DESCRIPTION OF A NEW GENUS AND SPECIES OF HETEROMEEOUS 

 COLEOPTERA OF THE FAMILY CISTELID^ FEOM HONOLULU. 



BY CHAS. O. WATERHOUSE. 



The species here described has been in the British Museum col- 

 lection for some years, but without a name. Upon examination it has 

 proved to be new to science, and to have characters which separate i't 

 from any genus known to me. I propose to call the genus Lahetis. 



LABETIS, n. gen. 



Eyes reniform, widely separated above. Anterior coxse slightly separated. An- 

 terior tibise flattened, gradually but slightly becoming wider from the base to near 

 the apex, at the apex suddenly enlarged on the outer side ; the tibise of the inter- 

 mediate and posterior legs slightly enlarged at the apex. The 3rd and 4th joints of 

 the anterior and intermediate tarsi furnished with a lamella, the 3rd joint of the 

 posterior tarsi has a well developed lamella. The other characters as in Allecula, as 

 given by Lacordaire (Gen. Col., v, p. 502). 



This genus closely resembles Allecula, but the anterior tibiae are 

 unlike those of any of the family, resembling slightly those of Micro- 

 zoum in the Opatrides, but more elongate, and without any mesial tooth. 



Labetis tibialis, sp. n. 



EJortgato-ellipticus, convexus, flavus, nitidus, subtus pieens ; thorace dense 

 punctata ; elytris fortiter punctato-striatis, interstiiiis sat convexis crebre pnnctatis. 



Long. 5^ lin. 



Sordid yellow, moderately shining, less so on the head and thorax ; body 

 beneath shining, pitchy. Head densely and rather strongly punctured. Thorax 

 one-third broader than long, gently convex, gently narrowed from the base to the 

 front, densely and strongly puijctured, the anterior angles obtuse and not prominent, 

 sides gently arcuate anteriorly, the posterior angles nearly right-angles, but blunt.
