176 H. 0. FALL. 



Hab. — Lower California, El Taste and Santa Rosa. 



I know of only two examples of this beautiful species, the type 

 from the former, and a second specimen collected by Mr. Beyer at 

 the latter locality and kindly sent me for examination. 



7. T. sordid a Horn. — "Cylindrical, oblong, more than twice as long as 

 wide; black, head and thorax with dirty yellow pubescence, elytra with a band 

 of same along the base, a very narrow sinuous band at middle and an irregular 

 apical space of same color. Antennae black. Head black, punctuation concealed. 

 Thorax broader than long, sides arcuate in front, slightly sinuate in front of the 

 hind angles, the latter distinct, disk gibbous behind the middle, a slight sulcus 

 from the apical margin to the summit of the gibbosity, surface distinctly granu- 

 late and not densely clothed with dirty yellowish pubescence and with inter- 

 mixed, short, black, erect hairs, but without brush at the summit of the gibbosity. 

 Elytra hut little wider than the thorax, the surface with irregular strife of coarse 

 deep, not closely placed punctures, and clothed with velvety black pile arranged 

 in quite small spots; a dirty yellow band composed of spots across the base, a 

 sinuous indistinct band at middle and a space near the apex of similar pubes- 

 cence. Body beneath black, subopaqe, surface granular, dashed with recumbent 

 dirty yellow pubescence. Length 7.5 mm." 



"One specimen, Texas; special locality unknown." 

 The above is Horn's description. Specimens referred to this spe 

 cies by Mr. Schaeffer, and it seems to me correctly so, have been 

 taken by him at Brownsville, Texas, and one of these is now before 

 me. In it, it should be remarked that the thorax and elytra are of 

 equal width, the latter almost without granulations. The brush- 

 like tufts of blackish hairs are more numerous than in any other of 

 our species, and are arranged in three longitudinal lines on each 

 elytron. 



8. T. pulchella Schaef. — Oblong, slightly more robust thau gibbosa, black 

 with very short pale brown recumbent pubescence, intermixed with longer erect 

 hairs; sides of thorax, base of elytra, a narrow strongly dentate median band 

 aud apex with denser white pubescence. Antennae brown, club slightly longer 

 than the preceding joints united ( £> ), joints 5-8 a little transverse. Head 

 and thorax strongly granulate, the latter transverse, subequal in width to the 

 elytra, widest near the middle, the sides arcuate in front and rather abruptly 

 shortly sinuate behind, hind angles almost rounded ; median channel from the 

 front margin to the summit of the gibbosity well marked, the summit clothed 

 with short erect ferruginous hair. Elytra with irregularly closely placed coarse 

 deep punctures but not granulate. Between the angulate median fascia and the 

 apical white space is a white longitudinal streak terminated posteriorly by a 

 small tuft of black hairs. At an equal distance from the suture at basal fourth 

 is a similar tuft, these representing in this species the usual anterior and posterior 

 transverse series. Body beneath black, shining, densely pubescent, abdominal 

 segments remotely punctate and sparsely grHnu late at sides and apex. Length 

 5.5-7 mm.
