scribed. It is probably more closely allied to the species here de- 

 scribed as j)runi. The original description is as follows : 



" Mesonotum and collar black ; body black, with legs beyond femora 

 white; third segment of antennae shorter than fourth; clypeus dis- 

 tinctly emarginate ; median fovea large, shallow, circular ; Avings in- 

 fuscated on basal half. Length 6 mm," 



In a letter dated January 13, 1919, Doctor MacGillivray says: 

 " The type of Craterocercus infuscatus was collected at Ithaca, New 

 York, and is without date. The specimen is a female."

In his latest paper ^'' MacGillivray leaves this species in the genus 

 PHophorus, According to our opinion, it does not belong to this sub- 

 family. The basal vein, which joins the subcosta remote from the 

 origin of the cubitus (see fig. 8), the larvae and their habits are im- 

 portant characters which show that the species is Nematine. This 

 species, according to our opinion, is generically different from Prio- 

 phornis, and the genus Caulocampus, of which it is the genotype, 

 should be placed in the Nematine, tribe Hemichorini.
