THE GENUS MONODONTOMERUS — GAHAN 469 



distinctly sculp ttired, a little more weakly so medially than lateral^; 

 postsciitelkmi distinctly finely sculptured; pleuron, except mesepi- 

 meron, strongly punctate; mesepimeron mostly smooth. Propodeimi 

 about 'half as long as scutellum, densely clothed with long white 

 hairs laterad of sph-acular sulci, bare medially; spiracular sulci 

 broad and foveated; propodeum medially with a deep, triangular 

 depression divided in the middle by a longitudinal carina, this depres- 

 sion broadest anteriorly, extending from base nearly to apex of propo- 

 deum and often more or less weakly foveated; surface of propodeum 

 between median depression and spiracular sulci distmctly reticulated. 

 All coxae and femora strongly sculptured; posterior femur with 

 ventral tooth a little longer and slenderer than usual. 



Anterior wing a little more than two and one-half tunes as long as 

 broad, reachmg nearly to apex of ovipositor; submargmal, marginal 

 postmargmal, and stigmal vems approxunately m the proportions of 

 70, 36, 16, and 10, respectively; basal cell completely outlmed by 

 distmci rows of hairs and with several additional hairs within the 

 cell; cilia on disk of wing moderately dense; marginal cilia very short. 

 Posterior wing reachmg to apex of abdomen. 



Abdomen about as long as thorax, distinctly shagreened on sides 

 and beneath; first segment dorsally perfectly smooth and constituting 

 approximately one-third total length of abdomen; second segment 

 dorsally very famtly transversely aciculated and about one-fifth as 

 long as first; third and fourth segments dorsally distinctly trans- 

 versely aciculated, the third three or four times as long as the second, 

 the fourth sUghtly shorter than thnd; fifth, sixth, and seventh seg- 

 ments short, together about equal in length to the fourth. Ovipositor 

 exserted about two-thu^ds length of abdomen. 



Male.— Length 2.8 mm. Differs from female only in the usual 

 sexual characters and in its smaller size. 

 Tyjye locality.— J ncBla, Hidalgo, Mexico. 

 Type.—V.S.^.M. No. 54263. 



Described from 20 females (1 holotype) and 7 males reared May 

 25 to 28, 1939, from cocoons of Trypoxylon mexicanum Saussure col- 

 lected at Jacala, Hidalgo, Mexico, by Phil Rau and bearing his note 

 numbers 1477 and 1506. 



6. MONODONTOMERUS INDISCRETUS, new species 



Female.— Length 3.3 mm.; ovipositor 1.1 mm. This species 

 apparently can be distinguished from mexicanus only by the fact that 

 the dorsum of the thorax is blackish green with only very slight 

 brassy reflections, the thorax appears to be slightly more slender and 

 a little less conspicuously hairy, and the hmd femur is apparently not 

 quite so broad.
