248 PHALACRIDA. 
7. Phalacrus lucidus, sp. n. 
Breviter ovalis, latus, minus convexus, dilute rufus, antennis pedibusque testaceis. 
Long. 2 millim. 
Hab. GuateMmata, Capetillo (Champion). 
Closely allied to P. scutedlaris, though easily distinguished from it by the colour and 
smaller size. The club of the antenna is of the same peculiar shape as, though much 
shorter than, it is in P. scutellaris, that is to say, the increase in size of the terminal 
_ joints is chiefly on one side of the mesial line. Unique. | 
OLIBRUS. 
Olibrus, Erichson, Nat. Ins. Deutsch. iii. p. 118 (1848). 
This is the most extensive of the genera of Phalacride, and comprises forty or fifty 
known species, which represent quite one half of the family. It is widely distributed, 
having been recorded from various parts of the eastern hemisphere, and being well 
represented in North America; from South America only one species has as yet been 
recorded. A portion of the species placed in the genus must, however, be separated, 
as Erichson included Fusé¢ilbus in it. 
Our representatives differ somewhat in their structural details from one another and 
from the European species, but I have not found it necessary to divide them into more 
than one genus on this account. 
1. Olibrus guatemalenus, sp. n. 
Testaceus, supra niger, vix subznescens, breviter ovalis, convexus ; elytris seriatim subtiliter punctatis, inter- 
stitiis obsoletissime punctulatis. 
Long. 24 millim. 
Hab. GuateMaLa, Zapote, San Gerénimo, Cahabon, Chiacam (Champion); Panama, 
Volcan de Chiriqui 3000 to 4000 feet (Champion). 
Antenne yellow ; club rather large, its terminal joint rather short. Thorax distinctly 
- and completely margined at the base, scarcely lobed in the middle. Scutellum quite 
small. Elytra with distinct and quite regular series of fine punctures extending almost 
to the base, the interstices indistinctly punctured. 
We have received a small series of this species, including a pair from the State of 
Panama. ‘The upper surface is sometimes piceous rather than black. 
2. Olibrus vulgaris, sp. n. 
Rotundato-ovalis, sat convexus, nitidus, rufescens, supra dilute piceus, antennis pedibusque testaceis; elytris 
seriatim subtilissime punctatis. 
Long. 2 millim. 
Hab. GuaTEMALA, Chacoj and Chiacam in Vera Paz (Champion).
