Family PTEROMALIDAE 

 Genus NEOCATOLACCUS Ashmead 



NEOCATOLACCUS MONEILEMAE. new species 



Similar in size, shape, and general appearance to N. tylodermae 

 Ashmead but distinguished at once by the partially carinate margin 

 of the pronotum, the much more delicate transverse carina on the 

 propodeum, and the much less conspicuous vestiture of the thorax, 

 the hairs being slenderer and nearly straight, not coarse and recurved 

 or recumbent as in tylodermae. 



Female. — Length 4 mm. Head strongly transverse, a little broader 

 than thorax at tegulae, strongly and nearly evenly alveolately sculp- 

 tured except the clypeal region, which is convergently striated; cly- 

 peus with distinct median sinus; right mandible quadridentate, the 

 left tridentate ; malar space equal to about half the eye height, malar 

 groove absent or very indistinct ; ocelli in a low triangle, the ocelloc- 

 ular line equal to a little more than twice the diameter of an ocellus; 

 antennae inserted at middle of head ; scape cylindrical ; pedicel about 

 twice as long as thick at apex; three very distinct transverse ring 

 joints; funicle 5- jointed, the first joint longer than pedicel and more 

 than twice as long as thick, following joints successively decreasing 

 in length, the fifth a little longer than thick; club 3-jointed, not 

 broader than the funicle and about equal in length to the two pre- 

 ceding funicle joints. Thorax sculptured like the head, moderately 

 robust; pronotum strongly transverse, sharply carinately margined 

 anteriorly at the middle, the carina fading out laterally before at- 

 taining the dorsolateral margins; mesoscutum much broader than 

 long with parapsidal grooves sharply impressed for about two-thirds 

 its length, absent posteriorly; scutellum about as broad as long, 

 rounded at apex, and immargined ; propodeum a little less than half 

 as long as scutellum, alveolately sculptured but the alveolae not 

 quite so deep as on scutellum and mesoscutum, with a distinct median 

 longitudinal carina, and a delicate more or less obscure and some- 

 what sinuous transverse fold extending across the middle and termi- 

 nating at the lateral folds, the latter represented anteriorly by a 

 large and moderately deep depression on each side about midway 

 between the spiracle and the median longitudinal carina ; mesopleura 

 sculptured like the mesonotum; metapleura and hmd coxae sculp- 

 tured about like propodeum; hind tibia with two spurs, the inner of 

 which is a little longer than the outer; forewings not reaching to 

 apex of abdomen, the stigmal vein a little less than half as long as 

 marginal, postmarginal equal to about two-thirds of marginal; 

 abdomen pointed ovate, distinctly longer than head and thorax, as 

 broad as thorax, the first tergite polished, following tergites weakly 

 lineolated and shining; ovipositor sheaths barely extending beyond
