Morphological characteristics of spiracles, body (pi. 13, fig. 1), 

 and legs do not vary from Ritcher's description. 



The single unassociated larva which Ritcher described was collected 

 at Dover, Del., October-November 1941. Ritcher beheved it was 

 probably the larva of Bolbocerosoma tumefactum as it is the common 

 species in that area. However, the larva upon which Ritcher based 

 his description was compared with the Faison specimen of B. farctum 

 and was found to be almost identical. The few differences noted, with 

 the possible exception of the truncate labrum, could very easily be 

 normal variation within a species. In Bolboceras (and perhaps 

 Eucanthus) the laiown larvae show a number of interspecific differ- 

 ences, and I would suspect this to be true in Bolbocerosoma. Certainly, 

 more information is needed concerning the larvae of this interesting 

 group.
