Bericht iiber die wissenschaftliehen Lelstungen im Gebiete der Entomologie 

 wahrend der Jahre 1859 to 1866. (7 Parts) Von Dr. A. Gerstaecker. From the 

 Author. 



Dr. Houn made a few remarks concerning Cossyphus, a genus considered 

 from its tarsal characters as being a Tenebrionide ColeoiJteron, showing how- 

 ever a peculiarity of structure unknown until now, excepting among the Ehyn- 

 chophora. The character was first observed by Dr. LeConte in the latter group 

 of families, and its systematic value pointed out before the National Academy 

 a year or two ago, and consists in the union of the edges of the pros- 

 ternal epimera on the median line behind the presternum, so that 

 [\/| i the latier never attains the margin of prothoracic segment, and is 

 consequently never near the mesosternum. The accompanying il- 

 lustration exhibits this peculiar structure in Cossyphus, which ajjpears to indi- 

 cate the possibility of the removal of the genus from its present position to the 

 head of the great Rhynchojihorous section of Coleoj^tera. 



Dr. LeConte followed in remarks regarding the interest of the observation 

 here made known, and exj)lained at some length the peculiarities of structure 

 of the under surface of the prothorax in the different families of Ooleoptera. ,
