The buccal process is moderately produced iu Eleodes hlancJiardil 

 and strongly so in EJeodhnorpha holcan. (See Plate 8, fig. 24.) 



Eyes narrowly subreniforni, transverse, and slightly oblique, su- 

 perior margins rounded, the inferior slightly subtruncate against the 

 gena^ ventro-anteriorly, rounded somewhat behind this point and 

 continuously so with the arcuate posterior margin; the anterior 

 margin is broadly and evenly emarginate, adapted to the deflexed 

 frontal ridge, and briefly so to the superior genial angle. Stu'face 

 fineh' faceted and not setigerous. 



Gular region^ besides being punctato-granulate, is finely and ir- 

 regularly or transversely regulose. The gular sutures are widely 

 separated inferiorly at the sides of the occipital foramen, and some- 

 what arcuately converging anteriorly to become nearly contiguous at 

 a point, wdiose distance behind the base of the mentum is equal to the 

 width of the gular peduncle, and continuing forward for a short 

 distance to become divergent, passing to the mental angles of the 

 peduncle, botuiding laterally the small triangular submentum, whose 

 base is usuall}^ a little longer than one of its sides. 



The transverse cephalic groove is strongly imjDressed across the 

 apex of the submentum, becoming less so outwardly just behind the 

 posterior boundary of the buccal fissures. 



Gular peduncle short and slightly deflexed, formed bv the sub- 

 mentum, whose base forms a free margin, to which is attached the 

 mentum. 



Gula. — Between the gular sutures posteriorly is the subtriangular 

 gula, whose base forms the straiglit infei'ior boundary of the occipi- 

 tal foramen. 



Lahrum more or less transverse, simuite at middle, sinus rounded, 

 lobes rounded and continuously so wdth the sides; surface feebly 

 convex, punctate, setie longer latero-anteriorly, and decurved ; the 

 antei'ior niargiu (>ach side of tlie central sinuation, just beneath 

 clothed with dense transverse tufts of golden pubescence {l<d)i(/l 

 tufts), wliicli are directed downward, inward, and slightly forward. 



Me7itu)n variabk', internally giving attachment to the labium; 

 apex of middle h)be free. (See descriptions of species.) 



Antenna' variable in length. The outer three or four joints are 

 always more or less feebly compressed and slightly dilated ; second 

 joint alwa^'^s short, frecjuently wider than long, and subannular: tlie 

 third always long, from three to five times as long as the second and 

 usually about as long as the fourth and fifth taken together; the 

 fourth and fifth may be equal in length, or the former a little the 

 longer; fifth, sixth, and seventh usually about ecjual in length and size 

 and obconical in form; eighth more or less triangular; eighth, ninth 

 and tenth usually inoie or less transverse; eleventh oval and ob- 

 liquely truncate at tip. The first joint is moderately arcuate, and
