HYMENOPTEROUS PARASITES. 1905 



yellowish, fiead finely punctate, somewhat polished; facial carina not well defined, 

 but terminating in front of antennae in a distinct polished tuljercle; mandililes red- 

 dish; palpi whitish, the basal joint of maxillary palpi black; eyes brown with paler 

 inner border ; antennae black in both sexes, scarcely as long as the body. Thorax: 

 scutellum polished, sparsely punctate; fovea of post-scutellum circular, occasion- 

 ally with a round, central granule; metascutum and metascutellum coarsely rugose, 

 the median carina on latter distinct, the lateral carinae straight, diverging ante, 

 riorly : tegulae blackish : wings hyaline, venation normal; the radial vein angulated; 

 costa, stigma and veins brownish black: logs, usually reddish with all coxae black 

 and the extreme base of the anterior and median and apex of posterior femora 

 more or less distinctly blackish ; all tarsi more or less dusky. Abdomen black, 

 laterally compressed beyond joint 3, and wedge-shaped; joint 2 and extreme base 

 3 rugose-punctate; joint 1 longer than broad, narrowest at base, broadening and almost 

 as broad posteriorly as 2 ; concavity at l)ase deep and not polished ; median carina of 

 joint 2 either very distinct or almost wanting; the otiier joints highly polished and 

 sparsely hairy ; flexible border of two basal joints rather narrow; venter black; the 

 ovipositor short, exserted, its slieatlis black. 



The J is distinguished by the longer antennae, by the less compressed abdomen, 

 by the palpi being dusky, the femora darker, tlie sides l)lack along the whole length, 

 the til)iae with a dusky tinge and the tarsi blackish. There is more variation in the 

 carina on abdominal joint 2, being l)ut feebly indicated in oue speciraeu and wanting in 

 a second. 



There is some variation in coloration, and one female, smaller than the 

 average, has the coloration of the male. 



The cocoons are white, less satiny than inflavicornis, somewhat stouter, 

 but similarly exposed and held together by loose silk. 



Described from 15 specimens (12 9 , 3 ^), bred by Mr. A. Koebele 

 from Lemonias anicia? from California. 



This species resembles A. limenitidis, var. flaviconchae which is readily 

 distinguished, however, by the want of median carina and facial tubercle, 

 but its coarser and more densely punctate mesoscutellum, the coarser sculp- 

 turing of the basal abdominal joints and by the normally shaped abdomen. 



9. Apanteles flavicornis n. sp. 



Parasitic on Thanaos juvenalis. 



Average length of body 2 mm. 5 : general color black ; pubescence quite dense, 

 short white. HeaO. : face without carina or tuliercle ; raandiljles honey -yellow ; palpi 

 white with the first joint of the maxillary palpi pale yellow; antennae brown above, 

 yellowish-brown beneath. Thorax : mesonotum without or rarely with an indication 

 of a carina; scutellum polished, without puuctation ; fovea of postscutellum very 

 small, divided by a minute median ridge; metascutellum rugose, its median carina dis- 

 tinct; tegulae yellow: wings with the costa, stigma and radial vein brown, the other 

 veins almost colorless : legs honey -yellow, the posterior coxae black; tip of posterior 

 femora, tibiae and tarsi often dusky. Abdomen black and honey-yellow; basal joint 

 somewhat longer than broad, narrowest at base ; together with second joint and more 

 or less of the base of the third, rugose-punctate; the second with a rather prominent 

 median carina ; the other joints polished ; the margins of joints 1 and 2, whole of 4 and 

 5 and generally the posterior margin and angles of 3 and sometimes more or less of 6 

 and the greater portion of the venter honey-yellow ; ovipositor very short, scarcely 

 exserted. 



J with the anteimae entirely yellow and the abdomen above generally black.
