SCUDDER ON FOSSIL INSECTS. 763 



ered profusely with slight asperities or a coarse pile (much perhaps as in 

 Endecatomus rugosus). The elytra, which are nearly three times as long 

 as broad, and taper regularly from near the base to near the tip, show 

 no mark of such asperities, bat are profusely punctate in black, made up 

 of scattered punctse, about 0.03™'"-' in diameter, not altogether irregularly 

 disposed, although at first sight having that appearance, but showing 

 in many places, not uniformly, signs of a longitudinal distribution into 

 from fourteen to sixteen rows. The elytra, indeed, resemble those of 

 Bostrychus capucinus (Linn.), but I am not aware that similar markings 

 occur on smaller Ptinidce. 



Length of body 4.3""° 5 breadth of same 2""°; length of elytra 3.15""". 



Anobium f deceptum. — Another specimen (IS'o. 4086), representing an 

 elytron only, evidently belongs to the same genus as the last, and at first 

 sight appeared to be of the same species, as it belongs to an insect of the 

 same size, and the punctures on the elytra are similarly disposed ; they 

 are, however, if anything, more thickly crowded, so as to form about 

 eighteen rows in the rather broader elytron ; and not only is the elytron' 

 broader and shorter than in the preceding species, being less than twO' 

 and a half times longer than broad, but it scarcely tapers at all in the 

 basal three fifths, and beyond that more rapidly than in the species 

 last described. 



Length of elytron 3"'" ; breadth of same 1.25""". 



Anobium lignitum. — A third species of this family, with irregularly 

 punctate elytra, is represented by a single specimen (No. 4082), giving, 

 a dorsal view of pronotum and elytra. It differs generically from 

 the two preceding species, and agrees better with Anobium proper in 

 having a more gibbous and less conical j^rothorax, and in having, 

 the sides of the elytra parallel through most of their extent. It is cou= 

 siderably smaller than either of the preceding species. The prothorax- 

 is one-third the length of the body, minutely punctate and scabrous,, 

 tapering only a little in its basal and considerably in its anterior half, 

 the front well rounded. The elytra are about two and a half times 

 longer than broad, equal on the basal two-thirds, and then rounding, 

 rapidly inward, so that the posterior outline of the body is more broadly 

 rounded than the anterior outline ; the elytra are profusely punctate- 

 with little pits, averaging scarcely more than 0.02"'"' in diameter, dis- 

 tributed at pretty regular intervals, but not forming anything like longi- 

 tudinal series, and so near together as to be equivalent to about fourteen, 

 rows. The whole body is uniformly black. 



Length of body 3.75™"', of elytra 2.5""" 5 width of body 1.9""^,

Mycofretusbinotata. — A single specimen with its reverse (Nos. 3990, 

 4015) represent the dorsal aspect of this species, which closely resembles 

 If. scmguinipennis Lac. in shape. It is, however, a little smaller, the
