BATRISINI 243 



dorsal view 0.469 x 0.55 mm. (in reality the abdomen is 0.737 mm. long but this 

 length is not visible from above; the tergites are I (0.335), II (0.067), III 

 (0.067), IV (0.201) and V (0.067 mm.) long, or in a ratio of 5/1/1/3/1. Total 

 length 1.7 mm. Greatest width 0.67 mm. 



Rich chestnut brown with palpi, antennae, and legs paler; the integument 

 polished and shining; sparsely but distinctly punctulate, each puncture raised 

 and bearing a long seta. 



Head transverse with long, rounded tempora so that the head has a semi- 

 circular occipito-genal contour; eyes prominent, medianly placed, each com- 

 posed of about 72 very minute facets. Head abruptly narrowed apical of eyes, 

 the sides slightly convergent, with obliquely truncate antennal tubercles, thus 

 the head has a transversely oblong vertexo-frontal contour. Front concave be- 

 tween antennae, declivous, apically subtuberculate. Vertex medianly vaulted 

 and surmounted by a prominent median, longitudinal carina extending from 

 occiput to a line drawn through bases of antennal tubercles. Vertex lightly 

 punctulate posteriorly, coarsely punctate on antennal tubercles, glabrous at an- 

 terior center. A deep, circular, nude vertexal fovea each side on a line through 

 middle of eyes and mesiad of antennal tubercle, mutually connected by a U- 

 shaped sulcus with obsolete inner and strong outer wall, the sulcus communi- 

 cating broadly with the frontal depression. Therefore the vertex has an in- 

 verted Y sulcus with the long vertexal carina entering between the fovea! 

 arms. Each side of head with a prominent oblique carina from tempora, above 

 eye, to lateral margin of antennal tubercle; from a lateral view there is a 

 second angulated carina which arises at middle of anterior margin of eye and 

 extends apically to form the bead of the clypeal margin. Genae furnished with 

 a beard of bristling setae. Labrum remarkably transverse, short, deeply, and 

 entirely concave along margin, with each lateral angle produced sharply as a 

 sharp cusp. Ventral surface of head anteriorly densely set with small, crowded 

 punctures. 



Maxillary palpi four-segmented; first segment minute; second elongate- 

 conical, apically three times wider than base ; third short, in the shape of an 

 elongate triangle, longer than wide, apically twice as wide as base, wider than 

 second; fourth longest and widest, obliquely narrowed at base, lengthily nar- 

 rowed to apex, subsinuate ventrally. 



Antennae eleven-segmented, distant, elongate, subgeniculate because of 

 the strong four-segmented club; segment I oblong; II subcylindrical, much 

 narrowed; III-VII elongate-obconical; last four segments as long as second 

 to seventh inclusive, distinctly wider and the eighth, ninth, and tenth ab- 

 normal: VIII with the ventral face produced apicolaterally, IX and X with 

 ventral faces strongly produced to form a triangular crest, this crest foveate 

 on mesial face of IX and foveate on lateral face of X. 



Pronotum typical of genus, truncate-cordate. A pair of strong, conico- 

 pyramidal, sharp-pointed antebasal spines; disk simple; no sulci; a large tri- 

 angular foveaform depression lateral to each antebasal spine, a smaller fovea- 

 form depression far down on pronotal flank and lateral to the lateral fovea,
