punctures not verj^ large but deep, rather sparse, becoming gradually very fine 

 an* sparse toward apex, surface alutaceous, reticulate, the fine lines radiating 

 from each puncture, the sculpture effaced near the suture. Legs moderate in 

 length, slender. Length 2.4 mm. ; width 0.85 mm. 



Wisconsin (northeastern). 



Tlie largest species of the genus, being nearly twice as large as 

 the next in size, but possessing all the generic features of Vano- 

 nus. It will be readily identifiable b}^ its size, sculpture and ves- 

 titure. 



2. V. piceiis Lee.— Proc. Acad. Nat. Sci., Phila., 1855, p. 276 (Xylophi-

Moderately stout, black, with the legs and antennse more or less 

 dark red-brown ; body sometimes paler, with the head always 

 dark ; integuments shining ; pubescence very minute, close and 

 evenly decumbent. Head transverse, finely, strongly and rather 

 densel}' punctate, the eyes separated by fnllj'^ twice their own 

 width ; antennae two-fifths as long as the bod}', graduall}'^ and 

 quite perceptibly incrassate, the tenth joint slightly transverse. 

 Prothorax distinctly narrower than the head, only slightly wider 

 than long, parallel, narrowed anteriorly, the apex arcuate and 

 distinctly narrower than the base ; disk convex, very finely, 

 densely punctate, the subbasal impression bisinuate along its 

 posterior margin. Elj'tra scarcel}^ three-fifths longer than 

 wide, twice as wide as the prothorax, parallel and feebly arcuate 

 at the sides except near the base, broadly rounded behind, feebly 

 impressed near the base and within the humeri, the omoplates 

 moderatel}'^ large and prominent ; punctures somewhat fine, mod- 

 erately close-set tow^ard base, minute and more distant behind. 

 Abdomen minutely punctate and pubescent. Length 1.65 mm.;

Similar to the preceding but much smaller, black, the antennae 

 paler; integuments polished; pubescence minute, decumbent,
