Genera and Species of Coleoptera. 123 



second minute, the third longest, the rest more or less moniliform and 

 becoming gradually thicker upwards. Eyes lateral, small, round. 

 Maxillary palpi strongly securiform, the labial very short and thick. 

 Prothorax narrower than the head, much contracted behind. Scu- 

 tellum none. Elytra connate, very convex, broadly elliptical. Legs 

 moderate ; anterior coxae globose, not contiguous ; tibia? unarmed, 

 haiiy at the base internally ; tarsi short, thick, hairy beneath, the basal 

 joint longer than the second, the penultimate bilobed. Prosternum 

 produced, rounded posteriorly, and remote from the niesosternum. 



An examination of the mouth might throw some light on the 

 affinities of this very curious little insect ; but as the only specimen 

 I have seen belongs to the British Museum, and moreover is not in 

 very good condition, this cannot be done at present. In habit it 

 resembles the Anthicidae, but the globose anterior coxae separate it 

 from that family ; the bilobed tarsi, an unusual character amongst 

 the Tenebrionidae, suggest an analogy, or perhaps an affinity, with 

 Phymatodes and Phobelhis. It is one of the many important cap- 

 tures of Mr. Bates in the valley of the Amazons; and as that gen- 

 tleman is preparing a series of papers on some of the insects of his 

 extensive collections, it is to be hoped that this and many other 

 curious forms which he possesses will be at no distant date more 

 amply illustrated. 



Chcetylhis antJiicoides. (PI. VI. fig. 8.) 



C. niger, nitidus ; prothorace elytrisque tuberculatis, tuberculis setigeris ; 

 tarsis pallidioribus. 



Hah. Brazil (Ega). 



Black, shining; head coarsely punctured, with scattered, erect, 

 setulose hairs, a semicircular groove between the antennary orbits; 

 prothorax and elytra covered with large tubercular elevations, arranged 

 in rows on the latter, each of which bears a long, erect, setose hair ; 

 tarsi and base of the tibiae internally with pale silky hairs ; labial and 

 maxillary palpi at the base pale ferruginous ; antennae setigerous, as 

 long as the head and prothorax together. Length 2 lines. 



Dipsaconia [Tenebrionidae]. 



Head small, rather narrow and elongate below the eyes, deeply inserted 

 in the prothorax. Eyes transverse, undivided. Antennae rather short, 

 submoniliform, slightly hairy, the basal joint incrassated, the second 

 very short, the third longest, the remainder gradually decreasing in 

 length, but becoming broader and transverse, to the ninth and tenth, 

 the eleventh subovate. Labrum rounded anteriorly. Maxillary palpi 

 rather long, claviform, the last joint large, ovate, truncate ; the labial 

 very small ; external maxillary lobe broad, strongly ciliated. Mentum
