Middle and Southern States, not rare. The anterior tibie are regular in all 
my specimens. 
In Dejean’s Catalogue this species is placed under Lycoperdina, but the pro- 
sternum between the anterior coxe although narrow is very distinct. 
Enpomycuvus Weber.

Middle, Southern and Western States, rare. 
Mycetina Muls. 
Antenne articulo 3io longiore, articulis ultimis maioribus, distantibus obliquis, 
ultimo truncato; palpi maxillares tenues, fere acuminati; prosternum inter 
coxas anticas latiusculum, mesosternum postice truncatum. 
a. Corpus glabrum; thorax basi marginatus; prosternum spatulatum. 
1. M. perpulchra, oblonga, nigra nitida, thorace rufo, medio nigro, im- 
pressionibus basalibus brevibus linea basali coniunctis, elytris subtiliter punc- 
tulatis maculis utrinque duabus lete rufis, tarsis piceis. Long. 16. 
Endomychus perpulcher Newman, Ent. Mag. 5, 390. 
Lycoperdina 4-guttata Mels. Proc. Ac. Nat. Sc., 3, 176. 
Middle, Southern and Western States. Varies with the thorax immaculate; 
the mesosternum is sharply margined between the coxe; the anterior tibie of 
the male are flattened, and slightly angulated internally. 
b. Corpus parce subtiliter pubescens ; prosternum spatulatum. 
2. M. testacea, elongata, sordide ferruginea, parce fulvo-pubescens, tho- 
race linea laterali distincta, impressionibus basalibus brevibus, linea basali 
coniunctis, elytris parce punctatis, antennis piceis, basi pallidioribus. Long. :15. 
Lycoperdina testacea Ziegler, Proc. Ac. Nat. Sc. 2, 272. 
Lycoperdina pilosa Mels. Proc. Ac. Nat. Se. 3, 176. 
Middle and Southern States. The anterior tibie appear alike in all my spe- 
cimens. 
Lycoperdina lutea (Mels. loc. cit.) as far as I can judge from the badly pre- 
served specimen which served as the type, is merely an immature specimen 
of this species. ‘This insect is Epipoeus ferrugineus De}. Cat., but not Lyco- 
perdina ferruginea Lec. Ann. Lye. 1, 172. 
c. Corpus hispidum; prosternum dilatatum, non spatulatum. 
3. M. hispida, ovalis, obscure ferruginea, pilis erectis dense hispida, tho- 
race linea laterali a margine remota, impressionibus basalibus brevibus, linea 
basali transversa nulla, elytris punctatis nigris, margine usque ad apicem late 
ferrugineo, antennis nigro-piceis, basi ferrugineis. Long. -15—:18. 
Erotylus hispidus Herbst. Kafer, 8, 374, tab. 137, fig. 13. 
Lycoperdina vestita Say, Journ. Ac. Nat. Sc. 5, 304. 
Middle and Southern States. Varies with the elytra entirely ferruginous. The 
prosternum is here much wider than in the preceding species, is not prolonged 
over the mesosternum, but articulated closely with it; the mesosternum is 
therefore flat, not concave, as in the two above described. This difference 
seems to have been considered as generic by Chevrolat, and the species occurs 
in Dejean’s Catalogue as Ephebus limbatus.
