U. S. NATIONAL MUSEUM. 



Prof. Charles P. Loundsbury, Government Entomologist, of Cape 

 Town, South Africa, has recently sent to Dr. L. O. Howard, U. S. 

 Entomologist, a lot of bred parasitic Hymenoptera for names, among 

 which were found three new species, which, at the request of Dr. Howard, 

 are characterized below : 



Family LVII. — Platygasterid^. 



Genus Allotropa, Forster. 



(i) Allotropa Loundsbury i, new species. 



$ . — Length, 0.9 mm. Polished black ; antennae and legs mostly 

 brown or brown-black, the base of the scape, pedicel, funicle joints 1 to 4, 

 trochanters, knees, base of tibiae, the tarsi except last joint, and the 

 petiole of abdomen, yellow. Wings hyaline, entirely veinless, except the 

 subcostal vein which terminates in a small knob. 



The antennae are 8- or 9-jointed, depending upon whether the 

 enlarged antepenultimate joint is counted as a single joint or as two 

 closely-united joints ; funicle joints 1 to 4 much slenderer than the 

 pedicel or joints 5 and 6 of funicle, the first joint being not quite twice as 

 long as thick, the second shorter, the first and fourth subequal, sub- 

 quadrate. The abdomen elongate, conically pointed, about one-third 

 longer than the head and thorax united, the petiole very short, wider than 

 long, while the second segment is large and occupies about half of the 

 whole surface of the abdomen. 



<$ . — Length, about 0.8 mm. Agrees well in colour with the female, 

 but differs in having the antennae distinctly 9-jointed, the joints being 

 distinctly separated, the fiagellum filiform, the joints oblong, with whorls 

 of sparse long hairs, while the abdomen is oblong oval, not pointed at 

 apex and not longer than the thorax. 



Type.— Cat. No. 5727, U. S. N. M. 



Hab. — Cape Colony, South Africa. 



Host. — Rhynch. : Dactylopius sp. on Gorse. 



Bred by Prof. ("has. P. Loundsbury, Oct. 22, 1898.
