AMERICAN COLEOPTERA. 291 



small wliite globular fungus growing on dead pines, each fungus 

 having a pair of the species. 



E. Hornii Crotch. — Broadly oval, fulvous, feebly shining, surface sparsely 

 clothed with short fulvous pubescence. Head sparsely punctulate. Antennre 

 fulvous, joints of funicle proportioned as in monogama. Thorax nearly twice 

 as wide as long, sides moderately arcuate and gradually narrowed from apex 

 to base, and with a feeble sinuation in front of the basal angles which are 

 email and acute, apex feebly emarginate, angles obtuse, margin flattened, more 

 widely explanate posteriorly and very slightly reflexed, surface moderately 

 <lensely punctulate. Elytra conjointly as wide as long, broadest near the 

 middle, apices rotundato-truncate, margin explanate and reflexed, surface 

 moderately densely punctulate. Prothorax beneath nearly smooth, at sides 

 transversely wrinkled. Abdomen rather more coarsely punctured than the 

 upper surface. Intercoxal process broad. Epipleurse very sparsely punctulate. 

 Length .16 — .18 inch; 4 — 4.5 mm. 



The sexual characters in this species are the same as- in monogama . 

 and Mr. Crotch's remarks are erroneous. 



The form of this species is nearly that of hehola but even broader, 

 its color and size making it one of the most conspicuous species in 

 our fauna. 



Occurs near Grimsby, Canada, whence specimens were sent me 

 some years ago by Mr. Johnson Pettit. 



E. helvola Erichs. — Broadly oval, piceous brown, feebly shining, sparsely 

 clothed with short brownish pubescence. Head coarsely and densely punc- 

 tured. Antennae as in monogama, brownish, club darker. Thorax rather more 

 than twice as wide as long, apex deeply emarginate, base subtruncate, sides 

 strongly arcuate slightly narrowing at base, sinuate in front of the hind angltes 

 which are subacute and slightly prominent, margin broadly explanate and 

 slightly reflexed, surface moderately densely punctate and subgranulate. 

 Elytra oval, a little longer than wide, narrower at apex, moderately convex, 

 suture slightly elevated, margin reflexed but gradually evanescent to tlu- tiji 

 which is truncate, surface moderately densely punctulate with a subgranular 

 aspect. Body beneath moderately densely punctate. Femora rather coarsely 

 and densely punctate. Intercoxal process" broad, truncate. Length .12 inch ; 

 3 mm. 



The sexual characters are as in monogama, but the sinuation 

 of the middle tibiae and the prolongation inwards at tip still more 

 pronounced. 



The color of this species varies somewhat, usually entirely piceou.-^ 

 brown, often with the entire margin and suture more or less rufou.'^. 

 The hind angles of the thorax vary a little in the degree of their 

 prominence, as well as the sinuation in front of them. 



Mr. E. Eeitter (Verhandl. des Naturf. Vereines in Briinn, xii • 

 has apparently separated two color varieties of this species, to one of
