the eye and arranged in a low triangle; front ocellus above the an- 

 tennal groove; viewed from in front the head is broader than high, 

 antennae inserted a little below the lower extremities of the eyes, 

 widely separated at base, the antennal grooves deep and carinately 

 margined, converging above but not confluent being separated above 

 by a sharp carina; lateral margins of the antennal grooves higher 

 than the inner margins and forming, laterad of the antennal fossae, 

 a prominent ledge which curves outward to meet the eye-margin at 

 or near the lower extremity of eye ; scape reaching to the front ocellus, 

 curved: flagellum gradually increasing in thickness from pedicel to 

 club; the club obliquely truncate; eyes moderately large, and very 

 faintly pubescent; mandibles tridentate; mesoscutum concave behind, 

 the lateral lobes longitudinally carinate posteriorly; axillae narrowly 

 separated; scutellum convex, rounded behind with a distinct median 

 longitudinal crest of black bristles; marginal vein shorter than the 

 submarginal; stigmal and postmarginal subequal and each approxi- 

 mately one-third as long as marginal; disk of forewing densely cili- 

 ated with a transverse fuscous band ; front femora distinctly swollen, 

 subtriangular in outline, broadest between middle and apex ; middle 

 femora broad, concave beneath : middle tarsi moderately swollen and 

 spined beneath; hind femora not much swollen, their tibiae com- 

 pressed into a sharp carina behind and bicalcarate; abdomen ovate, 

 not longer than the thorax, the tergites not incised at apex and the 

 ovipositor not or barely exserted. 



Male. — Unknown. 



The above generic description is drawn from the Ashmead and 

 Crawford types and the new species described below. Only two 

 species are known, cockerelU Ashmead and the new species. Both 

 species are, so far as known, neotropical in distribution. Crawford^ 

 has already pointed out that his species, Zalophothrix mi7mm, is a 

 synonym of Lecaniobius cockerelU Ashmead. 



LECANIOBIUS CAPITATUS, new spcciei. 



This species is at once distinguished from cockerelU by the fact 

 that the head, as viewed from in front, is not nearly twice as broad 

 as high, although distinctly broader than high ; the area between the 

 inner eye-margin and the margin of scrobe is nearly as broad at the 

 lower extremity of the eyes as at the upper angle of the scrobe in- 

 stead of much narrowed below; in dorsal aspect the head is more 

 strongly transverse, the frons much loss flattened and more nearly 

 perpendicular; the antennal scape is longer, about six times as long 

 as thick: the general color is much darker. 



Female. — Length 2.75 mm. Head finely and nearly uniformly 

 shagreened and with conspicuous white pubescence, except on the
