P. spumarius var. leucopthalmus (Linnaeus). 



Entirely dark brown or black. 

 P. spumarius var. lateralis (Linnaeus). 



Black; a broad, light stripe on costa. 

 P. spumarius var. leucocephalus (Linnaeus). 



Dark brown or black; vertex and anterior half of pronotum 

 yellow. 

 P. spumarius var. marginellus (Fabricius). 



Black ; vertex and anterior half of pronotum, and a stripe on 

 costal margins of elytra, yellowish white. 

 P. spumarius var. lineatus (Fabricius). 



Yellowish-white ; a median stripe arising sometimes on point of 

 vertex, sometimes on pronotum. and extending to apex of clavus, 

 and a stripe on corium parallel with this, black. 

 P. spumarius var. pallidus (Zetterstedt). 



Pale yellowish white. 



Distrbution : Specimens have been examined from the New 

 England States, New York, and from Ontario and Quebec (Can.). 

 It has been reported from Nova Scotia (Ball), from North Caro- 

 lina (Metcalf) ; and in Europe it has a wide distribution with an 

 even larger number of recognized varieties. Specimens have been 

 examined of the varieties fasciatus, lineatus, and pallidus from 

 "Waterloo, Belgium, 8-'io," of the variety pallidus from "Edin- 

 burgh, Scotland, 8-i9-'i2," and of the variety ustulatus from 

 "Dalmatia, Saloni, 8-23-'io."

Ent. News, xxix, 3, 1918. 



Readily distinguished from spumarius by its elongate form, and 

 from lineatus by its larger size and distinctive coloring, as men- 

 tioned in the key to species. Length 8-10 mm. ; width 2.5-3 mrn - 



Vertex, length slightly greater than two-thirds width, medially 

 weakly carinate, laterally depressed ; ocelli equidistant from each 

 other and from posterior margin of tylus ; pronotum medially 

 weakly carinate, anterior margin broadly rounded, lateral margins 

 equalling distance between ocelli ; elytra nearly parallel-margined. 



Genitalia : Female, last ventral segment one-half length of pre- 

 ceding, convex ; pygof ers broad, length equalling combined basal 

 width, outer margin incurved throughout basal third and indented 

 at middle, exceeded by stout ovipositor one-half their length. 

 Male, last ventral segment twice length of preceding, convex ; 

 plates long, broad at base, laterally extended here to one-half
