Pronotum punctured about like the head except on the middle area where 

 it is extremely minutely but distinctly and sparsely granulate, the gran- 

 ules scattering, not arranged in rows. Elytra evenly and minutely punctu- 

 late like the head, not striate excepting possibly one or two lines near the 

 outer margin. Underside with small, close, vague, shallow punctures a 

 little larger than those of the head. Legs short. Length, exclusive of 

 extruded sex organ, 4.85 mm. 



Described from one specimen with counterpart. 



Compared with the described Florissant fossil Anobiinae, this 

 beetle separates from all of them by the broad form, circular eyes 

 and type of sculpture. As to affinities with recent forms, it 

 appears to belong to LeConte's subgroup 2, Anobia, by the 

 strongly deflexed head, resting upon the under surface of the 

 prothorax. The first ventral seems not to be excavate for the re- 

 ception of the hind legs, the metasternum neither excavate nor 

 lobed in front. This is as far as the analysis can be carried 

 through the generic table since the antennae are not 

 well shown, but the non-clavate thighs, lack of hairy 

 vestiture, separate abdominal segments and nonstriate 

 elytra appear to exclude Ptinodes, Hadrohregmus, Gast- 

 rallus, Trichodesma and Nicohium.. The antennae are seen to lie 

 on the front coxae, vrhich are contiguous or nearly so. My 

 opinion, therefore, is that the beetle belongs with Sitodrepa and 

 Oligomerus, agreeing with them in the large eyes, as well as in 

 the other characters noted. It differs from Sitodrepa in having 

 the middle coxae absolutely contiguous, but agrees with Oli- 

 gomerus in that particular. The finely punctate non-striate 

 elytra, however, are foreign to the latter genus, as far as my ex- 

 perience goes.. Relatively to the head and prothorax, the present 

 species has a much shorter hind body than the Florissant 0. 

 {f) duraius, which has a similar, though not identical type of 

 sculpture. Quite probably the two are congeneric, even if not 

 truly belonging to Oligomerus. 



LACHNOSTEENA (?) EXTINCTA sp. nov. 

 (Plate I, fig. 5). 



Eepresented by a wing cover only, in good preservation. It is very finely 

 and deeply but sparsely and somewhat irregularly punctured, the punctures 

 partially outlining four smoother areas which correspond to the costae seen 

 on the elytra of many recent Lachnosterna. Along the sutural margin is 

 3- strong stria while the outer margin towards the apex has a much less
