rax and elytra being of nearly equal breadth ; the apices of the elytra 

 are shghtly divaricating, each ending in an obtuse point : the legs are 

 remarkably short, and the femora slightly incrassated. The only de- 

 scribed Cerambycites which seem to approach the genera Tetraglenes 

 and Spalacopsis are Pachypeza [Serv.) pennicomis [Germar), Megace- 

 i-a macrocera [Serv.)^ and Hippopsis [Enc.) lemniscatus {Fah.)-, but 

 the eye in each of these three genera possesses the normal form. In the 

 cabinet of the Entomological Club are three species of Spalacopsis, to 

 the largest of these, which is from the interior of Brazil, I propose 

 giving the name of Spalacopsis Stellio. Its antennae are longer than 

 the body, brown and very pilose ; the first joint is quite as long as the 

 head and prothorax together, and its basal rather more slender than 

 its apical portion : the head and prothorax are punctured, mouse-co- 

 loured, with three indistinct longitudinal paler lines common to both ; 

 in the middle pale line of the head is a central furrow : the elytra are 

 mottled, the colours being the same as those of the head and protho- 

 rax ; each has four broad but indistinct and shallow fiirrows, these as 

 well as the interstices between them are impressed with crowded punc- 

 tures arranged in rows : the sides of the elytra are perfectly parallel, 

 and they are throughout rather wider than the head and prothorax. 

 The length is "4 inch, the breadth "05 inch. The second species — 

 Spalacopsis stolata — is a native of East Florida, and was taken at St. 

 John's Bluff in that State by Messrs. Doubleday and Foster. Its an- 

 tennae are shorter than the body, and fui-nished with a few scattered 

 hairs ; the basal joint is stout, cylindrical, of uniform substance and 

 rather longer than the head : the entire insect is of a dull grey or ash 

 colour, with a broad, brown, irregular, sutural vitta on the elytra; these 

 at the base are of uniform breadth with the prothorax, but are gradu- 

 ally dilated beyond the middle ; they are very ample, exceeding the 

 abdomen in length and breadth ; they are punctated, the pimctures 

 ranging in seven not very exact but crowded series. The length is 

 •35 inch, the breadth *049 inch. The third species — Spalacopsis suf- 

 fusa — has the antennae and body of nearly equal length ; the basal 

 joint stout, cylindrical, of nearly uniform size throughout, and mani- 

 festly longer than the head : the colour is a pale grey, with scarcely 

 any variety of shade : the elytra are strio-punctate, their base being 

 of uniform width with the prothorax. The length is '2 inch, the 

 breadth •025 inch. It inhabits Florida, and was taken in company 

 with the last, of which it may possibly be a variety, the principal 

 discrepancies being those of size and colour.
