Very similar to H. luguhris in genei^al appearance but at once 

 distinguished from the corresponding sex of that species by the 

 basal joint of the front tarsi being (like the other joints) channelled 

 beneath, and being scarcely wider than the 2nd joint ; — also 

 distinguished by the impunctate ventral segments. From E. major 

 and Icata it differs inter alia by the feeble emargination of the 

 front of its prothorax and the absence (from all points of view; of 

 a distinct gutter on the prothorax immediately within the thickened 

 margin.

Styrus. 

 Of this genus I have before me two species. One of them is 

 pretty certainly S. elongatulus, Bates (which I have no doubt its 

 author is right in considering identical with Nyctozoihis elon- 

 gatulus, MacL). The only points on which I hesitate as to the 

 correctness of my identification are that in my example the head 

 and prothorax are more even than Mr. Bates describes them, and 

 the smooth space on the disc of the latter (mentioned by Mr. 

 Bates) is scarcely indicated, while at the same time I should 

 scarcely call the puncturation of the ventral segments " fine," 

 although it agrees with Mr. Bates' description in being much 

 finer than that of the underside of the head and of the flanks of 

 the prothorax. Discrepancies so small would perhai)S hardly be 

 worthy of remark in respect of most descriptions, but the descrip- 

 tions of Mr. Bates are so remarkably full and accurate that any 

 discrepancy suggests a doubt.
