TOMOXIA FIEBRIGI, new species 



Figure 17, d 



This species is closely allied to auratonotata Eay (1936a, p. 145) 

 but may easily be separated from the latter member of the genus by 

 the broader scutellum, shorter intermediate tibiae, and the equality 

 in length between abdominal segments 3 and 4. 



Length: 3.95 mm.; including anal style, 4.65 mm. Form short, 

 quite robust, subcuneate, broadest at middle of thorax, sides narrow- 

 ing posteriorly. Derm entirely black, except for labial palpi, which 

 are orange-red. Body densely , covered with fine, recumbent, silvery 

 pubescence, rufobrunneous on elytra. 



Antennae 1.25 mm. long, reaching middle of lateral pronotal mar- 

 gin; segments 3 and 4 equal; 5-10 each as long as 4, considerably 

 broadened apically; 11 distinctly longer than 10, oval, sides rounded, 

 apex slightly rounded. Distal segment of maxillary palpi enlarged, 

 form of a scalene triangle, basal angle a right angle, outer margin 

 broadly rounded, inner margin almost straight, corners rounded, base 

 arcuate, midbasal lobe short, sides angular, base truncate. Scutellum 

 twice as broad as long, sides slightly angidar, posterior emargination 

 wanting. Elytra four-tenths longer than broad (2.65 by 1.85 mm.), 

 sides attenuate for their entire length, apices broadly, individually 

 rounded. Intermediate tarsi distinctly longer than their tibiae; 

 penultimate segments of anterior and intermediate tarsi simple'. 

 Tarsal claws with four distinct, broad, blunt teeth, distal one longest, 

 and a small subacute, premedian tooth (fig. IT, d). "Median claws" 

 twice as thick at base as medially, apical half of mesal margin with 

 four thin, very acute teeth, outer edge rounded. Outer spine of 

 posterior tibiae twice as long as inner one. Anal style twice as long 

 as apical ventral segment (0.7 by 0.35 mm.), very stout, short, evenly 

 attenuate, broadly truncate at apex.
