— . Vortex and ba'^c of tlic froT)t iiarrower; clytral arcoles more 

 varieiiated and minutely dotted with pale in the darker areas; 

 inhabits the West Indies, iuiricala Uhler. 



Catonia fusca n. s<i'. 



Form and size of grisea; fuscous brown; elytra unicolorous dotted 

 with white; front banded. Length 5\ mm. 



Vertex short, transverse, brown with pale carina?, anterior and 

 posterior margins parallel, hardly arcuated. Front about as in 

 im'punctaia ; rather broad and but little narrowed basally, the carinae 

 strong, the marginal well elevated ; whitish tinged with fulvous brown 

 on the base and toward the apex of the clypeus ; crossed by two broad 

 black bands; margins scarcely dotted toward their base. Antennae 

 brown with their seta black. Pronotum blackish with pale carinse, 

 the lateral concentric as in all the species know^n to me, with about 

 three branches to the hind margin. Mesonotum fulvous with the three 

 straight parallel carina^ and extreme apex pale, the carinse margined 

 with fuscous. Elytra uniformly smoky brown, a little paler toward the 

 margins, nervures pale toward the apex, areoles dotted with pale. 

 Abdomen with pale segmental margins; pleural pieces fuscous varied 

 with pale. Legs pale brown, becoming a little darker at the knees. 



Described from one female specimen collected in San Mateo County, 

 California, by a Mr. Coleman. 



Catonia nava Say. 



This is a somewhat larger and darker species than grisea, with the 

 front strongly narrowed basally; base brown minutely irrorated with 

 paler, followed by a white transverse median band and then a blackish 

 band next the base of the pale clypeus; the marginal carinse dotted 

 with pale. Mesonotum tinged with fulvous with a large blackish 

 central cloud. The elytra quite strongly variegated and dotted on the 

 nervures. I have taken this species at Hamburg and Gowanda, New 

 York, and have seen others from the Eastern States. 



Catonia cinctifrons Fitch. 



I have not yet seen anything that just answers to the description 

 given by Fitch, but this seems to be a good species very near to iiava 

 and is perhaps Say's variety "a" of that species. 



Catonia picta n. sp. 



Allied to nava and cinctifrons. Face white with two black bands; 

 mesonotum rufopiceous; elytra obscurely banded. Length 5^ mm. 



Front broad, but slightly narrowed at base ; clypeus short, conical, and 

 with the front tricarinate,the lateral carinae marginal, strongly elevated.
