380 INIr. D. Sharp's Contributions to the 



togetlier, obtusely pointed. Palpi yellow. Head broad; 

 the eyes very large, even broader than the elytra; the 

 clyiieiis armed in front with two very elongate, pitchy- 

 yellow spines, which are ciliated internally, the horny 

 clypeus deeply impressed and separated by a straight 

 depressed line from the front; the front with elevations 

 and depressions so placed as to form a central elevated 

 space, surrounded, except at the summit in the middle, by 

 a broad, irregidar depression; also with a fine depression 

 along the inner margin of the eyes, in which are a few 

 punctures. Thorax broad, with four transverse furrows 

 in which are large punctures; the first of these grooves is 

 placed near the front margin, whose course it follows; the 

 second extends in a nearlv straio-ht line across the thorax, 

 so that it is nearer to the front one at the sides than in the 

 middle, — it can scarcely be said to be interrupted in the 

 middle ; the third furrow is the broadest and is distinctly 

 interrupted in the middle, the hinder one is placed close 

 to the base ; the sides appear a little waved and have two 

 angular projections near the front. Scutellum emarginate- 

 truncate at the apex, bearing two fovew. Elytra broad, 

 broader than long, about as long as the thorax, deeply 

 impressed at the base for the thorax ; each near the 

 shoulder with an oblique stria, sharply limited on the 

 inner but not on the outer side. Legs yellow; coxi'c 

 castaneous. 



Ega; two specimens, both of which appear to be 

 females. 



Obs. — Besides the two females above descriljed, I have 

 also two males of this species, which I obtained from the 

 collection of iNIr. E. W. Janson, where they were labelled, 

 " Parti, Brazil." These two males have the ventral ])late 

 of the 7th segment of the hind body slightly emarginate 

 on each side the middle at the extremity; and the prc- 

 cediii"- segments are sli<rlitlv flattened along the middle, 

 and furnished there with a very fine and scanty short 

 ])ubescence. The structure of the antenniu is quite the 

 same as in the females.
