Mordellistena.'] HETEBOMERA. 71 



bro\ra, the others black ; anterior tarsi yellow-testaceous, the others 

 partly reddish ; antennae with the fourth joint about oue and a half 

 times as long as third ; maxillary palpi with the last joint securiform. 



Female black, with the thorax and abdomen red or yellowish-red ; 

 mouth, base of antennae, anterior legs, and part of tarsi redilish- 

 testaceous ; antenna? with the fourth joint scarcely longer than third ; 

 maxillary palpi with the last joint oblong, slightly securiform.

BK. humeralis, L. Black, or fuscous, clothed with silky yellowish 

 pubescence, with the base of the antennae, front and sides of thorax, a 

 large patch at each shou"lder, and the legs testaceous or rufo-testaceous ; 

 base of femora and part of posterior tibiae and tarsi fuscous ; the 

 pubescence, as Thomson observes, has a slight violaceous reflection ; 

 punctuation very fine ; antennae moderately long ; head transverse, 

 straight at base ; thorax transverse, strongly bisinuate at base, 

 posterior angles obtuse but almost right angles ; scutellum obtusely 

 triangular; elytra not as broad at base as thorax, gradually narrowed 

 behind, separately rounded obtusely at apex ; anal process long, slender 

 and pointed ; posterior tibiae with three fuscous strigosities before apex ; 

 claws slightly denticulate. L. 3-4 mm. 



Male with the last joint of the maxillary palpi almost triangularly 

 securiform, and the lateral border of thorax and spot at shoulders well 

 determined. 



Female with the last joint of the maxillary palpi oblong-securiform, 

 and the yellow colour on thorax and elytra not well defined, thorax 

 sometimes entirely yellow (M. lateralis, pars).

V. lateral is, 01. (M. lateralis, auct. ; variegata, F.). This variety, 

 which has by so many authors been regarded as a separate species, can 

 hardly be considered distinct ; the fuscous strigosities at the apex of the 

 posterior tibiag are a little shorter and less oblique, and the proportional 

 length of the third and fourth joints of the antennae is said to be different, 

 but the latter character is very uncertain ; the only real difference lies 

 in the colour, and this is so variable in both M. TiumeraUs (especially in 

 the female) and M. lateralis that it can hardly be regarded as a distinc- 

 tive character ; the yellow spot at the shoulders of the elytra is extended 

 towards apex, and leaves only the suture and the sides dark, and the 

 dark colour of the thorax extends further along base ; the antennae and 

 legs are entirely or almost entirely testaceous ; sometimes the elytra 

 appear to be almost entirely yellow with the exception of the apex.
