TAXONOMIC STUDY OF MORDELLIDAE RAY 275 



TOMOXIA BREVIPENNIS, new species 



Figures 17, a; 19, c 



This species is most closely allied to hinotata, new species, but may 

 be easily separated from that member of the genus by the greater 

 number of elytral spots, the longer, narrower body, the shorter, 

 broader, anterior and intermediate tibiae, the shorter distal segment 

 of the maxillary palpi, and the narrower scutellum. From latenotata 

 Pic (1924, p. 23) it may be separated by the much shorter anal style, 

 the narrower scutellum, the shorter anterior and intermediate tarsi, 

 and the different position of the elytral spots. 



Length : 6.6 mm. ; including anal style, 8.5 mm. Form moderately 

 robust, elongate, sides narrowing posteriori}^, broadest near middle of 

 pronotum. Derm piceous, eyes, antennae, mouth parts, anterior 

 femora and tarsi, and spurs of posterior tibiae castaneous, remainder 

 of legs and ventral abdominal segments fuscocastaneous. Body 

 densely covered with fine, recumbent pubescence, reddish brown ex- 

 cept for the following whitish areas : mixed on head ; covering mar- 

 gins of pronotum broadly, with a curved band extending from an- 

 terior angles into disk and meeting posterior marginal line on either 

 side of middle; scutelkim entirely; an indeterminate humeral spot 

 shortly curving into disk, an oblong scutellar spot extending along 

 suture, a large, rounded, postmedian, subsutural spot, and a pair of 

 irregular postmedian spots on middle of disk curving posteriorly, 

 reaching neither suture nor margins ; intermediate and posterior legs, 

 parts of mesosternum and metasternum, and bases of abdominal seg- 

 ments, basal one and anal style broadly, whitish. 



Antennae 2.1 mm. long, reaching posterior angles of pronotum; 

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

 long as 4 but successively narrower distad ; 11 distinctly longer than 

 10, broadest beyond middle, sides and apex rounded. Distal segment 

 of maxillary palpi enlarged, with form of a broad scalene triangle, 

 sides curved, apex straight. Pronotum much broader than long (2.8 

 by 2.1 mm.), sides rounded, broadest medially, base arcuate, midbasal 

 lobe short, but rounded. Scutellum of a broad, modified triangular 

 shape, twice as broad as long, sides angularly cutting into elytra, 

 apex broadly rounded, subtruncate. Elytra three-fourths longer than 

 broad (4.5 by 2.6 mm.), sides attenuate posteriorly, apices individu- 

 ally rounded. Anterior tarsi much shorter than their tibiae; inter- 

 mediate pair equal in length ; three intermediate segments of anterior 

 and intermediate tarsi dilated, flattened. Tarsal claws bearing three 

 teeth, distal one longest (fig. 17, a). Outer spur of posterior tibiae 

 one-half longer than apical ventral segment (1.9 by 1.2 mm.), stout.
