﻿MELOLONTHIDiE OF THE UNITED STATES. 271 



One specimen found with the preceding. This species is by its sculpture related to 

 D. punctata, but the thorax is more coarsely punctured, and the costse of the 

 elytra are marked with a very strong row of punctures, which with the punctures 

 between the geminate rows are furnished with short but stout suberect hairs : the 

 punctures of the thorax and those near the frontal suture also emit hairs. The la- 

 brum is more deeply emarginate than in the other species, but the under part of the 

 claws is as long as the upper, the thorax has a narrow apical membrane, and all the 

 other characters are of this genus. 



22. D. subangulata, oblonga, convexa, nigro-picea nitida, capite dense punctata, marginato, fere 

 hemihexagono, antice late truncato, thorace haud dense punctato, lateribus rotundatis medio subangu- 

 latis angulis posticis valde obtusis, elytris fortiter seriatim punctatis, punctis internis solis confusis, 

 costis parum distinctis subtiliter uniseriatim punctatis, tibiis anticis acute tridentatis. Long. -34. 



One specimen, Oregon, Col. McCall. The under part of the claw is a little shorter 

 than the upper, and less obviously truncate than usual. 



23. D. bidentata, ovata, convexa, nigro-picea, vix Eenescens nitida, capite parcius fortiter punctato, 

 clypeo rotundato, marginato, sutura frontali impressa, tborace parce fortiter punctato, lateribus oblique 

 late rotundatis, angulis posticis obtusis, elytris fortius punctatis, tricostatis, tibiis anticis bidentatis.

Georgia, two specimens. Differs from all others known to me by the ovate body, 

 the sparsely punctured head, and bidentate tibiae. The punctures between the suture 

 and the first dorsal costse are confused, those between the other two costae and the 

 first are less so, but still somewhat confused. The punctures of the under surface 

 are larger and more abundant than usual : the propygidium is more prominent than 

 in the other species and is marked near the apex with a tolerably strong transverse 

 raised line. 



The following species cannot be refered to its proper division, from the loss of the 

 head. 



24. D. tenuis, elongata, cylindrica testacea, thorace confertim punctato, antice posticeque angustato, 

 lateribus rotundatis medio fere angulatis, elytris seriatim punctatis, punctisque paucis internis con- 

 fusis, tricostatis, tibiis anticis obtuse subdentatis. Long. «28. 



A dead specimen found at Vallecitas, San Diego County, California. Resembles 

 in its proportions D. angularis, and probably belongs to Div. IV., but differs greatly 

 in the sculpture of the elytra ; the punctures of the first interstice are confused, those 

 of the other intervals between the costse, are represented by rows of punctures equal 

 in size to those of the regular rows but more distant ; the costae are without punc- 

 tures. The terminal tooth of the anterior tibiae as usual is long, the others are 

 almost obsolete : the lower part of the ungues is acute, and hardly shorter than the 

 upper; the posterior tibiae have more long hairs than in D. angularis.
