have the promment outer angle above the middle. There is also a 

 slight suggestion of certain members of the curious Hawaiian Pro- 

 terhinidae, particularly Proterhinus Jcaalae Perkins.

ANHYDROPHILUS BRODIEI Handlirsch. 



Lias (Brodie). Lacoe Coll. 3499 (Cracombe, Worcestershire), 3443, 

 3444, 3445, 3446, 3470 (Wamlode Cliff, Gloucestershu-e) . Elytra 

 about 4.75 mm. long, elongate-oval, convex, apex rather obtuse; 

 sculpture almost lacking, but there were apparently very -faint 

 widely spaced striae. So far as anything shows, the insect could be 

 closely allied to Agabus. 



ELATEROPHANES SOCIUS (Giebel). 

 Plate 01, fig. 2. 



Lias (Brodie). Lacoe Coll. 3441, 3434, 3439; all from Wainlode 

 Cliff, Lower Lias. Brodie figured a specimen showing the thorax; 

 those before me are elytra. They agree well with the modern 

 Elateridae, e. g., Monocrepidius. There are eight longitudinal 

 striae. The length of an elytron is 6.2 mm. 



Westwood's figure, pubhshed by Brodie, actually shows the an- 

 tennal grooves on the under side of the thorax, and leaves no doubt 

 that the Elateridae were fully differentiated as early as the Lias. 



Plesiotype.— Cat. No. 61400, U.S.N.M. 



ELATEROPHANES ACUTUS, new species. 

 Plate 61, fig. 1. 



Elytron 5 mm. long, about 1.5 broad in middle, as preserved dark 

 coffee brown; striae as in E. socius, but faint. Compared with E. 

 socius, the elytron is broader in proportion to its length and the apex 

 is more acute. The specimen shows the inner surface.

PSEUDOTELEPHORUS KAUERI (Giebel). 



Lias (Brodie). Lacoe Coll. 3480. From the Lower Lias. In the 

 list accompanying the specimens it is marked "Telephoridae." In 

 addition to the very numerous fine punctures (appearing as brown 

 dots), there are about 10 very delicate striae. The insect is evidently 

 not closely related to Teleplorus. (Cat. No. 61402, U.S.N.M.) 



The two foUowing species, also marked "Telephoridae" in the list, 

 appear to belong to the .same genus. The striae are dehcate and not 

 sharp, and the minute punctiform brown markings seem to be the 

 bases of hairs, not true punctures. They may have been pigmented 

 spots, such as occur in the Erotylidae.
