94. APANTELES CAFFREYI. new species. 



Very close to nigricor-nis ; the striking cocoons of the two species 

 are almost identical. The adult differs in the shorter antennae, in 

 the pale tegulae, in the radius being longer than transverse cubitus, 

 and in the first abdominal tergite not narrowing gradually from base 

 to apex. 



Female. — Length, 2.2 mm. Face slightly broader than long, 

 weakly punctate; vertex, temples, and cheeks punctate and opaque; 

 mesoscutum punctate, more weakly so posteriorly ; disk of scutcllum 

 slightly convex, about as broad at base as long, indistinctly punctate, 

 and not strongly shining; mesopleura punctate anteriorly, polished 

 behind; propodeum weakly punctate, with a few radiating striulae 

 arising at the middle of the posterior margin, and extending for- 

 ward; propodeal areola wanting; metacarpus distinctly longer than 

 the stigma and the radius longer than the transverse cubitus; ner- 

 vellus slightly curved behind toward base of wing; posterior coxae 

 smooth and polished, with a narrow flattened area on outer upper 

 edge at base ; inner spur of posterior tibiae slightly longer than the 

 outer and at least half as long as the metatarsus; abdomen slender; 

 first tergite very narrow and much narrower at apex than at base, 

 two and one-half times as long as broad at base, and perfectly smooth 

 and polished; second tergite triangular, defined laterally by sharp 

 oblique grooves, less than half as broad at base as long, and about 

 as broad at apex as long; the second tergite, like the remainder of 

 the abdomen, entirely smooth and polished; lateral membranous 

 margins along the apical third of the first tergite and the entire 

 length of the second, very broad; ovipositor subexserted. Black; 

 antennae black, except the scape, which is reddish beneath; tegulae 

 and wing bases pale testaceous; wings hyaline, the stigma and veins 

 pale brown; legs yellowish, except all coxae, which are black, and 

 the apex of the posterior femora and of posterior tibiae, and most 

 of the posterior tarsi, which are dusky; the lateral membranous 

 margins on the two basal abdominal tergites pale testaceous, this 

 color extending along the sides of the third tergite as well. 



Male. — Differs from the female only in the usual sexual characters. 



Cocoons. — Dark brownish-gray, covered with threads of pale gray 

 silk; gregarious and cemented together, but not embedded in silk. 



Type locality. — Tempe, Arizona.
