9 . Beak longer than the prothorax, more slender; sides of prothorax 

 more strongly converging from the base, rounded and not angulated in 

 front of the middle. 



Capron and Sand Point, Florida, Messrs. Hubbard and Schwarz. On 

 leaves of Chamcerops palmetto, abundant; varies in having a broad, dorsal, 

 prothoracic stripe brown; also in the elytra band becoming obsolete. 

 Thi? species is Derelomus signaticollis and flavicans of Dej can's Catalogue. 

 D. troglodytes is smaller and entirely testaceous, but is probably only an 

 individual variation. 



Tribe XIV. i, JEMOSACCIXI. 



This tribe is composed of a single genus Lcemosaccus, of which one 

 species occurs in our Southern States. It is easily known by the exposed 

 pygidium; the large, prominent and distant front coxae, and the breast not 

 channeled. The side pieces of the mesothorax are very transverse, and in- 

 tervene somewhat between the prothorax and elytra; the episterna of the 

 metathorax are wide, and the epimera are visible behind. The ventral su- 

 tures are straight; first and second segments equal, longer than the third 

 and fourth. The legs are stout and short, and the tibiae are strongly hooked 

 at tip; the tarsi are dilated, and the last joint is very slender, with two very 

 small, simple claws. 



The beak is short, stout and cylindrical ; the antennal grooves extend to 

 the lower margin of the eyes, which are oval and transverse. The antennas 

 are inserted about the middle, and are scarcely geniculated; the funicle 

 consists of seven joints and merges gradually into the oval, annulated, 

 pubescent club. There is nothing peculiar in the mouth; the gular pedun- 

 cle is long, the mentum small, and the palpi short and small; the mandi- 

 bles are curved, and of the usual form. 



The affinities of this tribe seem to be in the direction of Barini.

Middle, Western, and Southern States, as far as Texas; not rare on oak 

 leaves. Varies in the size of the red elytral spot, which sometimes occupies 

 the whole disc, leaving only a narrow margin black. The beak is opaque, 

 flattened above and rugosely punctured in $; cylindrical, shining, and 

 sparsely punctured in 9 



Tribe XV. CRYPromiYNCmNr. 



This tribe contains a large number of genera, which differ so much in 

 appearance and details of structure, that scarcely anything can be predi- 

 cated of all. It may, however, be stated in general terms, that while
