AMERICAN COLEOPTERA. 129 



from Michigan and New York to Louisiana and Texas, extending to 

 Arizona and the Peninsula of California. The more northern specimens 

 are more shining and smaller with the elytra always paler. In the Texas 

 region the specimens are somewhat less shining with darker color. 



T. latipcilll is Lee. — Head piceous, surface bronzed, front with a slight 

 arcuate impression each side, the anterior supra-orbital puncture unusually deep. 

 Eyes rather prominent. Antennae testaceous. Thorax colored as the head, less 

 than twice as wide as long, apex and base equal, margin slightly reflexed, sides 

 arcuate in front, rather strongly sinuate posteriorly, hind angles acute but not 

 prominent, apical arcuate impression distinct, in front of which the surface is 

 longitudinally wrinkled, median impression moderately deep, on each side of disc 

 a punctiform impression, basal margin longitudinally wrinkled. Elytra broadly 

 oval, very little longer than wide, striate, the striae indistinctly punctured, inter- 

 vals slightly convex, dorsal punctures as in intersectus but each one situated more 

 anteriorly : color yellowish testaceous with an irregular undulating fascia at middle 

 composed of small piceous spots, the apex for a short distance piceous. Body be- 

 neath piceo-testaceous. Legs testaceous. Presternum slightly protuberant at tip 

 and distinctly margined. Claws simple. Length .20 — .22 inch; 5— 5.5 mm. 



Male. — The anterior tarsi have three joints very distinctly dilated and squamu- 

 lose beneath, the middle tarsi narrowly dilated with joints 2 — 4 squamulose 

 beneath, the first joint only at tip. The anal segment is feebly emarginate at 

 middle and the margin on each side has but one setigerous puncture. 



Female. — The tarsi are not dilated. The anal segment entire and with one seta 

 each side as in the male. 



It may be observed in this species that the spurs of the tibiae are 

 less distinctly serrulate than in the two preceding species, the anterior 

 tibial spur especially so. The general appearance of this species is that 

 of a broad fasciatiis. 



There seems very little doubt in my mind that Chaudoir is correct 

 in merely guessing that this species should be referred to Peronoscelis. 

 It should probably be placed near undatus and mexicanus. 

 Occurs in Texas. 



T. pallidum Horn. — Pale rufo-testaceous, subopaque. Head impunctate, 

 without impressions, eyes not prominent. Antennae testaceous. Thorax less than 

 twice as wide as long, sides moderately arcuate in front, oblique and very slightly 

 sinuate behind, hind angles rectangular, not prominent, disc with a finely im- 

 pressed median line and without lateral foveae. Elytra oblong-oval, finely striate, 

 striae not punctured, intervals nearly flat, dorsal punctures not evident. Body 

 beneath smooth, presternum obtuse at tip, not margined. Claws simple. Length 

 .18— .20 inch; 4.5—5 mm. 



Male. — Sexual characters as in latipennis. 



Female. — As in latipennis. 



In this species the mentum tooth is broader and less acute than in 

 those which precede. 



I have seen but two specimens of this species, one 9 from the south- 

 ern district of California, the other from Camp (J rant, Arizona.
