BRACHYGLUTINI 183 



Drasinus cisinsularis new species 



Holotype Male. Measurements: Head 0.189 x 0.308 through the eyes; 

 antennae 0.569 mm.; pronotum 0.276 x 0.335 mm.; elytra 0.469 v 0.57 mm.; 

 abdomen from a dorsal view 0.268 x 0.53 mm.; first tergite 0.201 x 0.53 mm.; 

 total length 1.2 mm.; greatest width 0.57 mm. 



Body yellowish-brown, moderately shining, clothed with long, flavous, 

 subdecumbent pubescence, very indistinctly punctulate. Head with prominent, 

 large eyes (0.1 x .053 mm.) of about 32 very coarse facets. Occipital portion 

 of the vertex simply and transversely gibbous, not medianly carinate. Occipito- 

 cervical field transversely sulcate with a sharp but minute longitudinal median 

 carina which does not extend to vertex. Center of vertex very slightly de- 

 pressed. Two vertexal foveae in a line with the second transverse row of ocular 

 facets; each fovea nude, sharply defined and of the diameter of an ocular facet, 

 neither connected with each other nor with the front by sulci. Sides of head 

 sharply incised by a short, slightly oblique, subpubescent cut just anterior to 

 each eye and hence near the lateral base of each antennal prominence. At the 

 mesial base of each antennal prominence is a small, nude, foveaform pit. These 

 pits, then, form a second, more anterior pair of vertexal foveae and presumably 

 are consequences of the antennal articulation. Front between antennal bases 

 simple and declivous to the clypeus. Clypeus simple, not rugose. Labrum simple, 

 its apical margin slightly concave. Ventral surface of the head subtriangular, 

 with the lateral margins carinated and with a strong median, longitudinal 

 carina, the latter enclosing at its anterior tenth a small subcircular fovea. 



Maxillary palpi four-segmented. First segment minute and cylindrical; 

 second long, arcuate, swollen distally ; third rounded-triangular with the outer 

 face evenly convex and inner face angulate-convex, short, only about a third 

 as long as second, and as wide as distal portion of second; fourth slightly 

 longer than second, wider than other segments, obliquely truncate at base, 

 outer face convex, inner face nearly straight, apex rounded and obtuse, bear- 

 ing a small palpal cone. 



Antennae ten-segmented; segment I subcylindrical; II subcylindrical with 

 rounded, tapered ends, narrower and shorter than first; III-VII subcylindrical 

 to submoniliform, gradually shorter and gradually slightly narrower; VIII-X 

 forming the club, eighth and ninth of the same subtrapezoidal form with trun- 

 cate base, oblique divergent sides and subtriangular apex, the eighth larger 

 than seventh and smaller than ninth; distal (tenth) segment about as long 

 as preceding two united and wider than ninth, base truncate, sides convex, 

 apex gradually rounded. 



Pronotum wider than head, similar in shape to hirsutus, with three circular 

 subbasal, free, nude foveae, a lateral on each side and a median. Basal margin 

 with a row of coarse punctures. 



Elytra with two deep, circular, nude, subbasal foveae on each elytron, the 

 sutural fovea at the origin of the well-marked, entire sutural stria and the 

 discal fovea at the origin of the well-marked discal stria which reaches slightly
