HAGLOPSIS BRODIEI, new species. 

 Plate 60, fig. 7. 



Anterior wing 25 mm. long, lacking a very little of tlie extreme 

 base; width in middle 7.5 mm.; apex moderately obtuse; costa 

 straight (not convex as in Sialidas), lower margin very slightly and 

 evenly convex; longitudinal veins throughout joined by delicate 

 cross nervures, which are straight or slightly curved, vertical or more 

 or less oblique. Subcosta very delicate, its very fine terminal branch 

 ending about 10 mm. from apex of wing, where it is closely approxi- 

 mated to the first of the numerous oblique nervures which leave the 

 end of the radius to join the costa; radial sector arising (leaving 

 radius) a little more than 13.5 mm. from end of wing, and emitting 

 four branches from its lower side; media branching about 19.5 mm. 

 from apex of wing, the upper branch simple, the lower once branched, 

 the fork of the lower branch at same level as separation of jadial 

 sector; between the media and the lower margin are four simple 

 longitudinal veins, without any closed cell, the second anal curves 

 upward basally (the anal angle of the wing being rounded) and sends 

 a few very obhque nervures to the margin. 



Lias at Bin ton (Brodie). Lacoe Coll. 3453. 



Distinguished from H. parallela (Giebel) by the smaller size and 

 the simple upper branch of media. The apex is also more pointed 

 than in Brodie's figure of H. 'parallela.

HAGLOPSIS PARALLELA (Giebel). 

 Plate 60, fig. 3. 



Lias (Brodie); Lacoe Coll. 3489. A characteristic specimen, dif- 

 fering from the original figure in having the upper branch of the lower 

 division of the media forked near the end. The fork of the upper 

 division of the media is slightly over 7.5 mm. basad of the fork of the 

 lower division. The cubitus is simple, and there are three simple 

 anals. The radial sector shows four branches, instead of five as in 

 the figure, but the apex of the wing is lost. 



No. 3430, showing only the upper half of the wing, is referred to the 

 same species. In it the fork of the upper division of the media is 

 about 6.5 mm. basad of the origin of the radial sector, and the third 

 branch of the radial sector is less than half as far from the second as 

 the second is from the first. In 3489 the upper division^of the media 

 forks nearly 8.5 mm. basad of the origin of the radial sector, and the 

 thu'd branch of the sector is fuUy as remote from the second as the 

 second is from the first. However, judging by analogy with living 

 insects, these differences may well be due to individual variation 

 For convenience of reference, 3489 may be known as variety a and 

 3430 as variety b.
