NOTES ON STAPHYLINID BEETLES—BLACKWELDER 85 
which depart most widely from the more general slender form of 
this tribe. I have seen only two species that belong here, H. tachini- 
formis and H. navicularis Cameron. 
NEOLOSUS, new subgenus 
Genotype.—Holosus (Neolosus) tachyporiformis Motschulsky. 
Diagnosis.—Having the characters listed above for the genus 
Holosus; general form similar to subgenus Relinda; pronotum dis- 
tinctly narrowed behind, transversely impressed before base; hypom- 
eral line distinct but enclosing a longitudinal area, and with the 
angle near the coxa right or obtuse (and somewhat rounded). 
Remarks.—Holosus tachyporiformis Motschulsky and H. insularis 
Fauvel differ so much from H. tachiniformis Motschulsky in the shape 
of the pronotum that I separate them under this name. Their form 
is rather similar to that of the other new subgenus Relinda. from which 
they differ in the hypomeral angles being not acute. 
RELINDA, new subgenus 
Genotype.—Holosus (Relinda) mycetoporiformis Motschulsky. 
Diagnosis.—Having the characters listed above for the genus 
Holosus; hypomeron with a raised line forming a right or obtuse 
angle near the front coxa; mesosternum with a cavity with abruptly 
elevated sides for the reception of the tip of the prosternum. 
Remarks.—This subgenus is proposed for the inclusion of two species 
of Holosus (olisthaeriformis and mycetoporiformis) that differ struc- 
turally from the types of Holosus sensu stricto and Neolosus, although 
having an appearance much like the species of Neoiosus. 
Genus PARALISPINUS Bernhauer 
Ancaeus FauveEt, Bull. Soc. Linn. Normandie, vol. 9, p. 60, 1865 (not Risso, 1816). 
Paralispinus BERNHAUER, Deutsche Ent. Zeitschr., 1921, p. 67 (as a new name). 
Remarks.—This genus is included here because it has almost invari- 
ably been confused with Lispinus or Pseudolispinodes. It was 
founded by Fauvel for a single species from Mexico (megacephalus), 
of which I have three examples from Guatemala and one fragmentary 
specimen from Costa Rica. Sharp, in the Biologia Centrali-Ameri- 
cana, recognized the unusual structure of the prosternum and anterior 
coxae, and the segregation of this genus (and certain others) on this 
character aids greatly in the study of the Lispinini (the Lispini of 
most writers). 
I have examined six species that must at present be placed in this 
genus. hese all occur in the Western Hemisphere with the excep- 
tion of an undescribed species from central Africa. P. exiguus
