subfamily being the folding inwards of the genal processes and their close adpression so 
as to cover the maxilla. The only character that Paraphleus possesses to distinguish it 
from the Lwmophici is the four-jointed feet. I do not attach great importance to this 
peculiarity, because it is evident that the number of tarsal joints is in this family much 
less important than it usually is in Coleoptera. When the basal joint of the tarsus is 
so extremely short as to leave it doubtful whether it exists or not, it is evidently a 
bad character to rely on. This is well shown by the difference of opinion that has 
existed for many years as to whether Prostomis has four- or five-jointed tarsi. Hence 
I entertain but little doubt that Paraphlwus is really closely allied to Lemophiqus, 
although I believe the tarsal formula to be different in the two genera. 
1. Paraphleus crassiceps, sp.n. (Tab. XVI. fig. 7.) 
Angustus, sublinearis, capite majore; nigricans, elytris pedibusque testaceis, antennis mandibulisque sordide 
testaceis ; prothorace utrinque carinula subtili ornato ; elytris subtilissime costato-striatis. 
Long. 23 millim. 
Hab. Guatemaua, San Gerénimo (Champion). 
Antenne rather short, stout, first joint somewhat elongate, second inserted on one of 
the angles of the first, terminal three joints slightly thickened. Head large, mandibles 
elongate; epistome prolonged, narrowed towards the front, rounded at the apex ; 
extending from the base of the antenna to near the back of the head there is on each 
side a fine straight carina; the surface is finely and not closely punctate. Thorax 
elongate, distinctly narrowed behind, finely punctate; the lateral margin can be 
distinguished near the base, though very fine; an extremely fine, quite straight line 
runs from the front margin to the hind angle; there is a very minute fovea on the 
middle near the front. The elytra are elongate and narrow, and are traversed by three 
very fine coste. The legs are slender, the tarsi very slender. ‘Three specimens. 
2. Paraphleus longicollis, sp. n. (Tab. XVI. fig. 8.) 
Angustus, linearis, subdepressus, ferrugineus ; prothorace perelongato, tenuissime costato, nitido, parcissime 
punctato ; elytris sublevigatis, obsolete costatis. 
Long. vix 2 millim. 
Hab. GuateMa.a, Zapote (Champion). 
Epistome prolonged, truncate in front. Antenne rather short and feeble, first joint 
globular, terminal three joints a little incrassate. From the base of the antenna there 
extends backwards a very delicate carina; the surface of the head is shining, very 
sparingly punctate. Thorax very long, nearly parallel, but perceptibly narrowed 
behind, the lateral margin very fine, and parallel with it an extremely fine costa 
extending from apex to base, punctuation fine and scanty. LHlytra very narrow, very 
obsoletely costate, so that they appear almost smooth. One specimen. 
This little insect is not likely to be considered congeneric with P. crassiceps,
