400 MEMOIRS ON THE COLEOPTERA 



elongate elytra, smaller head and smaller, more parallel and more 

 quadrate prothorax, on which the minute wavy sculpture is so 

 strong that it imparts an aeneo-opalescent lustre, wholly foreign to 

 Icevigatus; rufipennis Makl., is probably synonymous with longi- 

 pennis. 



Paraquedius n. gen. 



Another singularly isolated species, the Quedius puncticeps of 

 Horn, has to serve as the type of a very distinct group of the old 

 genus Quedius, with either a generic or subgeneric status, in 

 greater probability the latter than the former, though in either 

 case it is in large degree a matter of opinion. The body is moder- 

 ately narrow, subparallel, very highly polished throughout, black 

 in color, sometimes with feeble aeneous lustre. The head is short 

 and rhomboidal, because of the great prominence of the eyes, and 

 the two impressions on the front, widely and transversely separated 

 between the eyes, are conspicuous; the antennae are rather long, 

 fully as long as the head and prothorax, with the penultimate joint 

 somewhat longer than wide even on the compressed side; the pro- 

 thorax is rather longer than wide, oval and not evidently wider than 

 the head, the parallel elytra distinctly wider, though somewhat 

 longer than wide, the evenly distributed and not very close-set 

 punctures notably fine; there is a feeble impression at the inner 

 apical angle of each elytron in my single specimen. The abdominal 

 punctures are very minute and sparse, rather closer basally, the 

 first three segments more than usually impressed transversely at 

 base. The length is about 7.5 mm., and it is an inhabitant of 

 Vancouver Island. No other species has been discovered thus far. 



Anaquedius n. gen. 



This group is, like Hemiquedius and Paraquedius, monotypic at 

 present, but, in spite of this, I can see no other very rational course 

 than to regard the Quedius vernix of LeConte, as of truly generic 

 value; it is certainly inharmonious with the other species, not only 

 in its striking habitus but in many important structural characters, 

 such as the long and very slender, filiform antennae and the com- 

 pletely unimpressed abdominal segments, with peculiarly coarse 

 and remotely scattered punctures and absence of sexual modifica-
