Protomicroplitis xanthaspis (Ashmead) comb. n. 



Apanteles xanthaspis Ashmead, 1900 : 280. 



Microgaster xanthaspis (Ashmead) Muesebeck, 1920 : 28. 



$. Hind femur blackish. Tergite 1 yellow ; rest of body blackish. 



Face coarsely rugose-punctate. Occiput scooped out as far as the posterior ocelli. Vertex 

 and temples coarsely punctate. 



Mesoscutum dull, closely rugose-punctate all over. Disc of scutellum as dull and rugose as 

 the mesoscutum. Propodeum coarsely rugose and with well defined medial keel. Areolet 

 3-sided ; 1st abscissa of the discoideus as long as the 2nd ; vannal lobe with distinct fringe of 

 hairs throughout. 



Tergite 1 narrow, parallel-sided, about twice as long as wide and with complete longitudinal 

 groove. Tergite (2 + 3) with distinct but rather poorly defined median field that is slightly 

 wider in front than behind. Ovipositor sheath without apical setiform appendages. 



W. Indies : St. Vincent. (Type locality). 

 Type in the British Museum (Nat. Hist.). 



The following key introduces as new certain Philippine species and one from 

 Borneo that I have been able to separate from the other species of the group known 

 to me. How they stand in relation to these other species will be made clear in the 

 key itself. 



Key to Philippine Species 

 Females and Males 



1 Lateral sulci of tergite 2 strongly developed and each in the form of a deeply channelled 



groove that borders the edge of the tergite at least as far as the 2nd suture. 



Tergite 2 distinctly a little longer than 3, strongly modified, showing a narrow, 

 parallel-sided median field that is separated from the lateral surface of the tergite 

 by a broad, rugose furrow (Text-fig. 307) ; 2nd suture deep, strongly costate ; eyes 

 normal, slightly divergent above and separated from the posterior ocellus by a 

 distance distinctly greater than the longer diameter of the ocellus ; head red. 

 (pyrene-suh-gvoup, transitional between basimacula-group and typical xanthaspis- 

 group) 2 



- Lateral sulci of tergite 2 not thus strongly developed ; if marked at all, each extends 



only as far as the edge of the tergite and then fades out ..... 5 



2 Females ............. 3 



- Males 4 



3 Front and middle claws with a comb of fine, very close bristles ; mesoscutum and 



scutellum red ; hind femur infuscate at apex ; hind tibia blackened at extreme base 

 and on apical third ; hind coxa with a conspicuous black apical patch ; median field 

 of tergite 2 long, better defined ; the lateral areas of this tergite highly polished. 



Mesoscutum strongly shining, without surface sculpture, its sharp punctures at 

 least mid-posteriorly often separated by nearly one diameter ; tergite 1 at apex 

 with a deep, smooth pit, the sub-horizontal surface on each side of which is swollen 

 and smooth ; 2nd transverse cubitus meeting the 1st transverse cubitus far from 

 junction of the two radial abscissae (Text-fig. 310) .... pyrene sp. n. 



Philippines : Luzon, Mt. Makiling, 1 ?, the TYPE, 8 S3, {Baker) ; Los Banos, 

 1 $, (Baker). Type in the U.S. National Museum. 



The flagellum is long, thick, with the preapical segment fully twice as long as wide. 



- Front and middle claws simple ; mesoscutum blackened but with reddish suffusion 



posteriorly ; scutellum reddish ; hind femur entirely pale ; hind tibia with very faint 

 apical infuscation ; hind coxa with slight infuscation at apex above ; median field
