PTINUS. 195 
pone medium magis approximatis, duobus transversis paulo post hee majoribus inter suturam et marginem 
eequidistantibus. Thorax in medio pilis nigris, elytra pilis nigris brunneisque obsita. Long. 24-3 
millim. ¢ 9. 
Mas. Antennis quam corpus longioribus ; oculis magnis, subglobosis. 
Femina. Antennis corporis longitudine. 
Hab. Panama, David, Tolé (Champion). 
The general colour of this insect is pitchy brown; but it is much varied with greyish 
white and brown pubescence. The breast, especially at the sides, is thickly clothed 
with white depressed hairs. The prominence of the eyes in the male reminds one of 
Aylophilus. The two middle tubercles on the thorax are very close, and when viewed 
sideways appear as one; there are usually a few white hairs at the base of each on the 
outside. The elytra have longer and shorter upright hairs and six white spots of 
depressed scales, the four anterior being nearer to the suture than the two subapical 
larger ones are. | | 
A series of specimens of equal number of both sexes of this species were taken by 
Champion at David, Chiriqui. I have only yet seen a single specimen from Tolé. 
3. Ptinus coarctatus. 
_ Oblongus, fuscus ; thorace ad basin disci carinulis tribus parum elevatis, postice valde coarctato ; elytris fuscis 
profunde punctato-striatis, pilis brunneis undique obsitis; basi apiceque pube cinerea, antice lineas duas 
obliquas, postice in sutura litteram x formante vestitis. Long. 3 millim. ¢ 2. 
Mas. Oculis majoribus subglobosis, quam thorax latioribus. 
Hab. Mexico, Cerro de Plumas (Hége); Guatmemata, San Gerénimo, Capetillo, 
Duefias (Champion). 
Allied to the preceding; differs in the thoracic carine, antenne shorter in the male, 
absence of the white spots, &c. 
Two specimens are all that have come under my notice from Mexico; but one 
from Capetillo in Guatemala may, I think, belong to the same species, and one from 
each of San Gerénimo and Duefias must also, I think, be assigned to it. 
4, Ptinus lateralis. (Tab. X. fig. 6.) 
Oblongus, rufo-brunneus, pilosus; capite, thorace, pedibus basi elytrisque plaga magna laterali suturam haud 
attingente nigro-fuscis; thorace postice valde constricto; elytris fortiter punctato-striatis. Long. 
3 millim. 
Hab. Guatemata, Calderas (Champion). 
Head with the eyes very little wider than the widest part of the thorax, not very 
prominent, crown with a double tuft of pilose hairs. Thorax with the part in front of the 
constriction wider than long, below the constriction widened again at the base, clothed 
with coarse and irregular pile. Elytra denuded at the base for some way down the 
suture, with series of large squarish punctures similar to those in P. coarctatus.
