Mandibles projecting, moderately long. Mentum bluntly angulate anteriorly 

 in the middle, its face rather coarsely but not deeply punctured. Prester- 

 num strongly separating the coxae, its sculpture and that of the remainder 

 of the underside obscure but certainly not deep. Elytra exposed only on the 

 edges and showing from beneath but exhibiting portions of two or three 

 close rows of large punctures, rounded in form and separated by much less 

 than their own diameters. Legs short and stout, the middle tibiae, which 

 are the best preserved, each showing a row of close, rather long spines along 

 the posterior edge. Length, 6.00 mm. 

 Described from one specimen. 



Numerous characters are shown which point to the Nitidulidae 

 as a family reference. These are the general form, prominent 

 mandibles, capitate antennae (which, however, are poorly pre- 

 served), form of the mentum, position of antennal grooves, trans- 

 verse front coxae separated by the moderately wide prosternum, 

 non-truncate elytra and short legs with fringed tibiae. The 

 beetle is above the average size of recent Nitidulidae but no larger 

 than Phenolia grossa with which it has been compared. 



MALACHIUS PEISTINUS sp. nov. 

 (Plate IV, fig. 26). 



Form, as preserved, more elongate than in recent species of this genus, 

 but from the position in which the specimen lies and the condition of the 

 edges it is probable that the full width is not shown. Head of moderate 

 size. Eye rather large, rounded. Antenna imperfectly preserved but show- 

 ing about six rather long pectinations fairly well, from which it may be 

 inferred that the individual was a male. Prothorax too badly crushed for 

 description. Elytra about three and one-half times the prothoracic length, 

 finely roughened and with some scattered punctures showing in places. 

 Abdominal segmentation about equal. Legs wanting. Length, from front 

 of head to elytral apex, 4.75 mm. 



Described from one specimen. 



Undoubtedly a Malachius or an allied type and, in a general 

 way, similar to the living American forms of that genus. These 

 very soft and fragile insects are seldom very well preserved and 

 the present specimen is not perfect enough to allow of more 

 specific comparisons. 



OLIGOMERUS BREVIUSCULUS sp. nov. 

 (Plate I, fig. 6). 



Form moderately elongate, the insect as a whole one and five-sixths times 

 as long as wide. Head bent under the pronotum, front extremely minutely, 

 closely and moderately deeply punctured and alutaceous. Eyes circular, 

 separated by about twice their own width. Antennae not shown in detail.
