1 9, Pullman, Wash., 30, June, 1898 (C. V. Piper) "Reared 

 from Clisiocampa plumalis." This specimen is imperfect, 

 having lost the abdomen and may not belong here. 



Cockerell captured specimens of this species on rose hips 

 in Arizona and suggested that they may possibly breed in them. 

 I have reared this species abundantly from rose seeds from 

 Ithaca, White Church, and Wellsville, N. Y., Waukegan, 111., 

 Durham, N. H. (Charles Spooner), Boston, Mass. (Ralph 

 Curtis), Provo, Utah (R. V. Chamberlin), and Newark, Del. 

 (C. O. Houghton). Professor J. G. Sanders sent me specimens 

 reared from the seeds of Rosa rugosa, at Madison, Wis. Mr. 

 Nathan Banks has sent me 9 specimens reared from rose hips 

 at Falls Church, Va. 



Some of these localities are listed under M. aculeatus in 

 Cornell Exp. Sta. Bull. 265 because at that time I had not 

 separated these iwo species. It is probable that nigrovarie gains 

 is the native American species infesting rose seeds and that 

 aculeatus has been introduced recently, since I have reared it 

 from material collected at Ithaca only.

Female. — Length, 4 to 5 mm. ; abdomen, 2.3 mm. ; ovipositor, 5 to 

 5.5 mm. 



Vertex and occiput black; face, cheeks and a ring around eye 

 yellow, the latter broadly interrupted by the black of the vertex which 

 attains the eye-margin below the level of the front ocellus; antennal 

 furrows black; below the insertion of the antennee there is a circular 

 area cut off from the rest of the face by two or four brownish spots, 

 very variable in shape and distinctness; hairs on the face light colored, 

 above the base of antennae, brown. Vertex and front transversely 

 rugulose; cheeks and lower part of occiput smooth; face with lines 

 radiating from the clypeus. 



Prothorax black, with the sides and a large posterior dorsal band 

 greenish yellow; this band is usually biconvex in front. Mesothorax 

 black with an oblong reddish orange area covering the posterior half of 

 the middle lobe, the inner angles of the scapulce and axillae and all of 

 the scutellum. In some small specimens this orange area is obscured 

 by blackish in the center. Sculpture of mesonotum distinctly trans- 

 versely rugulose. Scutellum with the transverse stria distinct. Pleuree 

 black, scapulae have a large greenish yellow spot in front of tegulee. 

 Postscutellum black with a transverse rfiedian band of light yellow. 

 Propodeum black, irregularly rugose with a delicate median carina.
