[159] HYMENOPTERA 165 



The head and thorax above are sparsely punctate, the pleura being 

 rugulosely punctate, the metathorax more strongly rugulose, the 

 wrinkles in the areas, and particularly in the petiolar area, which is 

 very long, being transverse ; the areola is horse-hoof shaped, the basal 

 lateral and the median lateral areas being confluent. The abdomen is 

 fully twice and sometimes more than twice longer than the thorax ; 

 the petiole is punctate and somewhat aciculate to slightly beyond the 

 spiracle, the surface beyond being smooth or only faintly punctate; 

 dorsal segments 2 and 3 alutaceous and also punctate, the punctuation 

 of the second being more distinct and somewhat rugulose basally, the 

 segments beyond smooth, impunctate. 



Type. Cat. No. 5544, U. S. Nat. Museum. From Yakutat, June 

 21 ; Orca, June 26. Several specimens. 



This species mimics the male of Ichneumon brevipennis Cresson in 

 color, and the metathoracic characters must be closely scrutinized or it 

 may be easily confounded with it. 



CRATICHNEUMON POPOFENSIS sp. nov. 



Female. Length 7 mm. Ferruginous ; a frontal spot above an- 

 tennae, stemmaticum, occiput, prosternum, thoracic sutures, the trans- 

 verse depression of the prothorax and metathorax entirely and base of 

 petiole, black ; flagellum brown black, with joints 8 to 1 1 more or 

 less whitish or pale yellowish ; palpi white ; apex of hind tibia and 

 more or less of hind tarsi, fuscous. 



Stature similar to Ichneumon brevipennis Cresson, the head sub- 

 quadrate, the antennae stout, 26-jointed, the joints of the flagellum after 

 the fourth, transverse, the first only about twice as long as thick, joints 

 2 to 4 gradually shortening, the fourth not longer than thick. Thorax 

 smooth, sparsely punctate, the metathorax rugulose, the areola large, 

 nearly horse-hoof shaped, the anterior lateral angles being obtuse, the 

 basal lateral and middle lateral areas being confluent. The abdomen 

 is hardly one and a half times as long as the head and thorax united ; 

 the petiole, except at apex, is finely rugulose, the second and third seg- 

 ments alutaceous and punctate, the punctures on the third being shal- 

 lower and more sparsely distributed, the following segments being 

 smooth, impunctate, the gastrocoeli shallow and poorly defined ; ovi- 

 positor subexserted, the sheaths black. 



Male. Agrees well with the female, except that the metathorax 

 is ferruginous, except along the pectus, the flagellum being black above, 

 ferruginous beneath, 'without an annulus, while the apices of coxae,
