xliv PROCEEDINGS OF THE 



species of the genus Cremastocheilus, of which four were new. 

 Two of these were discovered in South Carolina, by Dr. Zimmer- 

 tnann, and two in the Missouri territory, by Dr. J. Leconte. 

 The three known species were Cr. canaliculalus, Kirby, Cr. cas- 

 tanece, Knoch, and Cr. Sayii, Harris. He stated that the Cr. 

 canaticulatus of Kirby, which is the Cr. Hentzii of Dr. Harris, 

 had hitherto been erroneously considered, both by himself and 

 Dr. Burrneister, to be the Cr. castanetje of Knoch. The true 

 Cr. casfanece had remained hitherto unknown to more modern 

 authors. It is distinguishable from the former species by its 

 much smaller size, and by its more coarsely and sparingly punc- 

 tured head and thorax. He pointed out that the third species 

 was very near to the C. variolosus of Kirby, but differed in the 

 form of the posterior angles of the thorax. He mentioned that 

 besides these, he was acquainted with five other species from 

 North America, thus bringing the actual number of known species 

 from that continent to amount to twelve. These five are, 1st, 

 Psilocnemis leucosticta, Burm ; 2, Cremastocheilus Harrisii, Kirby ; 

 fj, a large new species from Indiana, of which fragments exist in 

 Dr. Harris's collection ; 4, a species allied to Cr. variolosus, which 

 M. Gory had in his collection as Cr. castanece, and which must 

 be considered the type of his description, and which has not been 

 noticed by any other author ; 5, Cr. Mexicanus, Schaum. He 

 added, in conclusion, that the habits of the genus were very little 

 known ; that he had himself found one species in ants' nests on 

 the Catskill Mountains, and that Professor Haldemann had also 

 found two species in similar situations in Pennsylvania. 



Dr. Schaum also exhibited many new or very rare Coleoptera, 

 found by himself in his journey through the United States. 



Dr. Schaum next exhibited specimens of Glyptus subtilis, one 

 of the rarest of the Carabideous insects, which had been found in 

 Western Africa, by Dr. Savage, in the nests of the Termites, or 

 white ants; and a drawing of a remarkable Goliathus, existing in 

 the collection of Mr. Turner, of Manchester. This specimen, 

 which he considered to be a variety of Got. cacicus, has the head 

 and bands of the thorax almost white, the elytra almost white, 

 wanting the bluish silvery hue common in Gol. cacicus, and having 

 the humeral and apical black patches almost touching one ano- 

 ther ; thus seeming to form a link between Gol. Drurii and Gol. 

 cacicus. 



Mr. Westwood remarked, that after a very careful examination 

 of many specimens of both species, he could not indicate any
