and shining with sparse, soft, whitish pubescence dorsad and caudad; 

 the thoracic pleura are finely lined, obliquely so ; the head, thoracic 

 venter and most of the remaining portions of the thorax similarly 

 lined, the vertex transversely so, the scutellum impunctate, longi- 

 tudinally finely lined (the metanotum has not as yet been seen) ; the 

 mesoscutum. however, is somewhat rougher, with fine polygonal 

 figures; surface of the eyes much coarser than the body surfaces. 

 The parapsidal furrows are complete, widely separated at their 

 bases, the caudal margin of the mesoscutum straight, that sclerite 

 shorter than the scutellum which is large and slightly convex ; for a 

 few other general characters see the description of the male follow- 

 ing. The pubescence of the funicle and club in the female antennae 

 is obscure but the funicle joints have at least one whorl of fine hairs 

 distad, more noticeable on joints 4 to 6 but there is also some 

 pubescence farther proximad on the joints; the club bears a few long 

 grooves. 



The male, heretofore unknown, is described herewith. 



Male. — Length, 0.75 mm. ; slightly smaller than the female but otherwise 

 the same excepting in antennal and abdominal characters or the secondary 

 sexual characters usual to the genus. 



Occipital margin of the vertex (dorsal aspect) concave, subacutely emargi- 

 nate at the meson, its two oblique sides meeting there in a point ; ocelli 

 dark like the eyes, smooth, inconspicuous, situated in a mere curved line near 

 the occipital margin, the lateral ocelli somewhat farther from the middle or 

 cephalic ocellus than each is distant from their respective eye margin ; also 

 the distance between the lateral ocelli is at least thrice the distance between 

 each and its respective eye margin ; lateral ocelli slightly farther from the eye 

 margins than they are wide and separated from them by a grooved line, a 

 portion of the " vertexal carina " seen in balsam mounts. 



Abdomen distinctly shorter than the thorax, (lateral aspect) triangular,* 

 the dorsal plane acutely convex, very convex ; (dorsal aspect) triangular, its 

 base truncate, forming the base of the triangle, the second and third seg- 

 ments subequal, at least a third longer than segments 4 to 7 which are short, 

 transverse, straight ; terminal segment slightly longer, very small, conical. 

 Antennae inserted dorsad of the middle of the face, slightly ventrad of a line 

 drawn between the dorsal ends of the eyes (lateral aspect), widely separated, 

 the bulbs being near the eye margins. 



Antennae filiform, much longer than in the female and than the length of 



* In balsam mounts quite differently shaped : ovate, very small, not any 

 larger than the head and with the genitalia exserted. In balsam mounts the 

 abdomen of the male resembles somewhat the female abdomen, lateral aspect, 

 when similarly mounted.
