FOSSIL COLEOPTEEA 



ECTOPRIA Lec. 



15 



E. LATICOLLIS n. sp. (Plate III, Fig. 8.) Form, allowing for flattening, 

 similar to that of the recent E. nervosa. The head is somewhat damaged, 

 the front outline broken, but the eyes are of moderate size and the antennae, 

 only one of which is preserved, are filiform, though the poor state of 

 preservation precludes any description of the individual joints. Prothorax 

 short, deeply emarginate in front, anterior angles sharp, base bisinuate. 

 Scutellum small. Elytra, at base, about the same width as the prothorax, 

 approximately one-fourth longer than their conjoint basal width. Sculpture 

 of the entire upper surface minute and with a covering of fine hairs. 

 Length, 3.85 mm. 



It seems that the DascvllidEe offer the best family agreement 

 with this fossil, and it is placed provisionally in Ecfopria since 

 the proportions of the body, the antenna and the coxal structures 

 correspond fairly well. The Dascyllidae would seldom make sat- 

 isfactor.y fossils, their fragility renders perfect preservation un- 

 likely, and the generic characters rest largely upon structures 

 which would scarcely ever be in condition for study. 



Hydnocera Ncicm. 



H. AVOLCOTTi n. sp. (Plate IV, Fig. 11.) Form rather stout. Head 

 short and broad, and, including the eyes, probably a little wider than the 

 prothorax, sculpture extremely minute, consisting only of a fine alutaceous 

 roughening. Antennae not well preserved, but the club seems fairly distinct. 

 Prothorax very broad, about one and a half times as wide as long, the sides 

 not entirely perfect but evidently narrowing to the base, a strong transverse 

 anterior impressed line, surface similar to that of the head. Seutellimi 

 moderate, triangular. Elytra much shorter than the abdomen, not striate, 

 but strongly sparsely punctate towards the apices which are somewhat nar- 

 rowed and separately rounded as well as distinctly beaded. Abdomen ex- 

 posing at least four segments behind the elytral tips, sutures strongly sin- 

 uate, projecting backwards at middle. The dorsal ventral segments are 

 without any well defined sculpture. Legs stout. Length, 5.35 mm. 



Not particularly closely related to any of the numerous living 

 North and Central American species with which I am acquainted. 

 The exposed portion of the abdomen seems excessively long, but 

 this is doubtless due in part to maceration before fossilization. 

 The prothorax is like that of H. pubescens in the deep anterior 

 impression, but is relatively broader and of different shape. The 

 margined or beaded elytra recall those of H. longicolUs or H. 

 tabida, but are differently sculptured. The restriction of the
