadly rounded ; the 

 outer spur large, robust, externally apical ; the inner 

 small, acute, internally apical : the four posterior tibire 

 slightly gradually thicker apically, slightly compressed 

 {Duboulayi), the posterior longer than the intermediate, 

 the outer apical angle acute (not dentiform), the outer 

 spur much shorter than the inner : tarsi elongate, sparsely 

 pubescent above, broadly concave ( $ Duboulayi) or 

 simply flattened (//(9?o/^i'/ and $ Duboulayi) and glabrous 

 beneath, the sides and apices densely fringed with fine 

 golden-yellow hairs, more (Hotvitti) or less (Duboulayi) 

 long ; 1st joint of the posterior longer than the two follow- 

 ine: united, the last elong-ate in all : 3rd and 4th ventral
