compressed with a pale sharp carinate margin posteriorly, and bical- 

 carate ; abdomen about as long as head and thorax combined, broad- 

 est near apex, dorsal segments 4 and 5 always emarginate medially 

 and segments 2 and 3 sometimes emarginate, the last ventral segment 

 more or less prominent, ovipositor exserted. 



Male. — Resembles the male of Anastatus but may be distinguished 

 by the shorter postmarginal vein. Antennae 11-jointed; scape short, 

 third antennal joint ringlike, funicle joints cylindrical, thicker than 

 the pedicel, the club apparently solid and a little more slender than 

 the funicle joints; scrobes deeper than in the female, extending up- 

 ward nearly to front ocellus; eyes densely hairy, nearly circular; 

 mandibles 3-dentate; mesoscutum not depressed, parapsidal grooves 

 delicately impressed and complete; scutellum rounded behind, convex; 

 propodeum with a delicate median carina; wings without a cloud; 

 postmarginal vein a little longer than stigmal; middle tarsi not swol- 

 len, the tibial spur long and slender; hind tibiae compressed, club- 

 shaped; abdomen not longer than the thorax, subelliptical. Body 

 color metallic. 



Redescribed from the type of E. hrasiliensis Ashmead, a cotype of 

 E. proximus da Costa Lima and the types of the new species described 

 below. This genus is probably closest related to Lecaniobius Ash- 

 mead, but is readily distinguished by the shape of the head and the 

 shallow, poorly defined, antennal depression. The hind tibiae and 

 other characters ally it also \i^lth Metapelma Westwood from which 

 it is readily separated by the crest of hairs on the scutellum, the 

 separated axillae, and the proportionally much longer marginal and 

 much shorter postmarginal veins. 



KEY TO THE SPECIES OF ENCYRTASPIS. FEMALES 



1. Ovipositor sheaths slightly longer than the whole body, with a broad whitish 



band before the apex and a pale line beneath from base to the union with the 



band hrasiliensis Ashmead. 



Ovipositor sheaths not as long as the body 2. 



2. Mesoscutum bronzy black, not deeply concave at posterior middle, the lat- 



eral lobes not sharply carinate; axillae metallic; propodeum and hind coxae 

 more or less metallic; ovipositor sheaths with a yellowish band 



proximus da Costa Lima. 



Mesocutum uniformly rufo-testaceous, deeply concave at posterior 



middle, the lateral lobes high and sharply carinate posteriorly; axillae 



rufo-testaceous as are also the propodeum and hind coxae; ovipositor sheaths 



uniformly testaceous semirufus, new species. 



ENCYRTASPIS SEMIRUFUS, new species 



Female. — Length, 3 mm. Head nearly uniformly shagreened; 

 viewed from in front appearing a little longer than broad, the cheeks 

 rather long; eyes strongly diverging below, more than twice as far 

 apart at lower extremity as at vertex; viewed from the side the head
