REPORT OF THE STATE ENTOMOLOGIST I907 265 



Species which belong to the Ceratopogoninae but not sufficiently 

 characterized to place are : s o r d i d e 1 1 u s (belongs to Bezzia or 

 Johannseniella), b a s a 1 i s and o b s c u r u s (Palpomyia or 

 Bezzia), arctic'us and sequax (belong to Ceratopogon or 

 Johannseniella), albarius and d i m i d i a t u s (belong to 

 Johannseniella or Palpomyia), r u f u s and s u b a s p e r (belong 

 to Palpomyia or Heteromyia), and scutell-atus Say (wholly 

 indeterminate) . The species s t e n a m m a t u s and w h e e 1 e r i 

 are known only in the immature stages. 



Genus ceratopogon 



Meigen, 1803 ; Kieffer, 1899, 1906 



Meigen ( 1803) mentions barbicornis as the representative 

 of this genus. This was evidently an erroneous identification, since 

 in 1804 he placed it among unknown species and gave a compiled 

 description, followed by the remark that he was not certain whether 

 the species described under this name by Gmelin and Schrank was 

 the true barbicornis or whether they had mistaken his 

 Ceratopogon communis for it — thus apparently indicat- 

 ing that he had made the same mistake previously. It thus appears 

 that Meigen had communis in mind as the representative of 

 the genus and it must therefore be considered as the type. I am 

 indebted to Mr Coquillett for the quotation from Meigen (1804). 



Ceratopogon communis, though not a well known 

 species, belongs without doubt (as may be seen from Meigen's 

 description) to the genus Ceratopogon as now restricted, under the 

 subgenus Atrichopogon of Kieffer. 



The following North American species are referred to the genus

 to Culicoides. *ancorus, "^bellus, bipunctatus, 

 brumalis, *calcaratus, cilipes, "^'cinctipes,
