ACANTHOCHALCIS UNISPINOSA, new species. 



Female. — Length, 18.00 mm. 



The same as the genotype but the propodeum bears a short, stout 

 tooth at meson near base while from lateral aspect the flattened 

 lateral part of the propodeum does not project over the caudal 

 metapleurum. Funicle 1 thrice longer than wide (nearly thrice 

 longer than wide in the other) ; the propodeum bears a median carina 

 (three rugae in the other at meson). Forewings smoky in both, the 

 venation black, the postmarginal vein longer than the marginal. 

 Hind wings clouded distad. Femoral furrows deep (for first and 

 second legs). Abdomen with no conspicuous patches of pubescence, 

 nor the hind coxae nor the subdued prominence on the propodeum 

 while the scutellum at distal half is obtusely biparted by a deep, 

 obtuse median "valley." 



One female in the United States National Museum, Texas (Belfrage). 



Type. — Cat. No. 20752, U.S.N.M., the female on a pin and antennae 

 on a slide. 



DBPLODONTIA SECUNDA, new species. 



Female. — Length, 6.50 mm. 



Yellow, the wings infuscated but lighter toward the tip, the body 

 marked with black as follows: Antennae except the buUa and ventral 

 aspect of scape (also lower sides near base), upper half of occiput 

 except eye margin, the black continuing over the vertex and down the 

 face to the antennae (the eye margin more broadly yeUow on the 

 face, the ocelli lined with yellow mesal) the upper face of pronotum, 

 pronotum except cephalic margin and broadly mesad (where it is 

 a mere line), the propleurum except cephalic margin and ventral 

 half, scutum except lateral margins narrowly except at each end, 

 parapsides except lateral margin (more broadly cephalad), mesal 

 haK of axillae, a broad median stripe two-thirds of the way down the 

 scuteUum, propodeum except the spines and the convex protuberance 

 and plate near the hind wings, mesopleurum, ventral haK of meta- 

 pleurum, meso- and meta-venter, hind coxae except a large fusiform 

 area from base (basal dorso-laterad, a large hooklike marking on 

 hind femur, inner aspect, from apex to beyond middle (along the 

 lower side) a large comma-shaped marking on same, lateral aspect, 

 about middle, its pointed end not reaching tooth 4; base of hind 

 tibia; a dot, each side, apex of petiole; a V-shaped marking base of 

 segment 2 nearly to its apex; five narrow cross stripes, 1-2 most 

 distinct, 1 near apex of segment 2, 2 about the middle. Postmarginal 

 vein somewhat shorter than the marginal. Tooth 6 of hind femur 

 broadest, serrulate. Antennae 13-jointed. Funicle 1 a half longer 

 than wide; propodeum foveate. Pubescence fuzzy. Abdomen normal, 

 the pedicel nearly twice longer than wide.
