ART. 14 THIRTEEN NEW ICHNEUMON-FLIES CUSHMAN 7 



and others having the thorax entirely black except the scuteHum and 

 faint indications of red on subalar tubercles and before middle coxae. 

 The scutellum in the female is sometimes virtually black. 



Known only from New Jersey and Pennsylvania and only as a 

 parasite of an introduced insect, this species may possibly have been 

 introduced with its host, but I have been unable to identify it as any 

 of the described Japanese or European species of Ephialtes or 

 PimpJa. 



EIPHOSOMA AZTECUM Cresson 



Both Brues ^ and Cockerell ^ misplaced this species in their keys 

 among those species with lateral black markings on the propodeum. 

 The " spot on the flanks " of Cresson's description is on the meso- 

 pleurum, and the " lateral stripes on mesothorax " are those on the 

 lateral lobes of the mesoscutum. In both of the above keys, a cotype of 

 aztecuiii in the National Museum collection runs to seytentrionale 

 Brues, from which its polished and impunctate (except on meso- 

 scutum) thorax and propodeum, entirely red hind femur, and longer 

 malar space will serve to distinguish it. 



EIPHOSOMA PARAGUAIENSE, new species 



Runs in both Brucs's and Cockerell's keys to the last couplet, but 

 agrees w^th neither alternate. From cbztemmi Cresson, which, as 

 pointed out elsewhere, is misplaced in both keys, it differs in having 

 the lateral black markings on the propodeum and in the extensive 

 black coloration of the hind femur. From atrovittatumi Cresson it 

 differs in its black hind tibia and tarsus; and from forte Cockerell, 

 in its much smaller size and hyaline wings. From all three it differs 

 in its lack of the areolet. 



Female. — Length, 11 mm.; antennae, 9 mm.; ovipositor, 5 mm. 

 Face coarsely punctate, clypeus more sparsely so, both somewhat ele- 

 vated; frons transversely striate; temples shagreened; malar space 

 barely half as long as basal width of mandible and narrower than 

 cheek; lower portion of occipital carina and especially lower margin 

 of mandible strongly elevated and flangelike; eyes very large and 

 bulging slightly beyond the general contour of the head; antennae 

 slender, basal joint of flagellum fully six times as long as thick. 

 Thorax shining, mesoscutum, mesosternum, and lower pleurum 

 sparsely punctate; propodeum without longitudinal carinae but 

 strongly separated from the metapleurum, obscurely, transversely 

 striate, more distinctly so in the broad, shallow, median impression; 

 areolet wanting; postnervulus broken slightly above upper third; ner- 

 vulus interstitial; abscissula curved, strongly oblique to metacarpella 

 and hardly half as long as intercubitella ; nervellus slightly inclivous.
