OMOTYPHUS. 473 



yellow pubescence, interrupted at and below the middle by an oblique row of longitudinal dark fulvous or 

 fuscous spots, forming two oblique rows, which are wider apart at the sutural than at the lateral portion.

I must separate the present insect on account of the elytral pattern, which is the same 

 in the three specimens before me ; the colour of the pubescence is rich dark yellow, and 

 the two rows of spots, deviating from each other at the suture, are distinctly visible 

 with the naked eye ; the long antennae will also assist in distinguishing 0. semifasciatus. 



7. Omotyphus bituberculatus. 



Obscure fulvous or fuscous, thickly clothed with variously coloured pubescence ; antennae fulvous, the seventh 

 and eighth joints fuscous ; thorax with obsolete longitudinal stripes ; elytra with a basal depression, thickly 

 clothed with brown and yellow pubescence, each with a subsutural longitudinal tubercle below the middle. 



Length 1^ line. 



Head short and broad, thickly clothed with yellow and fulvous pubescence ; palpi filiform ; antenna? half the 

 length of the body in the male, shorter in the female, the third, fourth, and fifth joints, slender and 

 elongate, of nearly equal size, fulvous, the three apical joints also fulvous, the seventh and eighth joints 

 fuscous or piceous ; thorax subquadrate or one half broader than long, distinctly transversely depressed 

 across the disc, covered entirely with either fulvous or yellowish pubescence forming alternate obsolete 

 stripes ; elytra rather strongly punctate-striate, the interstices slightly raised, the basal portion also raised 

 and limited behind by a transverse depression, near the suture below the middle is a narrow elongate 

 tubercle placed on the second interstice.

This seems to be a most variable little species in regard to coloration, scarcely two 

 specimens being alike ; in some the elytra are nearly black, the pubescence forming 

 white and dark fulvous or ferruginous spots, while in others the entire apices are ferru- 

 ginous ; a few have the elytra clothed with golden-yellow pubescence, varied by spots 

 of a ferruginous colour ; in all, however, the postmedian short sutural elevation is 

 present, a character that will principally assist in the recognition of 0. bituberculatus. 



8. Omotyphus scutellatus. 



Below fulvous ; above clothed with greenish pubescence : the sixth to the ninth joints of the antennse black ; 

 scutellum fulvous ; elytra finely punctate-striate, one or two spots near the suture and an oblique row of 

 spots below the middle, obscure fulvous. 



Length 2 lines. 



Head thickly clothed with yellowish-green pubescence ; the lower part of the face smooth, fulvous ; antenna? 

 scarcely half the length of the body, the terminal joints incrassate, the five lower joints fulvous, the three 

 or four following joints black, the apical ones fulvous ; thorax twice as broad as long, the sides straight, 

 the surface scarcely visibly depressed at the sides, covered entirely with greenish pubescence which hides 

 any punctuation ; scutellum fulvous, clothed with long hairs ; elytra with the base scarcely raised or 

 depressed below, thickly clothed with the same coloured pubescence as the head and thorax, the punc- 

 tuation fine, a small dark fulvous spot is placed at the middle near the suture, and three or four similar 

 transversely oblique spots (longitudinal in shape) below the middle ; legs fulvous ; posterior tibia? with a 

 double spur.

The greenish colour of the pubescence and the fulvous scutellum distinguish
