PSETJDACAMPTUS.— CHCEKOKEHYNCHTJS. 3 



PSEUD ACAMPTUS, gen. nov. 



Head deeply inserted into the prothorax, large ; the eyes inferiorly placed, hidden in repose ; rostrum 

 deflexed, the tip resting on the anterior coxae, very stout, short, parallel-sided, nearly straight, with 

 deep, oblique scrobes, the antennae inserted at about the middle, the funiculus 6-jointed, the club abrupt, 

 small, ovate, with a shining, subglabrous basal joint and the other joints very short and densely 

 pubescent ; profchorax subtubulate and cucullate in front, feebly sinuate at the base, and deeply 

 emarginate at the apex beneath ; scutellum small, oblong-subquadrate, flat; elytra much wider than the 

 prothorax, subtriangular, sinuate at the base, their apices strongly declivous and abruptly produced ; 

 ventral segments 3 and 4 short, together about as long as 5 : prosternum broadly and deeply excavate 

 from the apex to the narrowly separated anterior coxae ; legs stout ; tibiae sinuous within, strongly 

 unguiculate at the outer apical angle and mucronate at the inner angle ; tarsi sparsely pilose beneath, 

 the third joint simple, the claws divergent and widely separated; body oblong, densely lutose and also 

 thickly set with stout clubbed setae. 



Type, P. plurisetosus. 



The Mexican insect from which the above characters are taken is nearly related to 

 the N. -American genus Acamptus, Lee, but the funiculus is 6-jointed *, the elytra are 

 more sinuate along the basal margin and have more prominent humeri, and the 

 clubbed setae extend along each interstice. The sculpture is almost entirely hidden

1. Pseudacamptus plurisetosus, sp. n. (Tab. I. figg. 2, 2 a- 



Oblong, somewhat flattened above, opaque, alutaceous, nigro-piceous, the antennae ferruginous ; densely 

 incrustate with brown scales and also thickly set with short, stout, erect, clubbed setae (which extend to 

 the legs, rostrum, and antennal scape), those on the elytra uniseriately arranged down each interstice, 

 the last joint of the funiculus also with several long projecting setae. Head and rostrum densely, finely 

 punctate. Prothorax about as long as broad, slightly rounded at the sides from the well-marked 

 subapical constriction to the base, the tubulate portion nearly half the length of the posterior portion ; 

 closely punctate. Elytra moderately long, seriate-punctate, the interstices feebly convex, 3 and 5, and 1 

 (sutural) towards the apex, distinctly raised. Beneath sparsely punctate. 



Length 3f , breadth 1| millim.

Hob. Mexico, " Sierra de Durarago " {ex coll. Flohr). 



One specimen, probably from the State of Vera Cruz. The seta? in this species are 

 much stouter than in Acamptus rigidus (for an example of which we are indebted to 



Mr. Wickham), and those on the elytra are not confined to the alternate interstices, as 



in A. rigidus and A. echinus.

CHCERORRHYNCHUS, gen. nov. 







Head deeply inserted into the prothorax, large ; eyes inferiorly placed, almost hidden in repose ; rostrum 

 deflexed, the tip resting on the anterior coxae, very short, stout, and parallel-sided, feebly curved, 

 somewhat depressed at the base, the scrobes deep and obliquely descending, the antennae inserted slightly 

 beyond the middle, the funiculus 7-jointed, joints 3-7 strongly transverse, widening outwards, the club 

 rather large, ovate, and closely pubescent, its basal joint shorter than the others united ; prothorax 

 subtubulate and cucullate in front, feebly sinuate at the base, and deeply emarginate at the apex beneath ; 



* Acamptus rigidus, Lee, has the funiculus 7- (not 6-, as stated by its describer) jointed, a fact already 



pointed out by Casey (Ann. N. York Acad. Sci. vi. p. 446).
