here ; hind tarsus unusually long and thin, about one and half times longer than 

 the hind tibia. 



Metacarp slightly shorter than in ariovistus. Malaya . . solox sp. n. (p. 97) 



Apanteles cavifrons sp. n. 



o* ?. Hind femur dull brownish red with the hind tibia reddish on basal two thirds but 

 becoming as dark apically as the femur. 



$. Vertex between the posterior ocellus and the eye-margin shining and almost smooth. 

 Eyes fairly strongly convergent, as in lyridice (cf. Text-fig. 27). Antenna about as long as the 

 body with segment 17 fully one and one third times longer than wide. 



Mesoscutum dull, coarsely punctate ; posterior end of notaulic course virtually without 

 longitudinal elements. Scutellum closely, almost coarsely punctate. Areolation of the 

 propodeum very strong. Setae of the medial cell dense, brown ; metacarp at least six times 

 longer than its distance from the apex of the radial cell, almost closing the radial cell. Hind 

 coxa shiny, almost smooth. 



Median field of tergite (2 + 3) angled laterally at about 30 degrees. Ovipositor sheath slightly 

 shorter than the hind tibia. 



Length: ca. 3-3 mm. without ovipositor. 



Philippines : Los Bafios, 8 $$, one the TYPE, 8 <$<$ ; Luzon, Mt. Makiling, 

 1 $, 1 (J. (All Baker). 

 Type in the U.S. National Museum. 



A most distinct species on account of the structure of the frons ; in no other 

 species of Apanteles have I met with such an excavation. 



Apanteles opacus (Ashmead) 



Urogaster opacus Ashmead, 1905 : 118. 



Apanteles opacus (Ashmead) Wilkinson, 1928a : 128. 



$. Tergite (2 + 3) darkened all over (Philippines) but sometimes markedly yellow (Sandakan, 

 India, Buitenzorg, I. of Penang, Japan). Only basal quarter of hind femur yellow in specimens 

 from Philippines ; more than half yellow (India and Japan) and almost entirely yellow in a single 

 female from I. of Penang. 



Face shining and only with very superficial punctation. 



Mesoscutum rather shiny in spite of its strong punctation ; course of notaulices showing as a 

 coarsely rugose band that posteriorly widens into an area of conspicuous striate-punctation. Disc 

 of scutellum shiny and covered with ill defined pits. Hind wing decidedly narrow ; stigma less 

 elongate than in cavifrons. 



Hairy part of ovipositor sheath about three quarters as long as the hind tibia. 



Length: 3 mm. without ovipositor. 



Philippines : Los Bafios ; Luzon, Mt. Makiling & Mt. Limay ; Mindanao, 

 Surigao ; Davao ; Manila. Malaya : I. of Penang. Japan : Kobe. 24 $9- (AH 

 coll. Baker). India : United Provinces, Dehra Dun, x.1935, 3 $$, bred from 



Pachyzancla stultalis ; Mysore, Bangalore, 1 $, bred from Pericallia ricini. Java : 

 Buitenzorg, 1 <j>, bred from larva on Amaranthus. 

 Type in U.S. National Museum. 



Host : Pachyzancla stultalis Walker (Pyralidae) ; Pericallia ricini F. (Arctiidae). 



In general appearance this species is exactly like cavifrons.
