Batres.—On a New Genera and Species of Heteromera. 297 - 
prothorax finely and, except on the epistoma, not very closely punctured ; 
elytra punctate-striate, the strie distinctly deeper and the punctures a little 
larger than in A. hydrophiloides ; intervals finely and not closely punctulate ; 
under side and legs piceous; tarsi and basal joints of antenne paler ; lower 
margin of the four posterior femora emarginate ; anterior tarsi strongly 
expanded, the intermediate thickened ; antenna elongate. 
Length 34 lines. 
Hab. New Zealand. One example. 
: The peculiarities observable in the tibie and tarsi of the species are 
either sexual or subgeneric. 
Techmessa, g.n. ( Gidemeride ). 
Mentum transversely quadrangular. Last joint of maxillary palpi 
cultriform, acute at apex. Mandibles bifid at apex ; labrum short, slightly 
sinuously truncated in front. Head short; epistoma broadly and squarely 
truncated in front. Eyes large, slightly transverse, entire, more fcélor) 
or less (telephoroides) strongly prominent. Antenne inserted on slight 
prominences in front of, and quite distinct from, the eyes; joint first, 
swollen, pyriform; second, a little shorter than third, and both obconic ; 
third, not more than half as long as fourth ; fourth to tenth, sub-equal, 
cylindric (concolor) or elongate-obconic (telephoroides) ; eleventh, a little 
longer then the tenth, subfusiform. Prothorax scarcely wider than long 
and convex in concolor; distinctly wider than long, subdepressed, and 
somewhat unequal in telephoroides; truncated at base and apex; sides 
rounded, abruptly incurved anteriorly, gradually contracted posteriorly, 
tather strongly grooved or margined along the base. LElytra elongate, 
parallel, seareely convex, somewhat broadly rounded at apex. F'emora 
sublinear ; tibie armed with two distinct spurs at apex; the two penulti- 
Tate joints of the tarsi rather short, expanded, and spongy pubescent 
beneath. Abdomen of five free joints. Body more (telephoroides) or less 
(concolor) linear, shortly pilose. 
Of all the published genera of the (idemeride the present seems to me 
" approach nearest to Cycloderus. It is, however, at once to be dis- 
guished from that genus, and from all the others of the family known to 
me, by the short third joint of the antenne. 
Techmessa concolor, n. sp. 
: Black, a little shining ; everywhere rather densely clothed with a short- 
ish, semi-erect, brownish pile. Head and prothorax coarsely punctured 
va aie, the punctures more crowded on the front of the former and on 
., the latter; elytra rather strongly and closely punctured, and 
ae y confluently rugose ; under side and legs brownish black, pubes- 
rondy ctured; antenne (save the three basal joints) and mg -dusky-
