the third and fourth interval and on each of the third, fourth and seventh 

 intervals a little before middle and on the third, fourth and fifth about apical 

 third reddish yellow. Head beneath with four or five large punctures on each 

 side. Body beneath smooth and shining. Anterior femora with a tooth, front 

 tibias arcuate and with a rather strong tooth below middle ; intermediate and 

 posterior femora and tibiae mutic. 



Female. — Differs from the male in having the beak longer and narrower 

 before the antennal insertion, and not dilated at apex and the tooth on 

 anterior femora much smaller, anterior tibiae feebly curved, otherwise as the 

 male. Length 8-10.25 mm. 



Texas, one male (O. Dietz) ; Los Borregos near Brownsville, 

 Texas, one female in the National Museum (H. S. Barber). 



This species looks very much like a small Eupsalis minuta in form 

 and coloration, but has a different form of head and antennae and 

 longer beak. It is very close to the Mexican H. distans from which 

 it seems to differ only in the markings of elytra. 



The male in my collection, collected by the late Ottomar Dietz, was 

 only labelled " Texas " but as he also collected in Brownsville and 

 received afterwards some material from there I think that the speci- 

 men came from Brownsville, as I greatly doubt the occurrence of this 

 species outside of semitropical Texas. 



Since Dr. Horn's revision of the Brenthidse^ two species represent- 

 ing two genera new to- our fauna have been added and to facilitate the 

 recognition of these and the one described above a table for the 

 identification of genera and species known to occur in North America 

 is given below. 



In Genera Insectorum and Coleopterorum Catalogus the genus 

 Cylas is not included in the family Brenthidae. The genus is a dis- 

 turbing element and is perhaps better placed in a separate family. 



Table of Genera and Species of North American Brenthid^. 



1. Head longer than broad, oval, prolonged and convergent behind the eyes, 



beak of female shorter than that of the male 6 



Head short, transverse or quadrate, hardly prolonged and not convergent 

 behind the eyes, beak of female either equal in length to that of the male 

 or longer 2 



2. Antennal joints two to eleven equal in width, or the outer slightly narrower; 



head simple without any projecting hind angles, not strongly con- 

 stricted behind, vertex not, or at most faintly sulcate ; beak very dis-
