Presternum finely, very densely punctate, and the median part 

 densely clothed with long, erect, inconspicuous hairs; prosternal 

 lobe slightly declivous, broadly rounded in front, and with a broadly 

 arcuate emargination at the middle; prosternal process broad, the 

 sides parallel to behind the coxal cavities, and the apex broadly 

 rounded. Posterior coxae with the posterior margin sinuate and the 

 exterior angle rectangular. Tibiae slender, the anterior and middle 

 pairs slightly arcuate, and with a short tooth on the inner margin 

 at apex. Posterior tarsi about as long as the tibiae, and the first 

 joint as long as the following three joints united. Tarsal claws 

 dissimilar; anterior pair cleft near apex, the teeth nearly equal in 

 length, and acute at the tips; middle and posterior pairs cleft near 

 middle, the outer tooth long and acute, the inner tooth broad at 

 apex, about one-half as long as the outer one, and not turned inward. 



Length, 7.5 mm. ; width. 1.75 mm. 



Female. — Differs from the male in having the front of head more 

 cupreous, and not so densely pubescent ; antennae extending only to 

 middle of pronotum ; presternum sparsely punctate, and not clothed 

 with long, erect hairs at the middle; sides of abdomen slightly ex- 

 posed above ; anterior and middle tibiae unarmed at apex ; posterior 

 tarsi distinctly shorter than tibiae, and the tarsal claws similar on 

 all feet, cleft near middle, the outer tooth long and acute, the inner 

 tooth broad, about one-half as long as the outer one, and not turned 

 inward. 



Length, 8.4 mm. ; width, 2 mm. 



Reclescribed from the male and female cotypes, catalogue No. 224.

Type locality. — Esperanza ranch, Brownsville, Tex. 



Distribution. — Texas : Esperanza ranch, Brownsville, May to 

 July (Charles Schaeffer) ; May 31, 1904 (H. S. Barber)/ Los 

 Borregos, Brownsville, May 21-24, 1904 (H. S. Barber). 



Variations. — This species is rather uniform in coloration and 

 pubescent markings, but sometimes the specimens are covered with 

 a dense white efflorescence, which gives them a different appearance. 

 The antennae are usually serrate from the fifth joint, but occasionally 

 there is a specimen found with the fourth joint feebly serrate, which 

 might cause it to be placed with the species having the antennae 

 serrate from the fourth joint. 



It has only been recorded from two localities in the extreme 

 southern part of Texas, and Frost and Weiss (1921) record it as 

 having been collected on Momma pallida Planch. This is one of 

 the low-growing hackberries. and has been placed in the genus Celtis 

 by some authors. The shrub is known in Mexico and Texas under 

 various local names, such as : " Granjeno," " granjeno huaste o," 

 " capul," and " garabato."
