Metacolaspis conspersa n. sp. 



Form moderately robust, general color pale yellowish- 

 white, antennge, metapectus, tibiae and tarsi piceous; ely- 

 tra brown with numerous yellowish-white spots usually 

 small, irregularly placed, surface glabrous. Head smooth. 

 Thorax one-half wider than long, sides feebly arcuate, 

 front angles distinct, hind angles obtuse, surface polished 

 with numerous moderately coarse punctures at the sides. 

 Scutellum smooth. Elytra wider at base than the thorax, 

 about one-third longer than wide, sides feebly arcuate, disc 

 convex with closely placed deep punctures, substriately 

 arranged with three faintly indicated costge. Body beneath 

 smooth, sides of metapectus finely punctate and pubes- 

 cent. Length, .16 inch; 4 mm.

COLASPIS MCESTA n. Sp. 



Form robust, piceous, upper surface feebly, dark- 

 bronzed, moderately shining. Antennae piceous, the basal 

 five joints gradually paler. Head punctate, less closely 

 on the occiput. Thorax twice as wide as long, narrower 

 in front, sides broadly arcuate, scarcely undulate, margin 

 narrowly reflexed, disc convex, finely punctate, but more 

 coarsely at sides. Elytra very little wider than the thorax, 

 disc vaguely subcostate near the apex, surface moderately 

 coarsely, irregularly, not densely punctate. Body be- 

 neath very sparsely punctate. Legs piceous, the front and 

 middle femora and all the coxse slightly paler. Length, 

 .25 inch; 6.5 mm. 



Similar in form to Rhabdo^terus pici-pes, but larger and 

 more robust. It seems most nearly related in our fauna 

 to C . nigrocyanea, and like that species has the proster- 

 num rather wider than in the other Colaspis.
