NEW GENERA OF CHALCIDOID HYMENOPTERA. 



By a. a. Girault, 

 Washington, D. C. 



HOLANUSOMYIA new genus. 

 Female. — Belongs to the Ectromini. In my table of the earth's 

 genera runs to Holamisia but the stigmal vein is elongate, somewhat 

 over twice the length of the marginal, the postmarginal short, two 

 thirds the length of the marginal, the latter nearly thrice longer than 

 wide. Scape with its dilation broadening distad, the club a little 

 over half the length of the funicle. Face inflexed, the frons not 

 prominent, moderately broad. Eyes longer than the cheeks. Axillae 

 narrowly joined. Pronotum transverse-linear, the scutum large. 



I. Holanusomyia pulchripennis new species. Genotype. 

 Female. — Length, 2.00 mm. 



Dark metallic purple, the legs brownish yellow except the coxae, the 

 mesopleurum suffused with yellow, also the head ; scape, pedicel and funicle 

 one dusky pallid (funicle one white along one side), funicles two and three 

 white, the rest black. Pedicel somewhat longer than wide, shorter than 

 funicle one which is a half longer than wide, the distal three funicle joints 

 wider than long, three subquadrate. Head and thorax finely scaly. Cephalic 

 femora compressed. Fore wing with the following remarkable markings — An 

 oblique, conspicuous black band across not far from the tip (with a crenulate 

 distal margin) ; another clearer, rainbow-shaped stripe across from the mar- 

 ginal vein (running along the proximal edge of the stigmal vein), cephalad 

 running along the submarginal vein (for about the length of the stigmal 

 vein) to the base of the third, oblique (but oblique in an opposite direction — 

 caudo-proximad), shorter and thicker cross-stripe but which abruptly fades 

 near the caudal margin. The two proximal stripes form an inverted V with 

 one arm only half the length of the other and the apex broad not acute. 



Described from one female on a slide in the U. S. N. M. labelled 

 " From No. 23. Reared from P. citri on Bamboo, Manila, P. I., July, 

 '09. Compere." 



Type. — Catalogue No. 19384, U. S. N. M., the female on a slide. 



MERISUS Walker. 



Female. — Similar to Apirene of the Miscogasterid?e but the form is 

 more slender and the solid antennal club terminates in a more distinct 

 spine.
