78 TRAVELS AMONGST THE GREAT ANDES. 



closely punctured. Antennte pitcliy red, club sliglitly darker and clothed 

 witli yellowish grey pubescence. Prothorax only slightly longer than broad, 

 somewhat narrowed both in front and behind, a little flattened on the disc, 

 rather finely and sparingly punctured ; sides arcviate, slightly sinuate in 

 front ; with a short, sliarp and moderately strong spine on each side neai' 

 the base. Scutellum very small, rounded behind, impunctate. Elytra about 

 as long as the rostrum, head and prothorax together, at the base considerably 

 liroader than the protliorax, gradually widening to just behind the middle, 

 strongly striate-punctate, the interstices not very Ijroad and smooth, with a 

 feeble impression on each side near the shoulder ; sides arcuately rounded 

 to the apex. Underside black, shining ; the sterna and first abdominal 

 segment very strongly and sj^aringly punctured in irregular transverse rows, 

 the other abdominal segments with only a few extremely fine punctures near 

 the sides. Legs black, tibise and tarsi pitchy. Length, 3f mm. 



As this insect is only rej^resented by a single example I think for the 

 present it will be better to regard it as an aberi^ant Otidocephalus ; perhaps, 

 when more specimens are available for examination, it will be found neces- 

 sary to establish a new genus for its reception. This insect may be readily 

 distinguished from all the described species by its comparatively In-oad spined 

 prothorax and strongly punctured surface.
