angles where they are slightly arcuate, near the basal angles sinuate ; apical 

 angles feebly rounded, basal angles acute, rectangular ; apical margin straight, 

 basal margin arcuate at middle ; surface rather coarsely punctate and on each 

 side at middle near base shortly impressed. Elytra as wide as the prothorax 

 at base ; sides feebly arcuately narrowing to apex ; apices rounded ; surface 

 punctate-striate ; intervals visibly punctate, the punctures slightly smaller than 

 those of the striae. Surface below shining and feebly pubescent, punctuation 

 of abdomen coarse and rather dense at sides, finer and more sparsely placed 

 at middle. Abdominal lines feebly carinate and rather short. Length 4 mm. 



Brownsville, Texas (Point Isabel, August 5). 



There is also a specimen before me, collected by the late Ottamar 

 Dietz in Brownsville, which is slightly larger, the thorax has at 

 ■middle of apical margin, a carina-Iike elevation and the apical margin 

 is not straight but oblique from the angles to the middle. The disk 

 is rather flat and the sides are more suddenly deflexed than in the 

 above described species, which causes this point to appear obtusely 

 carinate. The presternum differs also in being transversely deeply 

 impressed and the front tibiae are more dilated at apex with the inner 

 margin arcuate. I take this specimen to be the male of the species 

 •described above, as Reitter described similar modification of the 

 thorax of the male of his H. mexicanus; the male of H. groiivellei, 

 Gorh., has no elevated carina at the middle of the anterior margin, 

 but has this margin projecting hood-like over the base of the head. 



Of the described Mexican species H. parallchis, Gorh. seems to be 

 very near H. texanns, but in the latter the punctures of the elytral 

 intervals are very distinctly visible, which in parallelus are said to 

 be so fine as not to be easily seen. The figure of the female of H. 

 grouvellei Gorh. from St. Vincent, Grenada, closely resembles the 

 above described texanus, btit that species has the elytral intervals not 

 punctate and the male has the thorax differently formed. 



Seventeen or eighteen species of this aberrant genus are known 

 which look more like Cryptophagids than Languriids. The genus 

 was first placed with the Rhisophagincu, transferred later to the 

 Cryptophagidcr, but on account of the tarsal structure placed by Grou- 

 velle and Gorham with the Langiiriince.
