New Species of Heteromera. 313 



shoulders somewhat prominent but rounded, gradually- 

 widening* to three-fourths their length, thence sinuously 

 contracted to the apex, which is somewhat acute ; lateral 

 edges sharp, strongly sinuous, tuberculate on their basal 

 fourth ; on each elytron a row of variously sized tubercles 

 down by the suture, extending to the extreme apex, the 

 tubercles becoming linear-elongate as they approach the 

 hind extremity ; besides this, there are nine more or less 

 strongly interrupted, elevated, polished lines or ridges"; 

 2, 4, 6 and 8 being the most continuous ; 2 and 6 are 

 united near the hind extremity, and enclose 3, 4 and 5 ; 

 1, 3, 5 and 7 are much broken up, consisting of but 

 distant elongate tubercles, and row 9, which is submar- 

 ginal, is much abbreviated at each end, and consists of 

 small sub-elongate tubercles ; the intervals are pitted with 

 large shallow punctures, much more strongly and closely 

 so on the epipleurje or inflexed sides of the elytra, and 

 have a few short scattered squamose hairs, more plenti- 

 fully distributed at the hind extremity ; the epipleural 

 fold is strongly sinuous, sub-horizontal in the apical half, 

 suddenly expanded near the hind extremity, and very 

 deeply and closely punctured, especially at the base ; 

 parapleurfe, sides of sterna, and sides of abdomen, spar- 

 ingly impressed with large coarse punctures ; cheeks and 

 head beneath, coarsely rugose-punctate ; thighs and tibiee 

 compressed, impunctate, the former attenuated at the 

 base, and all simple ; the fore tibiae are very slightly 

 curved, somewhat thickened within, close to the apex, in 

 the form of a broad blunt tooth, and fringed with short 

 hairs ; the intermediate and hind tibiae are very slightly- 

 sinuous, with the apex of the latter acutely produced 

 within ; save the anterior (on which two very short spurs 

 may be detected) the tibite are without spurs ; the pro- 

 sternal process terminates behind in a small compressed 

 point.

It is with considerable hesitation (hence the lengthy- 

 description) that I include the above species in the 

 genus Goniadera, there being a decided tendency in the 

 penultimate joint of the tarsi to assume the sub-bilobed 

 form characteristic of the next sub-family — the Hetero- 

 tarsince : in this respect, as well as in the sub-tuberculate 

 surface of its prothorax and elytra, the spurless tibiee,* 



* In the genus Anoidus, the tibiae, contrary to the statement of 

 Lacordaire, are all visibly spurred.
