rower lateral margins, and in the prosternal process being 
only slightly arched longitudinally between the coxae ; where- 
as in brunnescens the prosternal process is strongly arched 
between the coxae and reflexed posteriorly.

Soronia (pars) Horn, 1879, Trans. Amer. Ent. Soc., 7 : 287. 
Front lobed over the insertion of the antennae; labrum 
feebly bilobed; mandibles bifid at tip; labial palpi filiform; 
eye facets about as in Soronia , finer than in Lobiopa; an- 
tennal grooves parallel; mentum emarginate; elytra dis- 
tinctly costate; epipleurae extend to suture; tarsi feebly 
dilated. 
Amphotis contains two North American and three Euro- 
pean species.

Amphotis ulkei Leconte, 1866, Proc. Ac. N. S. Philad., p. 376. 
Soronia ulkei Horn, 1879, Trans. Amer. Ent. Soc., 7 : 307. 
This species extends from Massachusetts to the District 
of Columbia in the nests of Crematogaster lineolata, Formica 
schaufussi , and Formica integra. It is strictly myrmeco- 
philous in the early spring but in the fall of the year is 
found in decaying fungi.

Dr. Hugo Kahl of the Carnegie Museum has kindly loaned 
me the types (collected by Schwarz June 17 at Ft. Monroe, 
Virginia), all of which are testaceous. Two specimens in 
the U.S.N.M. from Mobile, Alabama, December 6 are dark 
testaceous, and a specimen from Southern Pines, N. C., 
March 3 in the collection of C. A. Frost is rufo-piceous. This 
species differs from ulkei in the additional two costae on each 
elytron and in the narrower and less emarginate mentum.
