from Plagioincnis Crawford in lacking the scutellar hair clusters. 

 The frons is not prominent. 



I. Parahomalopoda peruviensis new species. Genotype. 



Female. — Length, 1.15 mm. excluding the ovipositor which is a little 

 over a fourth of the length of the abdomen. Dark metallic green, the wings 

 hyaline but infuscated slightly under the marginal and stigmal veins, the 

 venation duslcy yellowish. Antennae yellow suffused with dusky, the pedicel 

 dusky except at tip. Tarsi white except the last joint, also the base and 

 distal third of caudal tibiae, middle knees broadly, middle tibiae excepting a 

 broad cinctus a short distance out from base. Axillae slightly separated. 

 Funicles three and four subequal, large, a little longer than wide, one and 

 two subequal, each a half shorter than three or four. Club wider and a little 

 longer than the funicle. Marginal vein thrice longer than wide. Pedicel 

 nearly twice longer than wide. Body scaly. 



From one female in the U. S. N. M., on a slide labelled 

 " 1144° 3a. Gn. I. Sp. 2. Corcomba, May 17, 1910 — Townsend." Peru. 



Type. — Catalogue No. 19403, U. S. N. M., the above specimen. 



In Pscudhomalopoda prima the scape is dilated convexly distad. 

 The above species differs from Plagiomerus diaspidis Crawford only 

 in having a fuscous patch under the marginal vein and the scaly 

 sculpture of the thorax is finer. In Plagiomerus there is a smaller, 

 second hair cluster, one on each side of the mesal one. 



PSEUDHOMALOPODA new genus. 



Female. — Differs from Homalopoda in having the antennas sliort 

 and thick, the scape with a small convex dilation ventrad at apex, the 

 funicle joints all much wider than long, the pedicel and funicle sub- 

 compressed. 



I. Pseudhomalopoda prima new species. Genotype. Female. 



Length, i.oo mm. 



Differs from the genotype of Homalopoda- in having the middle tibia 

 except at base golden yellow, the ovipositor is not shortly extruded as in 

 that species and the wings bear the following different pattern : The large 

 naked hyaline area just cephalad of the venation is larger, larger than the 

 one farther distad of it (along cephalic margin), the latter cone-shaped (not 

 crescentic as in the genotype) with the smallest end at the cephalic margin, 

 this end narrow ; on the caudal half of the wing there are not three spots 

 as in the genotype but only two (the proximal one largest, both paired with 

 the two cephalic spots) and these are larger than the corresponding two in 

 the other species (which bears an additional spot farther proximad near
