Tribe IV. MAIJ.( )I >KV1 Xl. 



This tribe is also fc|)i'cscntc(l by the sin^'lc iicnus Mallodnja 

 Horn, formed L'or a "rather incons])icuous species, il/. subanica 

 Horn, resembling a dei)ressed Mihnulfjid or an EiiniKsd. from 

 which it differs by the slender tarsi, the penultimate joint not being 

 excavate-emarginate and the front tarsi not dilated in the males." 

 It is oblong, pieeous, with faint a?neous surface lustre, and 6 to 8.5 

 mm. in length. The types were taken liy Dury near Cincinnati, 

 who found them rather abundant on the lu'anches of dead honey- 

 locust. It probably occurs in the southeastern part of Indiana, but 

 no specimen has been seen from the State.

Rather small oval, convex forms, having the head vertically de- 

 flexed; antenna^ 11 -jointed, the joints gradual! \' thickened, except 

 in MicroscapJia, where they end in a distinct club; front coxffi oval, 

 separated by the prosternum; tarsi filiform, claws simple. Four of 

 the tive genera, recognized by Horn as com])osiug the tribe, are 

 known to i)e represented in the State, while the single species of the 

 other may occur.
