Ceratinostoma maritimum Meade, Ent. Monthly Mag., XXII, 152, 1885. 
This European species has not been recorded from North Amer- 
ica although it is quite generally distributed along the New 
England coast. I first received several specimens from Mr. S. A. 
Shaw, collected at Hampton Beach, N. H., May 24. Mr. Owen 
Bryant captured a specimen at Cohasset, Mass., September 9, and 
Dr. C. S. Minot a specimen at Northeast Harbor, Maine, July 4 
1909. On July 25, 1907, the writer obtained a number of specimens 
at Orr’s Island, Maine, on the wet rocks at low tide. A number 
were also obtained on the rocky shore at Shackford’s Head near 
Eastport, Maine, July 14, 1909. 
Mead refers to this genus as occupying an intermediate position 
between Scatophaga and Cordylura. “It has the elongated 
horny proboscis with the numerous vibrissz of the species in the 
former genus and the sub-cylindrical incurved clubbed male 
abdomen of those of the latter.” 
The species can be readily recognized by the following char- 
acters: Face white, front dark brown, antenne and proboscis 
black, palpi yellow. Thorax, abdomen and legs slate-gray in 
color, the former having three wide obscure stripes. Tegule and 
halteres yellow. Hairs and bristles noticeably shorter than in 
most of the Scatophagi. Length 8 mm. The synonomy is that 
given in the Katalog der Paliarktischen Dipteren, IV, 12.

Specimens agreeing with the description of this species (which 
proves to be a Scatophaga) are represented from the following 
localities: Mt. Washington, N. H., (Mrs. Slosson); Durham, 
N. H., July 17, 1905 (J. Randall); Buffalo, N. Y., October 25 (M. 
C. Van Duzee).
