with two transversely placed reddish spots on the disc ; the mandibles 

 rufescent. Head short; eyes rather small; antennae (cj) long, 

 slightly tapering outwards, densely set with short projecting hairs ; 

 ($) shorter and more sparsely pilose. Prothorax ((J) transverse, 

 densely punctulate, bicallose on the disc towards the base, the 

 margins broadly, deeply, angularly excised behind the middle, the 

 hind angles subrectangular ; ($) broader, with the margins simply 

 sinuate, uninterrupted, and somewhat thickened. Elytra wider 

 than the prothorax, subparallel in ^, broader and distinctly explanate 

 in 9; densely, rugulosely sculptured, costulate in (J. Inner claw 

 of anterior tarsi angularly dilated at base and cleft at tip, and outer 

 claw of the other tarsi cleft at tip, in ^.

(J. Last dorsal segment simple ; seventh ventral segment narrowly 

 cleft throughout ; eighth segment broad, transverse, notched in the 

 middle and sinuato-truncate at the apex (fig. 5) ; ninth segment 

 oblong, subtruncate at the tip, a stovit hook visible on each side of 

 it beneath and two minute hooks projecting from the internal sac.

Numerous examples of both sexes of the dark form, three 

 only of the variety. Very like D. (Silis) anale, Gorh., but 

 broader and less shining ; the antennae of the male more 

 densely pilose and the p3^gidium (or last dorsal segment) 

 simple in this sex; the hind angles of the prothorax of 

 the female not projecting laterally. The (^ characters of 

 the present insect are very similar to those of D. nigro- 

 pilosum. The sexes might be mistaken for different 

 species. Two males have been dissected. 



15. Discodon subtenue, n. sp. (Plate III, fig. 1, c^.) 



Narrow, slender, shining, cinereo -pubescent; black, the anterior 

 portion of the head, the base of the antennae, the prothorax (a broad 

 median vitta or spot excepted), the coxae and trochanters, the basal 

 half of the femora, the tibiae in part, and the margins or more of the 

 abdomen, flavous or testaceous ; the elytra (except in one $ example) 

 each with an oblique discoidal stripe of variable extent (sometimes 

 leaving only the suture and base black), and often the outer limb 

 also, dilute testaceous ; the antennae, tibiae, and tarsi (and in one 

 immature example the anterior and intermediate femora also) rarely 

 testaceous, the femora black in one specimen. Eyes small, prominent
