NORTH AMERICAN COLEOPTERA. 145 



mens collected by Dr. Palmer in Coabuila have been sent to the editors 

 of the Biologia Centrali- Americana the species will doubtless receive at- 

 tention from Mr. Waterhouse. 



Southwestern Texas and Coahuila, Mexico. 



Regarding Halecia Mr. Waterhouse remarks (Biol. Cent. Am. vol. iii, 

 pt. 1, p. 5) : " This genus, as at present constituted, is found throughout 

 America from Pennsylvania to Patagonia." I am -not aware of any 

 species from the Atlantic region which can be referred to Halecia. 



CHRYSOBOTHRlJii Esch. 



C ignicollis n. sp. — Dark bronze, head and thorax bright coppery red. 

 Clypeus broadly but not deeply emarginate. Front densely coarsely punctured, 

 nearly flat %, more convex J, the latter with distinct smoother spaces; occiput 

 with smooth median line. Thorax twice as wide as long, sides strongly arcuate in 

 front, feebly at middle, obliquely convergent behind, surface coarsely but not 

 closely punctured at middle, very densely and coarsely at the sides, base deeply 

 bisinuate. Elytra little wider than the thorax, sides nearly parallel, apical third 

 obliquely narrowed, apices separately rounded, lateral margin posteriorly serru- 

 late, subsutural costa extending from apex to middle, a deep depression at middle 

 of base, the surface rather densely and coarsely punctured with an elevated in- 

 distinct space at basal third, a larger quadrate space slightly behind the middle, 

 another one-fourth before the apex. Body beneath coarsely not closely punctured, 

 last ventral segment serrulate at the sides. Length .28-. 30 inch ; 7-7.5 mm. 



Male. — Anterior femora toothed, the tooth serrate outwardly; anterior tibiae 

 slightly arcuate and with an acute tooth one- third from apex : middle tibise slightly 

 arcuate and sinuous on the inner side; posterior tibise straight. Last ventral 

 rather deeply semi-circularly emarginate. 



Female. — Anterior femora as in "J, , anterior tibise slender slightly arcuate, 

 without tooth ; middle and posterior tibise straight, not sinuous on the inner side. 

 Last ventral very feebly emarginate. 



A small species resembling aintlgnd. in sculpture. It belongs to a 

 small group in which the male anterior tibiae are toothed near the tip, 

 all of which differ in the form of the clypeal emargination. 



This species is moreover noteworthy in having the middle S tibige 

 sinuate within. 



Occurs in Colorado and lexas. 



iSiCHIZOPlTS Lee. 



S. Sallei n. sp. — Oblong oval, moderately robust. Head coarsely and very 

 densely punctured. Thorax transverse more than twice as wide as long, broadest 

 at base, sides gradually sinuately narrowing to the front, coarsely, deeply and 

 densely punctured, a very deep oblique impression on each side. Elytra a little 

 wider than the thorax, sides nearly parallel in front, apical half gradually con- 

 verging, apices separately rounded, surface coarsely punctate scabrous, color
