1 907.] SPECIES OF CHYPTOCEPHALIXE BEETLES. 845 



eyes which meet at the middle ; clypeus finely rugose ; antennae 

 with the lower five joints black above, obscure fulvous below, 

 third shorter than fourth, both very elongate, rest wanting. 

 Thorax nearly twice as bi'oad as long, sides rounded, moderately 

 narrowed antei-iorly ; surface exti-emely finely and subremotely 

 punctured, only visible under a strong lens, the base with a deep 

 transverse depression near the posterior angles. Scutellum very 

 broad at base, impunctate, black. Elytra with a shallow trans- 

 verse depression below the base across the suture, finely and 

 rather regularly punctate-striate, the space near the suture at the 

 basal portion irregulaily punctate, black, with a slight purplivsh 

 gloss ; the humeral red patch extending nearly, but not quite, to 

 suture and dowuAvards to about one-third the length of the elytra, 

 the apical spot i-ound or nearly so, impunctate. Body below 

 clothed with fine yellow pubescence, apex of the tibias and the 

 tarsi more or less fulvous. Prosternum inuch longer than broad, 

 strongly punctured. 



Hah. Bolivia. 



Smaller than any other species of similar coloration and dis- 

 tinguished by the very fine thoracic puncturation. Female 

 unknown. 



Griburius ornatus, sp. n. 



Yellowish white ; thorax with two longitudinal fulvous bands, 

 sparingly punctiu^ed ; elytra strongly punctate-striate, da,rk ful- 

 vous, each with five elongate, whitish, raised spots (2.2.1) and 

 similar nari-ow stripes near lateral margins. 



Length 3| millim. 



Head strongly but sparingly punctured, a small piceous spot at 

 A'^ertex and at base of antennte, punctures likewise piceous, ground- 

 colour pale yellow ; emargination of eyes triangular ; antennae 

 very slender, lower five joints pale, rest black, third joint much 

 shorter than fourth. Thorax scarcely twice as broad as long, sides 

 nearly straight, but slightly narrowed anteriorly, median lobe of 

 basal margin broadly rounded ; surface sparingly (but strongly and 

 irregularly) punctured at sides, middle impunctate, basal margin 

 accompanied by a row of deep punctures ; a broad longitudinal band, 

 irregularly widened into spots at sides, is placed at each side near 

 middle, the latter has likewise a small spot situated at base. 

 Scutellum pale yellow. Elytra subcylindrical, parallel, the fulvous 

 portion separated by i-aised whitish elongate spots, of which one is 

 placed near suture, one at shoulders, two at middle, transversely, 

 and a round one at apex ; the last interstice near margin is neai-ly 

 entirely whitish, except below middle ; all the pale spots are with- 

 out punctures, the latter are arranged as follows : — two irregular 

 short rows near suture, followed by four closely placed rows, a 

 few punctures below shoulders and two rows near margins com- 

 plete the sculpturing ; none of the rows extend to apex, the first 

 of the longer ones divides the pale discoidal spot near suture. 

 Legs pale fulvous, anterior femora incrassate.
