Arizona (Tucson). Mr. H. F. Wickham. 



This exceedingly interesting and aberrant species is easily recog- 

 nizable by its rather long antennas, conspicuous pronotal fringe and 

 coarse black vestiture ; it will probably have to be ultimately sepa- 

 rated from elongata as a distinct genus. 



PALEMBUS n. gen. 



I have applied this name to a small species, having very nearly 

 the antennal structure of Oplocephala Lap. (= Evoplus Lee), and 

 apparently allied to that genus, but differing in its narrower, more 

 depressed form, non-tuberculate head, large coarsely faceted eyes, 

 longer hind tarsi and entire epipleura? ; its general characters are as 

 follows : — 



Body parallel, rather strongly convex. Head rather short and broad, the 

 eyes large, more prominent than the sides before them ; antenna? short, the 

 last seven joints short and transverse, forming a long loose parallel club ; 

 maxillary palpi rather slender, the last joint elongate-oval, about as long as 

 the preceding two together, the apex obliquely and narrowly truncate ; 

 mentum obtrapezoidal ; ligula large, corneous, the connate paraglossae large, 

 broadly rounded. Prothorax transverse, the prosternum moderately wide 

 between the coxae. Elytra striate ; epipleurse narrow, entire, fiat. Legs 

 rather slender, the anterior tibiae not dilated ; posterior tarsi long, but 

 slightly shorter than the tibiae, the basal joint equal to the last and as long 

 as the second and third together, the third one-half longer than wide. 



In the type specimen the structure of the middle coxal cavities 

 cannot be clearly discerned. 



P. ocularis n. sp. — Oblong-elongate, convex, pale rufo-testaceous 

 throughout, shining, glabrous. Head evenly, feebly convex, finely, moder- 

 ately densely punctate behind, the epistoma rather large, abruptly deplanate, 

 feebly convex and very minutely punctate, the sides strongly convergent, the 

 apex broadly truncate, the surface feebly impressed just before each eye ; eyes 

 large, separated above by scarcely their own width ; antennae one-third longer 

 than the head, stout, compressed, the third joint a little longer than the 

 fourth and one-half longer than the second. Prothorax four-fifths wider than 

 long, the apex and base equal, the former broadly, feebly, evenly arcuate, 

 almost truncate, the latter arcuate in the middle, oblique thence to the basal 

 angles which are obtuse and blunt, apical rounded ; sides feebly arcuate 

 behind, nearly straight anteriorly ; disk slightly widest near basal third, 

 evenly, transversely convex, distantly and feebly biimpressed at base, very 

 finely, not densely punctate. Scutellum slightly wider than long, ogival. 

 Elytra between three and four times as long as the prothorax, equal in width 

 to the latter, fully twice as long as wide, parallel, obtusely rounded behind,
