NO. 3568 MELANOTUS — QUATE AND THOMPSON 55 



Holotype of cribriventris : Female, Kosciusko Co., Ind., July 11, 

 1904, W. S. B. (PU). 



Distribution. — New Jersey west to Kansas. 



Illinois: Rock Is.; no date. Indiana: Allen; June. Kansas: Douglas; no 

 date. Maryland: Baltimore, Plummers Is.; April. New Jersey: Warren; 

 June. Ohio: Hamilton, Hocking; June. Pennsylvania: Northampton; June. 

 Tennessee: Morgan; May. 



The long antennae and short third antennal segment are distinctive 

 characteristics of cribriventris, and specimens go through the key with 

 little difficulty. The shaggy antennae are especially characteristic of 

 the male and provide an obvious clue to its identification. 



Blatcliley apparently believed the male and female belonged to two 

 different species. He first named the male longicornis, but this name 

 is preoccupied by longicornis Candeze. Leng observed the homonymy 

 and renamed Blatchley's species blatchleyi. However, cribriventris is 

 merely the female of longicornis Blatchley and is therefore available 

 as a replacement name and has precedence over blatchleyi. Some 

 identifications will bear this latter name, but the correct one is 

 cribriventris.

 twice as long as maximum width; erect male hairs short and 

 inconspicuous.

 punctures on front; sides of pronotum nearly parallel, hind angles a 

 little divergent. 



Genitalia as figm-ed; paramere with well-defined apical blade.
