1 8 — Epilragus ovalis is extremely close io plumbcus ami very doublfully 

 different. 



19 — Enrymetopon dubiiim. In the types of this the thorax is a little 

 more coarsely and not quite so closely punctate as in rufipes and 

 the sides of the thorax slightly sinuate near the hind angles. In a 

 large series before me (21 specimens) these characters are evanescent. 



20 — E. emarginaium is also allied to rufipes but is more elongate, some- 

 what convex and with the elytra less densely and somewhat 

 substriately punctate. 



21 — E. carbonatum. The typical series of this species consisted of five 

 specimens. That to which the label was attached is emarginatiun, 

 the other four are males of dubium. Supposing the majority to re- 

 present the species the synonymy is placed accordingly. 



22 — The differences between the forms united as e?)iargtnaium are purely 

 individual. 



23 — The species of Coniontis are with our present knowledge purely 

 opinionative. I preferred to cohsider the forms described as C. 

 elliptica as smaller forms oirobiista in view of the recognized varia- 

 tion in Eschscholtzii ?ix\d vialica. There is almost unlimited op- 

 portunity for new names in this genus. 



24 — There can be no doubt in the mind of any one who will examine 

 a large series oi extricata that cognala Hald. is merely a variety and 

 that arcuata Casey is the female of cognata. 



25 — Plaiydema per nigrum has the form of _7'a72z/j' Fab. but with a more 

 shining surface and more distinct sculpture. The color differences 

 alluded to by Mr. Casey are inexact. 



26 — Rhynchitis naso is allied \.o fossifrons but the thorax is more densely 

 punctured: the striae are also more coarsely punctured. 



Among the Steni the following synonymy has been observed: 



Dianous chalybeus Lee. ^ cserulescens Gyll. A (^ specimen of the latter obtained 

 by me in Scotland has been returned to me by Mr. Casey as chalybeus. 



D. zephyrus Casey = nitidulus Lee. 



Areus Casey = Hemistenus Mots. The genus is not considered a valid one.

 species to offer or desiring a particular line of insects, cannot do better than to avail
