Teochalus vagus, n. spec, 



Plate XLVL, fig. 31. 



Keddish, metallic, shining, or clothed with a sub-opaque 

 moderately iridescent indumentum ; antennae flavous ; body 

 ampliato-ovate, convex ; clypeus narrowed in the anterior part 

 where it is straight laterally, thence broadly ampliated, with the 

 upper margin strongly sinuate next to the terminal part of 

 the frontal keel, and barely reaching the depression of the anterior 

 part which is strongly reflexed, with the outer angles moderately 

 sharp and the median part plainly dentate, the clypeal median 

 longitudinal keel is long, the frontal keel high, and at a short 

 distance from the base there is a transverse groove reaching the 

 hind part of the eyes, and deeper in the male than in the female ; 

 the clypeus is sparsely punctate, the punctures on the frontal part 

 more numerous and therefore much more closely set; prothorax 

 gradually ampliated from the anterior to the posterior angles the 

 latter of which is sharp, it is twice as broad as long, deeply punctate 

 with the punctures separated by an interval nearly equal to that of 

 their own diameter ; scutellum very long, sharply triangular, closely 

 punctate ; elytra somewhat ampliated laterally in the middle, convex 

 in the anterior part, weakly striate in the dorsal, the striae numbering 

 five or six on each side, the intervals have the same punctuation as 

 the prothorax, and very few and very short setae near the humeral 

 part only of the outer margin ; the convex pygidium is very deeply 

 punctate, and briefly setulose along the margin ; the under side is 

 almost glabrous, except for the villose femora, the abdominal 

 segments are very deeply and numerously punctate, and the 

 trochanters of the anterior tibiae are very broadly dilated, and 

 the anterior tibiae bi-dentate. The shape of the genital armature 

 of the male is almost identical with that of T. byrrhinus (pi. xlvi., 

 fig. 31) when seen sideways, but the forceps-like clasps enclose a 

 wider space if seen from above. 



Length 7-8 mm. ; width 5-6 mm.

Teochalus damarus, n. spec. 



Elongato-ovate, convex, chestnut-brown, shiny, faintly iridescent,, 

 antennae flavous ; very closely allied in general appearance to 

 T. badius, but easily distinguished by the transverse impression 

 along the base of the head; it is plainly allied to T. vagus, but 

 whereas in that species the lateral margins of the clypeus reach
