210 Arthur M. Lea: 



The teeth on the fourth segment of the iibdonien of the male 

 ^re intermediate between those of insif/n/ renfris and dentiventris, 

 •differing from the former in being sliorter, not quite as close to 

 the margins, on the same plane as the base of the segment, and 

 the median tooth quite distinctly a tooth, and not a slight thicken- 

 ing of a membranous flap, although remnants of such a flap are 

 present. From the latter species it differs in the outer teeth being 

 •decidedly longer than the middle one, more distant from each other, 

 and conspicuously projecting as teeth over the fifth segment. To 

 see them most clearly they should be examined from the direction 

 of the head, as, in this species and in rhntiveiitrls, they are some- 

 what obscured by clothing. 



The base of the prothorax is transversely impressed, with the 

 imj^ression foveate, but the depressed parts are somewhat obscured 

 by clothing. 



A female, possibly belonging to this species, differs in being some- 

 ■\vhat wider, elytra more densely clothed, head with rather dense 

 clothing across base, and femora and tibiae almost flavous. 



Scydmaenus fiiiihriatus, n.sp. 



Of a rather dingy castaneous, suture somewhat darker than rest 

 ■of elytra; tarsi and palpi flavous. Elytra with rather short and 

 depressed stramineous hairs, prothorax rather densely clothed at 

 sides, and sparsely elsewhere; not at all on middle of disc; head 

 sparsely clothed, except at sides and in middle of base, where 

 the clothing is dense. 



Head feebly transverse; moderately bilobed Ijetween antennae. 

 Eyes small and moderately prominent. Antennae moderately 

 long; club conspicuously four-jointed. Prothorax lightly transverse; 

 base foveate. Elytra not very wide, base distinctly wider than pro- 

 thorax, sides regularly rounded and widest across middle. Legs 

 rather long; hind coxae moderately separated; femora suliclavato.

The general shape and appearance is much like liiat of Hete/rofi- 

 nathus robusfus, but the club is distinctly four-jointed. At a 

 glance it appears close to the preceding species. l)ut tlie l>ases of tlie 

 prothorax and elytra are different; the elytra and their rlothim: 

 are not as in hrevijrilis. 



The cephalic fascicles are not separated the entire width of the 

 base, but appear extended round and almost drawn .together, caus-
