Xantholinus or Gijrohypnus. The same author replaces 

 sanguinipennis , of LeConte, by lecontei, because of sanguini- 

 ptiinis Kolen., of the Island of Crete, but, as the latter is a 

 Eulissns and sanguinipennis, of LeConte, is a Gyrohypnus, 

 the change of name is unnecessary. 



Xestolimis n. gen. 



In the formation of the sides of the head behind the eyes, 

 fine arcuate gular sutures subuniting behind the middle of the 

 post-oral surface and extremely minute, remotely scattered 

 punctuation of the head, this genus approaches the third 

 group of Gyrohypnus, as defined above, but it differs from 

 any member of Gyrohypnus in its short, stout and rather com- 

 pressed maxillary palpi, with the last joint obviously shorter 

 than the preceding and very obtusely conical ; also in its well 

 developed, stout and compact antennae, with the second and 

 third joints equal and elongate-obconic in form. The abdo- 

 men is very greatly developed, being nearly as wide as the 

 elytra and conspicuously wider than the head and prothorax, 

 giving the species a peculiar appearance, and the elytra are 

 differently sculptured from those of the preceding genera. 

 At present we have only discovered two species as defined 

 below : — 



Stout in form, moderately convex, polished throughout, the under surface of 

 the head without trace of minute strigilation ; prothorax, elytra and legs 

 pale rufo-testaceous throughout, the second more fiavate than the first; 

 antennae rather more dusky, the head darker piceo -testaceous, clouded 

 with blackish above, the abdomen piceous-black, not paler at tip; head 

 oblong, distinctly elongate behind the antennae, the sides for some 

 distance behind the eyes parallel and straight, then very broadly round- 

 ing into the base, the frontal grooves moderately long and deep, the 

 oblique ocular fine and short; punctures minute and very widely dis- 

 persed, a narrow indefinite post-ocular longitudinal line, punctured more 

 closely in two series, with a larger puncture behind the middle, the 

 under surface finely, very sparsely punctate ; prothorax fully two-fifths 

 longer than wide, obviously narrower than the head, the sides distinct- 

 ly converging from the well rounded apical angles, the apex arcuate; 

 dorsal punctures very fine, 7-8 in number, the sublateral series mu«h 

 shorter, more close -set, arcuate, composed of about seven equally 

 minute punctures ; there are some also sparsely scattered toward the 

 sides anteriorly; elytra rather elongate, fully as long as the prothorax
