macula ferruginous: postpectus and abdomen at base blackish, punctures 

 dilated, distinct. 



Length over three twentieths of an inch. 



Four specimens. 



GENUS HYPHIDRUS. 



H. *punctatus. Distinctly and regularly punctured, dull testaceous ; 

 head with two dilated frontal impressions ; thorax blackish at tip and base ; 

 coleoptra fuscous on the disc, with about four obsolete paler macula; on each 

 elytron. 



Length over one tenth of an inch. 



Specimens twelve. This insect must closely resemble Laccopliilus punc- 

 tatus, Say, but cannot belong to that genus. 



GENUS HALIPLUS. 



H. *immaculicolUs. Pale ochreous yellow ; head and thorax immaculate ; 

 each elytron with a dilated basal spot, tip, and suture near it, three submar- 

 ginal, and two subsutural spots black: The anterior subsutural spot dilated 

 and confluent with the corresponding one on the other elytron: strise with 

 large black punctures. 



Length one tenth of an inch. 



Variety. Elytra pale yellow, basal spot wanting, central common spot 

 of the coleoptra dilated, triangular, the others less distinct. 



Specimens twenty ; and of the variety three. Cannot be mistaken for 

 the 12-punctatus and triopsis, Say, the former of which is common here.

CORRECTIONS AND ADDITIONS FOR THE "CONTRIBUTIONS TO 

 ENTOMOLOGY." 



When the first number of the contributions was published, it was stated 

 that should any of the supposed new insects prove to have been previously 

 described, it would give me pleasure to acknowledge it when duly Informed. 

 About the last of April I obtained two volumes of the " Species general des 

 Coleopteres" of Count Dejean. Although this work was commenced in 

 1825, only the first and second volumes have yet reached this country. 

 They contain ample descriptions of many North American insects; and in 

 them we are anticipated in several of our supposed nondescripts, besides 

 the two following which have been published in the Farmer.
