NOTES ON SAWFLIES, WITH DESCRIPTIONS OF NEW 

 GENERA AND SPECIES. 



By S. A. Rohwer, 



Custodian of Eymenoptera, United States National Museum. 



The types of most of the new species here described are in the 

 collection of the United States National Museum. A few, however, 

 are in the collections of other institutions which have forwarded 

 the material to the author at his request and on the condition that 

 the types be returned to them. 



Suborder IDIOGASTRA. 



STIROCORSIA KOHLI Konow. 



A single male collected at Sandakan, Borneo, by C. F. Baker agrees 

 fairly well with the description of the female given by Konow and is, 

 I believe, the male of his species. 



Length, 8 mm. Anterior trochanters and hind tibiae dark piceous; 

 ventral sternite produced into a rather narrow truncate process 

 apically, the ventral surface with six tubercules arranged so as to 

 form a semicircle. 



Suborder CHALASTOGASTRA. 

 Family XIPHYDRIIDAE. 



XIPHYDRIA ABDOMINALIS Say. 



Xiphydria abdominalis Say, Keating's Narr. Exped. appendix, vol. 2, 1824, 

 p. 311; LeConte's Writings of Say, vol. 2, 1859, p. 208. 



In my synopsis of the Nearctic species of [Xiphydria l I con- 

 sidered this species to be the same as attenuate/, Norton and rufiventris 

 Cresson, and made a specimen from Harrisburg, Pennsylvania, a 

 neotype for Say's species. A single female specimen collected at 

 Charter Oak, Pennsylvania, June 19, 1918, by H. B. Kirk, proves 

 that this interpretation for the species is incorrect and that the 

 specimen chosen as a neotype can not justly be considered as such.
