Head with a subcircular impression in middle, with a 

 narrow impression from same to base; with irregularly distri- 

 buted and rather small punctures; clypeus with narrow, 

 oblique sutures, almost meeting posteriorly at the median im- 

 pression. Antennae not very thin, scarcely extending to hind 

 coxae, second joint about half the length of third ; third, fifth, 

 and seventh each a trifle longer than the fourth, sixth, and 

 eighth. Prothorax widely transverse, sides oblique, and 

 strongly increasing in width from apex to base, margins narrow 

 in front, rapidly becoming wider to base ; with minute, scat- 

 tered punctures, and some larger ones, but still small, towards 

 sides. Elytra almost parallel-sided to near apex, base slightly 

 narrower than base of prothorax ; with irregular double or 

 semi-double rows of not very large punctures, becoming con- 

 densed into single rows posteriorly ; interstices between same 

 more or less distinctly elevated, and themselves with small 

 punctures. Fifth segment of ahdomen slightly upcurved in 

 middle. Front femora strongly dentate. Length, 8 mm.

 collection). Type, I. 3413. 



The prothorax is remarkable. The basal joint of the 

 middle tarsi is slightly larger than on the front pair, and 

 slightly smaller than on the hind pair, a reversal of the usual 

 proportions. Two of the interstices on each elytron, in addi- 

 tion to being slightly elevated above their fellows, are also 

 each supplied with a narrow median ridge, quite distinct from 

 some directions. The flanks of the prosternum are highly 

 polished, but from some directions light striae become visible. 

 The type is probably a female. 



Prypnocolaspis submetallica, n. sp. 



Black with a slight metallic gloss, bluish on head and 

 prothorax, brassy on elytra, and greenish on parts of under- 

 surface ; front angles of prothorax, front of clypeus, labrum, 

 four basal joints of antennae, and base of each of the three 

 next, palpi (tips excepted), and legs (knees, tarsi, and tips of 

 tibiae excepted) more or less reddish. 



Head with a rather wide, shallow, median impression, 

 feebly connected with the base; with irregularly distributed 

 punctures of moderate size or small, and slightly denser on 

 clypeus (whose lateral sutures are oblique) than elsewhere. 

 Antennae extending to hind coxae, second joint about half 

 the length of third, the latter equal to fourth, fifth to eighth 

 and the eleventh subequal in length and a trifle longer than 

 the ninth and tenth. Prothorax at base (which is lightly 

 bisinuate) about thrice as wide as the median length, sides
