characterized it as having- the ovipositor narrowed mesiallj" and nar- 

 rower than the fastiginni. The t3'pes were examined and the char- 

 acters are, in my opinion, not specific. The thoracic mottling and the 

 slight mesial narrowing of the ovipositor are not correlated, and the 

 male genitalia, while somewhat shrunken, seem to be just as in typical 

 carmata. 



Type. — In the Museum of Comparative Zoology. 



Spechnen.s exmiiined. — The National Museimi contains two adult 

 males, one female (hg. 8) and a n3'mph from Seattle, Washington; 

 one adult on September 20, the others without dates, and one female, 

 nymph from Humboldt County, California, June 1>; also a male from 

 Eureka, California. July 5, lUOG. 



NEDUBA CARINATA var. CONVEXA, new variety. 



Description, — Differing- from typical r((rinat<( in several particulars. 

 The size is somewhat greater as represented hy the three specimens 

 before me and the color seems lighter. The pronotum of the only 

 female seen (tig. 9) is more convex on the disk and is longitudinall}"

more convex than in an}" other specimens seen, that of the male 

 seemingly more distinctly rugose than common in carinata. The 

 lateral carinas of the pronotum of the female are more bowed outward 

 than in allied s])ecies, giving- it a slight superficial resemblance to 

 members of the preceding genus. The median carina is about the 

 same as in carinata. Prosternum armed with moderately long spines, 

 rather short in the male specimens. The ovipositor is longer than 

 usual in allied forms, l)ut when a number of specimens are examined 

 it will probabl}^ be found to vary as it does in typical carinata. The 

 infracercal plates of the male, while shaped essentially as those of the 

 typical form, are apparently ))roader, their combined wndth being 

 generally greater than that of the last abdominal segment, probably 

 due, however, to the greater relaxation of the genital organs of the 

 specimens examined rather than to the actual width. Last abdominal 

 segment of the male with the posteriolateral corners more produced 

 than in t3'pical carinata and the apical styles of the subgenital plate
