EEVISION OF ELEODIINI BLAISDELL. 497 



larva) 10 mm. in leii<2:th (Plate 13, figs. 4-14), supplemented by 

 eight others. The illustrations give the characters better than a 

 labored description. 



LARVA OF ELEODES DENTIPES. 



Length, 10 nnn. ; color, castaneo-testaceoiis, at times fuscous. Sur- 

 face glabrous. Form elongately cylindrical, flattened ventrally. 



The ultimate and jiosterior border of the penultimate segments, 

 both above and beneath, sparsely clothed with long flying hairs ; the 

 under surface of the thoracic segments are similarly clothed, the 

 hairs being a little longer and rather denser; the sides of the head 

 beneath are rather more conspicuously pubescent. Similar but 

 shorter hairs are scattered here and there over the dorsal surface of 

 the tergites, apparently without a definite orderly arrangement, ex- 

 cept laterally just a little in advance of the posterior border on each 

 segment there is a longer hair, and these are observed on all the seg- 

 ments, forming a series on each side; on the prothorax there is a 

 hair at each angle. There is also an evident series on the sternites 

 just within the lateral border on each side; four or five hairs were 

 counted; the number varied, possibly from being broken off; the 

 series are definite and continuous on the abdominal sterna. 



Head (Plate 13, fig. 0) somewhat circular in outline, but truncate 

 at base, transverse without the clypeus and lal)rum, slightly de- 

 pressed; just behind each antenna are two ophthalmic spots; all are 

 small and transverse, the anterior a little more external than the 

 posterior, separated b}' about five times their own length; iimne- 

 diately in front of the anterior are three or four setigerous punctures. 



Anfciiiia' three-jointed, situated iunnediatel}' behind the mandibles 

 in articular cavities with rather prominent borders; joints one and 

 two about equal in length and about twice as long as wide, terminal 

 joint very small and bearing a seta at tip; retractile. (See figs. 10 

 and 9, Plate 13.) 



Mandibles short, somewhat irregularly triangular in outline, apex 

 emarginate, superior cusp longer than the inferior; superior surface 

 feebly convex, slightly irregular; external surface arcuate as viewed 

 from above, more strongly so just apicad to the middle when viewed 

 from below; external margin of superior surface with a cluster of 

 some three or four seta^ at middle, a couple of sette more basacl ; in- 

 ternal margin with a small triangular and acute dentiform process 

 slightly basad to the mid-point between apex and molar. 



Inferior surface irregularly convex, excavated within the cuspi- 

 date apex, distinctly evident as viewed from below. Internal surface 

 with a prominent molar (figs. 13 and 14, Plate 13). Membranous 

 lobes so evident in the adult, obsolete.
