specimen only is known. D. alholateris is as large as the 

 same sex of I), lampyroides, from Guatemala, etc., but has 

 a broader prothorax, which is narrowed from near the 

 base, etc. It can be placed near the latter for the present.

Black or piceous, the head on each side in front, and sometimes 

 the epistoma also, the base of the mandibles, and the prothorax 

 (a broad median vitta, or a triangular or cruciform patch on the 

 disc, and sometimes a small spot on each side in c?, excepted) 

 flavous or rufo-testaceous. Antennae (J') moderately long, rather 

 stout, subserrate, tapering towards the tip, closely pilose; ($) 

 shorter, sparsely pilose. Eyes rather small in both sexes. Pro- 

 thorax transverse, with a narrow, deep, straight incision on each 

 side at about one-third from the base in (^ ; wider in $, with the 

 margins broadly explanate and feebly sinuate. Elytra at the base 

 about as wide as the prothorax, in $ usually more or less explanate 

 at the sides. Anterior tarsi dilated in (^. Inner claw of anterior 

 tarsi and outer claw of intermediate tarsi broadly lobed, and outer 

 claw of posterior tarsi deeply cleft (the outer portion of the claw 

 submembranous, and shorter and broader than the other), in (J. 

 Sixth ventral segment of c? very deeply, triangularly emarginate, 

 the seventh long, and with the two lobes compressed and sub- 

 angularly raised posteriorly, the median fissure becoming rather 

 broadly open anteriorly, leaving a portion of the smooth, shining 

 eighth segment exposed. (Fig. 23, profile view.) 



Var. o. The sutural and outer margins of the elytra, and some- 

 times the apical third indeterminately, the margins and apex of the 

 abdomen, and the femora and tibiae in some specimens, testaceous 

 or flavous. <$ $.
