ECTINOGRAMMA COLLARE. (PI. XXVIII. fig. 10.) 



E. nigrum, subnitidum ; prothorace pedibusque anticis, tarsis 

 exceptis, rufo-castaneis. 



Very long, narrow, and nearly linear, black, subnitid, tbe pro- 

 tliorax and fore legs, except the tarsi, reddish chestnut ; head deeply 

 cleft between the antenna?, clothed with long pale-greyish hairs in 

 front ; prothorax finely punctured, scarcely wider than the head, the 

 sides nearly parallel ; scutellum narrow, rounded behind ; elytra 

 about five times as long as the prothorax, and but slightly broader, 

 the shoulders rounded, rather irregularly punctured, the apex of 

 each obliquely truncate ; body beneath and legs, except the anterior 

 pair, glossy black 5 antenna? setaceous, 1 2-jointed, rather longer than 

 the body, the basal joint elongate, cylindrical, its apex entire, the 

 third joint considerably shorter, but longer than the fourth, the rest 

 very gradually shortened, the twelfth the shortest. 



A most interesting genus, which M. J. Thomson has referred to 

 the Hippopsince on account of its contiguous antennary tubers— a 

 character, it is true, quite at variance with the Obereince, but which, 

 it appears to me, should yield to the insect's more obvious affinities 

 with that subfamily. His specimen was imperfect as to the an- 

 tenna? ; I have therefore subjoined a description of them. It will be 

 seen that they have the remarkable character of being 1 2-jointed; 

 but whether this is a sexual peculiarity or not cannot now be decided. 

 Ectinogramma isosceloides, the type, differs from the above in hav- 

 ing the head red : nothing is said about the legs ; it may be there- 

 fore inferred that they are unicolorous. 



Nedytisis. 



Elytra lateraliter haud deflexa. 



Prothorax capite latior, antice et postice constrictus et sulcatus. 



Femora postica elongata, cceteris brevibus. 



Coxae anticce contiguce. 



Head broad in front ; antennary tubers small and widely apart. 

 Eyes rather prominent, narrowly emarginate. Antenna? as long as 

 the body, setaceous, fimbriated beneath, the scape slender towards 

 the base ; third joint longer than the scape, the remainder gradually 

 shorter. Prothorax narrower than the head, cylindrical, constricted 

 and grooved anteriorly and posteriorly. Elytra short, nearly parallel, 

 not bent down at the sides, except a little at the shoulders, their 

 apices slightly dehiscent and pointed. Legs very unequal, the an- 

 terior and intermediate pairs (especially their femora) short, the 

 posterior femur two or three times as long as the anterior ; basal 

 joint of the posterior tarsi as long as the next two together. Claws 

 broadly appendiculate. Anterior coxa? prominent, contiguous, their 

 acetabula slightly angulated.
