250 PHALACRIDZ. 
Hab. Mexico, Jalapa (Hoge), Teapa (H. H. Smith); Brrrtsa Honpuras (Blanca- 
neaux); GUATEMALA, Duefias (Champion). 
Antenne clear yellow, the club rather slender. Thorax feebly lobed, margined only 
along the lobe. LElytra with obscure silky texture of the surface, without distinct 
punctuation, but with very obsolete subtransverse punctures presenting a somewhat 
serial arrangement. 
The prosternum is rather flat, somewhat large, very shining; the metasternum very 
prominent in front, strongly margined, and the angles of the margin rounded. The 
basal joint of the hind tarsus is very short, the second joint three times as long as 
the first. 
This species is rather smaller than O. guatemalenus, and is well distinguished by the 
somewhat different structure of the breast; on the upper surface the absence of distinct 
serial punctures and of a basal margin to the thorax are the best characters for 
distinguishing it. We have received fifteen examples from Mexico, and one each 
from British Honduras and Guatemala. 
6. Olibrus partitus, sp. n. 
Ovalis, minus convexus, piceo-testaceus, supra piceus, antennis, pedibus elytrorumque dimidio posteriore 
testaceis. 
Long. 2 millim. 
Hab. GuaTEMALA, Chiacam, Lanquin (Champion). 
Antenne clear yellow, with a slender club. Thorax margined at the base in the 
middle. Elytra with elongate sutural stria, but almost destitute of other sculpture. 
Legs slender. 
This distinct little Olidrus varies somewhat in depth of colour like many of its 
congeners. 
7. Olibrus posticalis, sp. n. 
Breviter ovalis, sat convexus, rufo-testaceus, supra piceus, elytris apicem versus dilutioribus; illis stria suturali 
seriebusque abbreviatis punctorum minus subtilibus. 
Long. 13 millim. 
Hab. GuatEeMALA, Champerico (Champion). 
Var. Elytrorum punctis seriatis plus minusve obsoletescentibus. 
Hab. Muxico, Cordova (Sallé), San Juan Bautista in Tabasco (Hége), Teapa, Atoyac 
(H. H, Smith). 
A very small insect, and apparently an Olibrus, but possessing an unusually broad 
scutellum, and remarkable also on account of the distinct serial punctures. The 
sutural stria becomes in front a series of quite evident punctures, not, however, quite 
attaining the base, and outside this there are two or three other series of punc-
