ENTOMOLOGICAL SECTION. 



Daring the progress of the " Genera" Dr. LeConte, with a com- 

 mendable liberality, sent to Lacordaire for study a number of types 

 of genera, and in particular many from California, among which 

 were several uniques, namely, Acreph maculata, Craniotus jmbescens, 

 Oryptadius mflatus and Auckmobim subkevis. By an unfortunate 

 calamity the vessel conveying them never reached Euro])e, and the 

 specimens were lost ; the types of Schonherr's Curculionidac were 

 near meeting a similar fate some years later. Two of the lost species 

 were recovered dui'ing my travels in the West, the third is due to 

 Ci'otch, while it is now, after more than thirty years, a pleasure to 

 add the fourth.
