ART. 25 NEW ICHNEUMON-FLIES CUSHMAN H 



to the ocell-ocular line and the malar space is very slightly shorter 

 than basal width of mandible. 



In both sexes the stigma is broadly pale along its anterior margin. 



CREMASTUS CARPOCAPSAE, new species 



Very closely related to C. gracilipes Cushman, from which the 

 female is distinguished with difficulty, though the male is quite 

 obviously distinct. 



Female. — Differs from gracili'pes apparently only in the uniformly 

 brown stigma ; the slightly broader abdomen, the second tergite being 

 hardly four times as long as broad at base; the slightly larger ocelli, 

 the diameter of which is fully as long as the ocell-ocular line; and 

 the shorter malar space, which is only about two-thirds as long as 

 the basal width of mandible. 



Color varying as in gracilipes as described above with hind femora 

 in the dark form somewhat infuscate. 



Male. — Kuns to couplet 3 in my key ^ as does gracili'pes male. 

 From gracilipes it differs principally by having the malar space 

 hardly two-thirds as long as the basal width of mandible, the diam- 

 eter of a lateral ocellus much longer than ocell-ocular line, the ab- 

 domen broader, the stigma uniformly colored, and the hind legs 

 infuscate. 



Host. — Garyocapsa pomonella (Linnaeus). 



Type loccdity. — Lawrence County, Ohio. 



Type.— C^t. No. 41995, U.S.N.M. 



Seven females and two males in rather poor condition received 

 from L. A. Stearns and reared by him August 4 to September 9, 1927. 



CREMASTUS (ZALEPTOPYGUS) HARTII Ashmead (new combination) 



Through the kindness of Dr. T. H. Frison, of the Illinois State 

 Natural History Survey, in bringing them to Washington I have 

 been able to examine the types of this species. Both sexes run in my 

 key to tetralophae Cushman, but differ as follows : 



Female. — Length 6 mm., antennae 4 mm., ovipositor sheath 2 mm.. 



Eyes barely as long as width of face, very slightly divergent be- 

 low ; malar space subequal to basal width of mandible ; f oveo-ocular 

 line distinctly more than half as long as interf oveal line ; diameter of 

 ocellus much shorter than ocell-ocular line; thorax more slender, 

 propodeum longer and less steeply sloping; pronotum laterally 

 shagreened but not punctate; mesoscutum less distinctly punctate, 

 notauli shallow; scutellar carinae obsolete except at base; meso- 

 pleurum not striate above, punctation very fine ; radius only slightly
