THE CANADIAN ENTOMOLOGIST. 121 



The dorsal surface of the abdomen of the male, as in C. pacificns 

 and C. henshmvi, to which this species is closely related, is not smooth as 

 in other species of Ceuthophilus, and like them also the fastigium of the 

 vertex is developed as a triangular prominence pushed between the 

 antennal scrobes. In the present species the roughnesses of the abdomen 

 are found from the third segment backward and consist of transverse 

 series of slightly elongated tubercles on the posterior margin of the 

 segments. 



17. CeiitJiophilus henshmvi Scudd. — It has been reported from 

 Vancouver Island, Washington, Oregon, and from Placer, Marin, Kern, 

 and Los Angeles Counties in California. It was taken at Tenino, Wash., 

 Sept. 24, by A. P. Morse. 



Hemiudeopsylla Sauss.-Pict. 

 This genus was founded primarily on a Mexican species, to which 

 three others, one from Mexico and two from central California were 

 added. I have been unable to identify the Californian species with any- 

 thing I have seen, but add them to the list. 



18. Hemiudeopsylla platyceps Sauss.-Pict. — Marin, Co., California. 



19. Hemiudeopsylla calif orniana Sauss.-Pict. — Marin Co. , California. 

 This was supposed by the authors to be my Ceuthophilus calif ornia7ius 

 (see above), but their description does not agree with my types, and the 

 specific name must be changed to a new one unless it belongs with some 

 previously described species, which I think improbable. 



Phrixocnemis Scudd. 



20. Phrixocfiemis validus Scudd.— California, H. Edwards. Known 

 hitherto by a single specimen only. 



Eudeopsylla Scudd. 



21. Eudeopsylla nigra Scudd. — A single specimen has been taken 

 in El Dorado Co., Ca)., 4,000 feet, by Gissler ; otherwise it is known only 

 from the region between the Mississippi Valley and the Rocky Mts., in 

 Manitoba, Minnesota, Dakota, Illinois, Iowa, Nebraska, Kansas, Missouri 

 and Colorado, though one specimen has been brought from Arizona. 



Gammarotettix Brunn. 



22. Gammarotettix bilobatus Thorn., sp. — This is known only from 

 central and southern California, having been taken in Lake, Sonoma, 

 Marin, San Mateo, Santa Clara, Los Angeles and San Diego Counties.
