ficult to know how far species differentiation should go in this genus. 

 The author has tried to be conservative in dealing with this genus 

 which shows so many diverging characters. 



EURYMYCTER LATIFASCIA, new species 



Described principally^ from a specimen from Buffalo, N. Y., in the 

 Hubbard and Schwarz collection. 



Length, 7 mm., breadth, 3.2 mm. This species hitherto confused 

 with fasciatus Olivier differs in a number of respects. In fasciatus 

 the thoracic carina is almost straight at the middle, and laterally 

 forms a tubercle at its basal angle and also at its apex. In the new 

 species the carina is slightly arcuate anteriorly at the middle, and 

 laterally curves concavely from a not prominent basal angle to an 

 acute tubercle at its apex. The median line of the beak is less dis- 

 tinct than in tricarinatus. The elytra are smoother and only the 

 third interval is distinctly elevated in latifascia^ while in fasciatus^ 

 etc., the third, fifth and seventh are elevated. The outlines of the 

 fascia in fasciatus are very irregular and angulate, and the fascia 

 is narrower than in latifascia, which has the outlines of this band 

 much more even. 



A second specimen measuring 5 mm. is at hand from Ontario.

EURYMYCTER BICARINATUS, new species 



Described from a single specimen from Tenino, Washington in 

 the Hubbard and Schwarz collection. 



Length, 8.5 mm., breadth, 4 mm. This species hitherto confused 

 with fasciatus Olivier differs in several respects. The rostral carinae 

 are close together and very prominent, with no room for a median 

 carina between them as in fasciatus; the elytral fascia is broader, 

 the strial punctures are irregular in length, many quite elongate; 

 the thoracic carina is even straighter than in fasciatus; the thoracic 

 sculpture is coarser and deeper. 



Type.— Cat. No. 41366, U.S.N.M. 



EURYMYCTER FASCIATUS Olivier 



Macrocephalus fasciatus Oliviee, Entomologie, 1795, vol. 4, No. 80, p. 9, pi. 1, 

 fig. 9. 



The specimen at hand which most nearly answers the description 

 of this' species, originally described from Georgia, is from Crescent 

 City, Fla., in the Hubbard and Schwarz collection, labeled Jan- 

 uary 12. This has an almost straight basal thoracic carina; two
