EUMALUS.—LEPTOCHIRUS. 733: 
Eleusis is here presented in a still more conspicuous manner. I am not acquainted 
with any species of the genus other than the two here described, but it is probable that 
the North-American [somalus nigrellus, Lec., belongs to it. 
1. Kumalus strigosus. (Tab. XIX. fig. 20.) 
Hlongatus, niger ; antennarum basi, pedibus elytrorumque apice rufis; strigosus, haud punctatus. 
Long. 4 millim. 
Hab. Guatemaa, Totonicapam 8500 to 10,500 feet (Champion). 
Antenne with the three basal joints red, the third joint rather shorter than the 
second. Head with a longitudinal elevation on either side in continuation with the 
antennary tubercles. Thorax elongate, much narrowed behind, canaliculate along the 
middle ; with four elevations on the front margin, the outer elevation being more elongate 
than the others. Elytra elongate; quite impunctate, but delicately strigose. Fourteen 
examples, exhibiting no variation. 
2. Kumalus nigriceps, (Tab. XIX. fig. 21.) 
Rufo-testaceus ; capite nigro, abdomine nigro-fusco ; subtiliter strigosus, haud punctatus. 
Long. 23 millim. 
Hab. GuatTEMALA, Capetillo (Champion). 
Antenne yellow, short, scarcely thicker externally; third joint rather smaller than 
the second. Head narrow, longitudinally bi-impressed. Thorax longer than broad, 
finely canaliculate along the middle, feebly plico-tuberculate on the front margin; 
delicately strigose, without punctures. Elytra elongate and narrow, delicately strigose, 
without any punctures. Five examples. 
Group LEPTOCHIRINA. 
The genus Leptochirus and its allies having the anterior acetabula closed behind by 
the junction of the prothoracic side-pieces with a process of the prosternum, they must be 
separated into a distinct group. The separation of this group and the “ Eleusinina ” from 
the “ Piestina” will be found greatly to facilitate an improved arrangement of the 
*“‘Oxytelina” and “ Piestina.” 
LEPTOCHIRUS. 
Leptochirus, Germar, Ins. spec. nov. p. 35 (1824); Erichson, Gen. et Spec. Staph. p. 824 (1840). 
This genus, after the abstraction of Priochirus, will be defined by the existence of a 
conspicuous prosternal process behind the anterior coxe, and by the apices of the coxe 
not being exserted. It will comprise all the New-World species of Leptochirus hitherto 
described, except L. dicornis, and will also include for the present two or three species 
of the eastern hemisphere, viz. L. laticeps, Er., L. guadridens, Motsch., and L. ide, Kr. 
The New-World species of the genus are greatly in need of a thorough revision; the
