G. A. K. MARSHALL OX COLEOFTERA [Jail. 19, 



Abdomen with the second segment shorter than the third and 

 fourth togethei- and sepai'ated fi-om the fii'st by a faint cui-ved 

 incision, the remaining incisions deep and straight, the intercoxal 

 piece bi'oad and ti-uncate ; metasteiiium veiy short. 



Legs moderately long ; femoiu clavate, the posterioi- pair not 

 neai'ly reaching the apex of tlie elyti-a ; the antei-ioi- and intei'- 

 mediate tibite with their internal apical angles strongly incurved, 

 the antei'ioi" paii- with theii' inner edges always, the posterior 

 paii's fi-equently, denticulate ; tarsi usually broad and spongy 

 beneath, the fiist joint nearly always longei' than the second 

 or thii'd, veiy lurely longei- than these two together, the second 

 and thii'd joints generally equal ; the three basal joints usually 

 of about the same width, but the thii'd strongly lobate and 

 sometimes bi'oader than the others ; claws moderate, simple, and' 

 free; antei'ioi' coxie contiguous, intermediate pair nearly so. 



To prevent misunderstanding, it may be explained that in de- 

 sci'ibing the sculptui-ing of the elyti'a the space between the 

 sutui'e and the fii'st sti'ia is called the fii'st interval. This system 

 was adopted by Gyllenhal in his earliei' desci'iptions (e. g. jJcistil- 

 larius), but in his later woi'k he calls this interval the sutui'e, 

 and the next interval the fii'st ; in this he is followed by Fahra?.us.
