The common Lipeurus of the turkey (Meleagris gallopavo). I have 
specimens collected from the wild turkey by Prof. H. W. Parker. 
Lipeurus jejunus Nitzsch. 
On Anser albifrons gambeli (Cook collection). 
Lipeurus leucopyegus, var. fasciatus. 
On Botaurus sp. (Burnett collection). 
Lipeurus pustulatus. 
On “ Halietus leucocephalus” (Burnett collection). 
Lipeurus botauri, n. sp. 
Slender, slightly marked with brownish, clypeus rugose. Head tapering; clypeus 
circular in front, with surface distinctly roughened with papilose rugosities, two 
hairs at the clypeal margin and two or three others on the margin of head in front of 
antenne and two on temporal lobe; occiput slightly concave; prothorax slightly 
wider behind, tinged with brown at sides; metathorax quadrate, wider behind; 
posterior margin concave; legs large, anterior femora incrassate; abdomen with 
faint brownish markings on each segment, most conspicuous on segments 4, 5, and6; 
angles of segments 3, 4, 5, 6, and 7 with short hairs. 
On bittern or stake driver, Botaurus leutiginosus. 
Lipeurus pullatus Nitzsch. 
(1842) (?) Lipeurus staphylinoides Denny, Monog., p.180, Pl. XV, fig. 2. 
(1866) Lipeurus pullatus Nitzsch, Zeitschr. f. ges. Naturwissensch., Vol. XXVIII, p. 387. 
(1872) Lipeurus pullatus Giebel, Epiz., p. 236. 
(1880) Lipéurus pullatus Piaget, Les Pédic., p. 339, pl. XXVII, fig. 9. 
On Sula bassana and Sula alba, Burnett collection (Nos. 91 and 92). 
Specimens labeled from Sula alba lighter colored than those from Sula 
bassana, but the latter agree perfectly with Piaget’s excellent figure. 
It would seem that Denny’s staphylinoides must come here, but the 
Specimens do not agree with his description or figure. 
Lipeurus infuscatus n. sp. (PI. II, figs. e. and f.) 
Light fuscous, a transverse clear space just behind the clypeus. 
Female.—Head quite uniformly fuscous and elongate cordate, the anterior portion 
rounded, with a transverse clear space about one-third distance between the tip and 
antenne extending to margins; antennz rather long, second joint rather slightly 
longer than the others, all slightly fuscous; temporal lobes oval, narrowing poste- 
riorly; occiputslightly concave; prothorax enlarging slightly behind, slightly darker 
at the margins, the usual bands not very distinctly marked ; metathorax a little longer 
than prothorax, widening behind; legs unicolorous, the anterior ones with more dis- 
tinctly marked apical ring to the femur and external marginal stripe on tibie; 
abdomen enlarging posteriorly, marginal bands rather broad, median bands extend- 
ing to the clear spiracular spaces separated from each other by distinct sutural 
bands, a single row of hairs near the posterior margin and one or two hairs at the
