1938] 
North American Nitidulidae 
157 
pleurae extending to apex of elytra but not to the suture; 
anterior tarsi feebly, middle more feebly, and posterior very 
feebly dilated. 
Phenolia is Nearctic in distribution and contains only one 
variable species. 
Phenolia grossa (Fabricius) 
Nitidula grossa Fabricius, 1801, Syst. Eleuth., 1 : 347. 
This species is found beneath bark and in fungi from 
Canada and Maine to Wyoming and Texas. 
Soronia Erichson 
Soronia Erichson, 1843, in Germar, Zeitschr. Ent., 4: 277. 
The front lobed over the insertion of the antennse; eye 
facets about as in Amphotis , finer than in Lobiopa; man- 
dibles bifid at tip, the inner cusp slightly proximal to the 
outer and smaller; antennal grooves strongly convergent 
posteriorly; labrum feebly bilobed or emarginate, labial 
palpi filiform, mentum rectangular with small process in 
center of anterior margin ; elytra very feebly costate ; epi- 
pleurae may extent to the suture ; tarsi very feebly dilated ; 
outline more oblong and less oval than in Lobiopa. 
Although Soronia is widely distributed in the Old World, 
only three species are known from the New World, one each 
from North America, Brazil, and Mexico to Brazil. Blatch- 
ley and Hamilton each described a species from eastern 
United States. Both species, however, belong in Lobiopa. 
Soronia guttulata (Leconte) 
Lobiopa guttulata Leconte, 1863, Smiths. Misc. Coll., 6 : 64. 
Leconte described this species from a specimen collected 
by Ulke in Illinois. In the Leconte collection there is no 
specimen from Illinois, but there is one from Canada labelled 
“type” and one each from Marquette, Michigan and Arizona. 
It has been taken in New York, and specimens from Iowa, 
Oregon, and California (McCloud, Carrville, and Facht) 
have been seen. The dates of capture are from April to 
June 26.
