to the Genus Haliplus of Latreile it is so strongly characterized 

 as not to be mistaken — These two Genera Hyphydrus & Hali- 

 plus perhaps are the same but of different Authors ? 



I have not been so fortunate as to obtain another specimen 

 of the Diopsis though I have hunted faithfully, it appears to 

 be a rare insect, and I have no doubt different from Illiger's 

 insect the description of which you were so good as to extract 

 for me ; yet like that it may be characterised "Nigra, alis fas- 

 cia (5lc ' ' but in the details it appears to differ — I have thought 

 to name it brevicornis as the peduncles of the eyes are not longer 

 than the distance between their bases, they are brown — head, 

 posterior spines, & feet pale yellow — poisers white. Thorax 

 brownish black, lateral spines & abdomen black — Fore thighs 

 very much thickened & with the shanks brown but the joints 

 are pale yellow — its length is 2 lines — I found it on the Swamp 

 Cabbage (Pothos foetida) — May 



When I had the pleasure to be at your house, amongst the 

 very interesting insects you shewed me one (of which you had 

 several specimens) that you thought was a new genus — it is an 

 elongated cylindrical insect — that which I take to be the male 

 is black, with a reddish thorax and black dorsal stripe — (Liune 

 would have placed it with Tenebrio) In looking over a ne- 

 glected draw[er] in my cabinet today I found a couple of 

 specimens of it & upon examining them but without discection, 

 I concluded that it approached nearest to the Genus Langicria 

 of Latreille & might be placed there but for its palpi which are 

 not filiform, — Elytra ver}^ dark green approaching black — 

 general colour of the female rather lighter. 



On the lid of the box within you will find two plates of In- 

 sects intended for my American Entomology they are all to be 

 coloured — I send you the plate of G. Tityus as the first one 

 that I have had coloured you will therefore not criticise it with 

 too much severity as the artist is young & will improve I have 

 the satisfaction to see in this first attempt that the thing is 

 practicable in this country, which has been heretofore much 

 doubted — The plate of Papilio Philenor will exhibit the style 

 of engraving which however is entirely obscured by the colour 

 when it is laid on & therefor need not be very fine its principle
