TAXONOMIC STUDY OF MORDELLIDAE — RAY 305 



0.85 mm.'), sides broadest at base, evenly attenuate to apex, apices 

 individually rounded. Intermediate tibiae and tarsi approximately 

 equal in length; penultimate segment of anterior and intermediate 

 tarsi dilated, emarginate at apex, bearing distal segment on its ventral 

 surface. Posterior tibiae with two and a rudimentary third oblique 

 ridge, each extending approximately halfway across outer surface; 

 basitarsi with three, second segment with two oblique ridges, each 

 extending halfwaj' across outer surface. Tarsal claws with four 

 teeth, two distal ones long, acute, two proximal ones short, blunt 

 (fig. 18, k). Outer spur of posterior tibiae almost twice length of 

 inner one. Anal style slightly more than tw^ice length of apical seg- 

 ment (0.95 by 0.45 mm.), rather stout at base, evenly attenuate to 

 apex; last ventral segment almost three times length of penultimate 

 one.

MORDELLISTENA SEPIA, new species 



FiQUKE 19, e 



This species is most closely allied to tahascana Champion (1891, p. 

 330) and may be separated from the latter member of the genus by a 

 distinct difference in color and pubescent maculation, the shorter form 

 and the isosceles condition of the distal segment of the maxillary 

 palpi, the greater length of the fourth antennal segment, and the oddly 

 shaped scutellum. 



Length: 1.5 mm.; including anal style, 2 mm. Form moderately 

 elongate, robust, sides attenuate beyond basal third of elytra, broadest 

 near base of pronotum. Derm warm sepiaceous in color, meso- and 

 metasternum and anal style piceocastaneous. Body densely covered 

 with fine, recumbent, flavobrunneous pubescence, partaking of ground 

 color in the following areas: a somewhat rounded spot on middle of 

 disk of pronotum, a subbasal, subsutural spot extending to middle of 

 elytra, produced posteriorly and recurved anterolaterad, but not reach- 

 ing lateral margins; and a broad, transverse, arcuate band reaching 

 neither suture nor lateral margins and produced anteriorly, almost 

 touching previously mentioned subsutural line. 



Antennae 0.7 mm. long, reaching base of abdomen, filiform, slender, 

 segment 4 twice as long and much broader than 3 ; 5-10 but slightly 

 longer than 4 and subequal in length and width; 11 slightly longer 

 than 10, broadest at apical third, thence rounded to apex. Distal 

 segment of maxillary palpi enlarged, with form of an elongate 

 scalene triangle, apical margin and angles rounded, mesal and lateral 

 margins straight. Pronotum slightly broader than long (0.47 by
