NO. 2119. BRITISH FOSSIL INSECTS— COCKERELL. 473 



nize more than one species, and this is doubtless E. Hasina, although 

 the original figure pubhshed by Brodie shows the wing too narrow 

 apically, and omits the middle branch of the media. The radial 

 sector seems to have six branches, as in Brodie's figure, but close 

 scrutiny shows a seventh branch (with branchlets) near the apex of 

 the wing, as Handlirsch figures for E. hritannica. According to the 

 figure of E. hritannica, that also lacks the middle branch of the media. 

 E. hrodiei Handlirsch is based on the apical half of a wing, and is 

 probably identical with E. Hasina. It seems probable that the three 

 species of Elcana named from the English Lias can all be reduced to 

 one.

LOCnSTOPSIS LACOEI. new species. 



Plate 60, fig. 4. 



Anterior wing 11.25 mm. long, not quite 2 mm. broad in middle, but 

 in apical region about 2.25 mm. broad; obscurely mottled; costal 

 nervure reaching margin 7 mm. from apex of wing, and emitting 

 about seven oblique branches or cross-nervures above ; subcosta with 

 a strong obhque branch just beyond end of costal nervure, but soon 

 after closely approximated to costal margin, ending about 2.75 mm. 

 from apex of wing ; radial sector little divergent from radius, originat- 

 ing near middle of wing, and giving off three obhque branches ; media 

 also with three branches, which are simple; cubitus forked, but not 

 joining media, although a rather prominent crossvein beyond the fork 

 gives an illusory appearance of this; tln^ee anals. 



Lias at Binton (Brodie). Lacoe CoU. 3460. This is smaller than 

 the previously described species; it comes close to L. dohhertinensis 

 Handlirsch, from Mecklenburg, but is smaller and differs in the details 

 of the venation. It does not appear altogether impossible that it is 

 identical with dohhertinensis, but it is probably distinct, and Hand- 

 lirsch's species does not show some of the characteristic parts on 

 which precise identification must depend. Furthermore, our insect 

 is from the Lower Lias, the German one from the Upper Lias, and this 

 alone would be almost conclusive against specific identity. 



Holotype.—Csit. No. 61390, U.S.N.M. 



LOCUSTOPSIS BUCKLANDI (Brodie). 



Lias at Binton (Brodie). Lacoe Coll. 3461. Wing 18 mm. long, 

 very like L. Jacoei, but very much larger. The radial sector and 

 media and each three-branched, as in L. lacoei. The character of the 

 cubitus can not be made out. The costa, subcosta, and radius are 

 essentially as in L. lacoei. The insect is a true Locustopsis. Hand- 

 lirsch does not indicate the type of Locustopsis; L. elegans Handlirsch 

 is herewith designated as such.
