behind the dark marginal callosity, the sides obliquely converging 

 anteriorly. Elytra considerably wider than the prothorax, long, 

 subparallel. Inner claw of anterior tarsi lobed, and outer claw of 

 the other tarsi cleft at tip, in (^. 



cj. Ventral segment 6 very broadly, subtriangularly emarginate ; 7 

 drawn out laterally into a pair of long, stout, curved forceps, the 

 acuminate apices of which overlap; 8 short, polished, glabrous, 

 tridentate at the apex (the compressed cariniform median portion 

 forming a prominent tooth between the two apical notches) (fig. 6) ; 

 9 narrow, produced into a long, spoon-shaped lobe on each side, the 

 exposed median process (flagellum) finely serrate laterally and the 

 tip of a sharp spine visible on each side of it (figs. 6a, 66). 



Length (excl. head) 5J-6, breadth l|-2 mm. (<^ $.)

Redescribed from two males and two females. Pic's 

 type {(^), from the same source, was found by him in the 

 Gorham collection placed under Discodon cinereum. The 

 male of this insect is superficially very like a small Podabrus, 

 which has differently formed tarsal claws, etc. The extra- 

 ordinary ventral structure of the male was not noticed by 

 Pic. The forcipate ventral segment is assumed to be the 

 seventh (the first being hidden beneath the coxae) and 

 homologous with the normally cleft last exposed segment. 

 D. podabroides should perhaps be taken as the type of a 

 separate genus.

Narrow ((J), broader ($), elongate, moderately shining; clothed 

 with rather long brownish or cinereous pubescence; nigro-piceous 

 or black, the head on each side in front, the base of the mandibles, 

 and the prothorax (a median vitta, oblong patch, or small spot on 

 the disc excepted) straw-yellow, the humeri usually, and sometimes 

 the scutellum also, testaceous. Eyes large and prominent (c^), 

 smaller ($). Antennae slender, long, sparsely pilose in both sexes. 

 Prothorax ((J) transverse, rounded in front, deeply excavate on each 

 side of the disc, anteriorly, the sides abruptly, angularly notched 

 at the middle, the hind angles rectangular; in $ broader, with the 

 sides simply sinuate and the hind angles obtuse. Elytra long, a 

 little wider at the base than the prothorax in both sexes, not ex- 

 planate laterally, feebly costulate on the disc. Inner claw of anterior
