LITHOCHARIS (p. 549). 
1(4). Lithocharis curviceps. 
Nigra, antennis pedibus elytrisque fusco-testaceis, his disco fuscescente ; capite prothoraceque subtiliter punc- 
tatis, medio nitidulis. 
Long. 5 millim. 
Hab. Mexico, near the city, Amecameca, Toluca, Huitzo (Hoge). 
Antenne rather large. Head distinctly emarginate behind, black ; densely and very 
minutely punctate except on the disc, where the punctures are more distant, so that 
this part is shining. Thorax about as long as broad, black, very minutely punctate ; 
the punctures are more distant on the disc, and there is a very slender shining space 
along the middle. Elytra much longer than the thorax, densely and finely punctate, 
slightly shining. Hind body extremely finely punctate. Male unknown. 
Distinguished from L. mendax by the head being a little emarginate behind. 
EUSTILICUS (p. 579). 
Eustilicus mexicanus (p. 580). 
To the Mexican locality given, add :—Cuernavaca in Morelos (Flohr). 
TROCHODERUS (p. 580). 
3. Trochoderus ovaticeps. 
Ferrugineus, capite fusco-ferrugineo, pedibus testaceis, dense subtilissime punctatus, opacus ; prothorace medio 
linea levigata nitida. 
Long. 7 millim. 
Hab. Mexico, La Noria in Sinaloa (Hoge). 
Head oval, very densely punctured, dull, darker in colour than the other parts. 
Thorax about as long as broad, very greatly narrowed in front, densely and finely 
granulose, dull, with a slender smooth space along the middle. Elytra longer than the 
thorax, densely punctate. 
We have received only one female of this insect. In addition to being of a brighter 
colour than the other species of the genus, it has a considerably narrower head. 
SUNIOCHARIS (p. 586). 
Suniocharis fragilis (p. 587). 
To the Mexican locality given, add:—Acapulco in Guerrero (Hége). 
An example recently captured by Herr Hoge at Acapulco has the head quite pale, 
but does not apparently differ in any character of specific importance from the type.
