NOTES ON STAPHYLINID BEETLES—BLACKWELDER 83 
nitidissimus Bernhauer by Bernhauer, but I am unable to distinguish 
them from Panama examples of planellus. 
Examples in the Baker collection identified by Dr. Cameron as 
Paralispinus exiguus Erichson are quite distinct from that species 
(and genus) as it occurs at the type locality (Puerto Rico). 
Genus LISPINUS Erichson 
Lispinus Ertcuson, Genera et species Staphylinorum, p. 828, 1840. 
Diagnosis.—Having the characters listed above for the subfamily 
Osoriinae, the tribe Lispinini, and the subtribe Lispini; gular sutures 
usually present, sometimes merely as pits; hypomeron with a raised 
line, which forms a right or obtuse angle near the front coxa; cavity 
of the mesosternum feeble with sides not elevated; abdominal sternites 
with diagonal strigae, which are sometimes not completely separate 
from the coarse punctures. 
Remarks.—The removal to Pseudolispinodes of the species not hav- 
ing diagonal strigae on the sternites, to Holosus of those having an 
acute hypomeral angle, to Relinda of those having a modified meso- 
sternum, and to Paralispinus of those with contiguous anterior coxae 
leaves in Lispinus a homogeneous series of species, of which each 
agrees closely with the genotype in structural characters, This 
series can be separated into two groups by the structure of the pro- 
notum. The 18 species that I have examined and am placing in this 
genus have previously been placed there with the exception of b- 
striatus Fauvel, longipennis Cameron, and sinuatus Bernhauer, which 
were described and cataloged in Lispinodes and Holosus. This will 
probably still be a fairly large genus when all the foreign elements 
have been removed from it. 
Subgenus LISPINUS sensu stricto 
Diagnosis—Having the characters listed above for the genus 
Lispinus; pronotum scarcely narrower at base than base of elytra; 
side of pronotum with a longitudinal fovea from base. 
Remarks.—The typical subgenus will undoubtedly contain most 
of the species assigned to this genus. I have seen 16 species, which 
differ only slightly in appearance and not appreciably in structure. 
SPINILUS, new subgenus 
Genotype.—Lispinus (Spinilus) bisiriatus (Fauvel) (see p. 81). 
Diagnosis.—Having the characters listed above for the genus 
Lispinus; pronotum much narrower at base than base of elytra; side 
of pronotum with an abrupt fovea near basal third instead of the 
usual longitudinal depression.
