Disonycha quinquerutata new species. 



Above flavous ; head behind the eyes slightly darker, antennae except the 

 first joint below, two transverse spots on prothorax, a little above middle, 

 scutellum, a sutural, discal and marginal vittas black, the discal vitta narrower 

 than the pale space on each side ; a short line below the two discal spots on 

 the prothorax and a more or less distinct larger lateral spot castaneous ; body 

 below pale except metasternum, posterior femora and tibiae at apex and tarsi 

 black. 



Head shining, moderately coarsely punctate near each eye, median part 

 smooth ; tubercles distinct and slightly darker ; antennas long, reaching beyond 

 the middle of elytra, joints rather narrow, third joint about twice as long as 

 second, fourth about as long as second and third together, from the fourth 

 slowly decreasing in length. Prothorax about twice as wide as long ; sides 

 feebly arcuately narrowing to apex; basal angles rounded; apical angles feebly 

 thickened, oblique ; surface smooth, shining. Elytra at base a little wider than 

 the prothorax at base ; sides feebly arcuate ; surface minutely obsoletely punc- 

 tate. Ventral segments of abdomen very densely and finely punctate ; pubes- 

 cence moderately long and dense. Length 5.75 mm.

 Chr. Weidt). 



I received this species as crenicollis (fumata Lee?) from Prof. 

 Snow, near which it has to be placed. The form is slightly narrower, 

 the antennae longer and the coloration is different. The Utah speci- 

 men I bought some years ago from J. Chr. Weidt with the above 

 name attached to it and supposed to be given by Dr. Horn, who identi- 

 fied some of his material. 



Disonycha latifrons new species. 



Above flavous ; head behind the eyes, labrum, antennae, except the first 

 joint below, two transverse spots on prothorax a little above middle, scutellum 

 and a sutural, discal and marginal vittae black, the discal vitta narrower than 

 the pale space on each side ; body below black, except underside of prothorax, 

 median part of mesosternum, and apex of penultimate and last ventral segment 

 flavous ; femora reddish-yellow, without black line above ; tibiae and tarsi black. 



Head smooth, shining, a few punctures near each eye ; frontal tubercles 

 indistinct, the space between the antennal insertion and apex scarcely convex; 

 antennas reaching to about middle of elytra, third joint longer than second but 

 distinctly shorter than fourth, from the fourth gradually decreasing in length. 

 Prothorax about twice as wide as long ; sides* feebly arcuately narrowing to 

 apex; basal angles obtuse, feebly rounded; apical angles slightly thickened 

 and a little prominent ; surface smooth, shining. Elytra at base scarcely 

 wider than the prothorax; sides feebly arcuate; surface minutely reticulate
