300 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 45. 



distinctly, and closely punctate, a little more densely toward the 

 sides. Scutellum subtriangular. Elytra distorted by pressure and 

 with the tips broken off, but showing the sculpture very nicely, each 

 with eight entire striae, well impressed and sharp, the bottom of the 

 strife with slightly irregularly spaced elongate punctures, interstices 

 nearly or quite smooth. A distinct and rather long scutellar stria is 

 present in addition to the entire ones described above. Length of 

 fragment, 8.50 mm.; if complete it would probably reach between 

 9 and 10 mm. 



Type.~C&t. No. 59665, U.S.N.M. 



This specimen seems well referable to Platydema, though the size 

 is large compared with most of the recent forms. In life, P. hethunei 

 probably had the facies of P. suhcostatum, but was larger. Several 

 of the recent Mexican species reach a length of 8 mm., and at least 

 one (P. 15-maculatum) measures up to 9 mm. The scutellar stria is 

 distinct in recent forms, and may be well demonstrated by our com- 

 mon P. excavatum. The genus is already known from the Tertiaries, 

 P. geinitzi having been described from the upper Oligocene of Rott, 

 in the Siebengebirge. 



I name this beetle after Dr. Charles J. S. Bethune, of Guelph, 

 Ontario, Canada. 



Genus RHYNCHITES Herbst. 



RHYNCHITES SUBTERRANEUS Scudder. 



An obverse and reverse in good condition, showing dorsal view, are 

 referred to this species with wliich they agree in every essential noted 

 by Scudder. However, the head, between and behind the eyes, and 

 the entire discal surfaces of prothorax and elytra are clothed with 

 long slender curved hairs, not closely placed nor arranged in series. 

 Unfortunately the antermal club of tliis specimen is crossed by a front 

 leg, obscuring the basal joints, so I am unable to determine whether 

 this part is composed of three or of four joints. Length, exclusive of 

 rostrum, 5.25 mm. ; of rostrum, 2.75 mm. ; of elytra, 3 mm. Width of 

 elytron, 1.65 mm. 



The specimens bear the United States National Museum accession 

 number 38133.
