suggestions of a smootli median discal area. Upper tooth of front 

 tibia moderately strong. Hind tarsus longer than the tibia. Other- 

 wise similar in all respects to L. cavata. 



Female. — Antenna! club robust, much shorter than the funicle. 

 Pygidium highly polished, glabrous, finely and moderately densely 

 pmictate, surface minutely alutaceous; disk strongly gibbose before 

 apex, the apex nearly truncate and somewhat tliickened. Abdomen 

 liighly polished, segments 1-5 subconnate; sixth segment large, 

 apical half with a moderately broad U-shaped emargination. Hind 

 tarsus as long as their tibiae. All claws with a moderately large 

 tooth sUghtly beyond the middle, the surface between the tooth and 

 claw base denticulate. Otherwise as in the male. 



Length. — 11-13 mm. Width. — 5.5-6.7 mm. 



Types. — Holotype and allotype are from Cocliise County, Aiiz., 

 July [Saylor] and are deposited in the United States National Museum 

 (No. 53769). 



Paratypes. — Males, 1; females, 3. Arizona: Cochise County 

 [Saylorl; Pinery Canyon, Cochise County, Chhicahua Mountains, 

 6,000 feet, Jidy 19, 1919 (Witmer Stone) [American Museiun]. 

 Mexico: "Mexico" [Casey]. 



Remarks. — Apparently rather local in our territory. The Mexican 

 examples in the Casey collection agree in all respects except that the 

 female pygidium is more closely punctate on the apical gibbosity than 

 in the typical form. 



PHYLLOPHAGA (USTROCHELUS) TEXENSIS, new species 



Figure 10, m, o 



Male. — Robust-oval, thorax rufous and polished, remamder of 

 dorsal surface rufocastaneous; elytra and sides of thorax usually 

 densely pruinose, apparently glabrous above. Antenna castaneous, 

 club testaceous and subequal to the funicle. Head with dense vario- 

 late punctures, those at the middle of the clypeal disk a little finer 

 than those of the front; clypeal sutiu'e strongly biarcuate; clypeal 

 apex reflexed, subtruncate, the angles broadly rounded; vertex with a 

 moderately strong transverse carina, the siu-face behind this impunc- 

 tate. Thorax with fine, dense, regularly placed punctures, these 

 closer near apex and somewhat sparser at the center of the disk; 

 lateral margins coarsely crenate, with rather short cilia; hind angles 

 obtuse. Elytra with coarse, sparse punctures, with minute hairs 

 visible in a strong light; striae obsolete, except the sutural, which 

 widens noticeably posteriorly. Pygidium evenly convex, with dense, 

 fine punctures and short, minute hair; basal three-fifths pruinose, 

 apical portion polished and less densely punctate. Abdomen flat and 

 pruinose at center, with fine, sparse, setigerous punctures; sixth seg-
