absence of the two short stride. Dr. Horn in Trans. Am. Ent. Soc, 

 vol. XIX, p. 211, says that the species of this genus have eleven 

 striae on each elytron, seven between the suture and the umbo and 

 two parallel with the side margin. Between these two series, just 

 exterior to the seventh, are two short striae, which may be regular or 

 confused. Dr. Horn evidently did not count the short scutellar nor 

 the marginal stria. With a few exceptions the stria next to the 

 marginal one is rarely entire, it generally joins the marginal stria 

 about middle or the basal part a little above middle and the apical 

 part a little below middle. 



Metachroma novemstriatum new species. 



Oblong, shining, above yellowish-testaceous, prothorax a little darker; 

 each elytron with two darker spots, one above middle, between the fourth and 

 fifth striae, the other below middle and between the sixth and seventh striae ; 

 body beneath dark brown ; antennas pale. Head sparsely punctate, occiput more 

 coarsely punctate ; clypeus moderately coarsely punctate ; frontal impression 

 distinct ; clypeo-frontal suture obliterated. Prothorax a little wider than long ; 

 sides moderately arcuate ; apical and basal angles prominent ; surface mod- 

 erately coarsely punctate, punctures finer near apical, lateral and basal mar- 

 gins. Elytra a little longer than wide across the middle ; striate-punctate, 

 striae regular, short striae absent ; intervals very feebly punctate. Propleurae 

 without punctures. Body beneath sparsely punctate ; met-episterna smooth ; 

 posterior femora with a very small denticle. Length 3.75 mm.

Colaspis subsenea new species. 



Form and size of C. brunnea; shining; upper surface brown with dis- 

 tinct metallic tint ; below and legs slightly paler, except metasternum, which 

 is darker and with metallic tint ; labruni, palpi and antennae flavous, the 

 seventh, tenth and eleventh joints of the latter black. Head rather sparsely, 

 not coarsely punctate ; epistoma more coarsely and closely punctate. Pro- 

 thorax moderately closely punctate at sides, punctures finer on the disk, sides 

 feebly arcuate from base to a little above middle, then more strongly narrow- 

 ing towards apex ; apical angles obtuse ; basal angles prominent. Elytra 

 scarcely wider at base than the prothorax ; punctuation coarse and rather con- 

 fused in about basal half; more regular from the middle towards apex where 

 the intervals are more or less distinct and subcostate near apex; sutural angles 

 acute, slightly prominent. Propleurae, metasternum and ventral segments 

 sparsely punctate. Length 4 mm.
