face; the females have this tarsomere normally formed and not brushy be- 

 neath. In addition most of the species have the males with special modifications 

 of the head. 



The following species is new. It is the first species of the genus known 

 outside of Brazil, and may form the type of a new genus although I have not 

 followed this latter course as both of the specimens at hand are females. 



Xybaris funiculis new species 



Cotype Females. Measurements: Head 0.20 x 0.268 mm.; antennae 0.40 

 mm.; pronotum 0.23 x 0.288 mm.; elytra 0.41 x 0.536 mm.; abdomen from 

 dorsal view only 0.134 mm., in reality the first visible tergite, but the true 

 total abdominal length 0.422 mm.; total length from strict dorsal view 0.974 

 mm.; greatest width 0.536 mm. (PI. VII) 



Body subglobose, yellowish-brown, moderately shining, unifonnly punc- 

 tulate. Pubescence long (setae 0.033 mm.) on elytra and abdomen, stout and 

 yellowish in color; setae slightly shorter on head and pronotum. Pubescence 

 on the whole conspicuous when compared to Scalenarthrus, Berdura, Xybarida 

 with very indistinct pubescence. Head in dorsal outline subtrapezoidal, with 

 the eyes 0.087 mm. long, 0.03 mm. in diameter, and composed of about twenty- 

 four very coarse facets. Tempora 0.033 mm. long. Vertex evenly subconvex, 

 with two large and deep vertexal foveae on a line through the anterior third 

 of the eyes. Each vertexal fovea has the diameter of an eye facet, with nude, 

 cylindrical walls, and separated from the adjacent eye by the foveal diameter. 

 These foveae free, not connected to each other or to the front by a sulcus. A 

 conspicuous transverse cleft arising just posterior to the anterior prominence 

 of each antero-lateral corner of the vertex, and extending medianly to a point 

 opposite each vertexal fovea. Front simple, steeply declivous to the simple, 

 nude epistome. Labrum simple. Mandible simple, left crossed dorsal to right; 

 no external basal tooth. Bases of maxillae relatively wide, and mentum 

 relatively long and narrow. Ventral surface of the head with a high median, 

 longitudinal carina; a biarcuate lateral carina each side; an ocular carina 

 which arises at the anterior margin of the eye, and remains in contact with 

 the eye, to join the lateral carina beneath the middle of each eye. (PI. VII, 11) 



Maxillary palpi normal, four-segmented; first segment minute; second 

 elongate, arcuate, slender at base and inflated apically; third short, subtri- 

 angular; fourth longest and widest, obliquely truncate at base, subacute at 

 apex, conico-ovate, bearing an apical palpal cone. 



Antennae normal, eleven-segmented, widely separated at base; segments 

 I and II subconical, relatively large; III obconical, smaller than second; IV 

 to VIII closely articulated, subequal, shorter than third; IX transverse, wider 

 than eighth, about as long as eighth; X wider and longer than ninth, sub- 

 trapezoidal; XI relatively large, subasperate, twice as wide as tenth and 

 as long as fourth to tenth inclusive, subovate with a bluntly rounded apex. 



Pronotum obcordate with a subbasal lateral fovea on each side and a
