vein runs almost straighl to the tip, and, commencing to branch pretty near the base, 

 semis lour widely and equally distant, superior, and almost longitudinal branches to the 

 margin, which in the miter third of the wing are considerably forked, so that the tip is 

 crowded with terminal branches. The externomedian is similarly branched, but narrowly 

 and only quite beyond the middle of the wing. Even the unusually longitudinal branches 

 of the here comparatively narrow externomedian area are forked in the apical third of 

 the wing. The anal area appears to be brief and narrow with two or three oblique veins. 

 The narrowness of the wing is its marked feature, disguising its resemblance to its allies, 

 next to which is the general multiplication of branches in the apical third of the wing. 

 It is from two and a half to three times as long as broad. 



Length of fragment, which is very nearly complete, 9 mm. ; breadth, 0.6 mm. It comes 

 from the lower Purbecks of Durdlestone Bay. Heer referred it to Blattidium.

A single specimen and its reverse on a grayish-brown stone, in which the surface, per- 

 fectly flat, is of the same color, excepting for the reddish-brown veins slightly impressed 

 on one, slightly prominent on the other, represent this species. It is but a fragment, and 

 is the only one placed here which appears to have certainly no externomedian vein ; a mere 

 fragment of the costal margin remains, but a conjectural outline is given on the plate, 

 hardly consonant with the idea that it is a hind wing; indeed the presence and character 

 of the anal vein (which is, however, no more depressed than the others) hardly allows 

 that supposition, so that it is probable that it does not belong in this group. Still the 

 neuratioii strongly reminds one of that of these species, with the single exception of the 

 arcuate anal furrow, and the absence of the externomedian vein. The mediastinal vein 

 extends beyond the limits of the fragment, but undoubtedly .stops considerably short of 

 the tip (running at first parallel to (?) and afterwards) approaching the not distant costal 

 margin, with few, distant, longitudinally oblique, nearly straight and simple branches. 

 The scapular vein runs, apparently to the tip of the wing, in a nearly straight course far 

 from the costal margin, yet commences to fork only just before the middle of the wing 

 and has only two or three superior, longitudinal, so far as can be seen simple, distant 

 branches. The median vein runs in a nearly straight course, parallel to the former, 

 through the middle of the wing, and has only a few similarly distant, longitudinally ar- 

 cuate, so far as can be seen simple veins, all, or all but one of which, arise near together 

 before the middle of the wing. The anal.furrow is broadly arcuate, terminating probably 

 a little before the middle of the wing. 



Length of fragment, 8.25 mm. ; probable length of wing, 12 mm.; its breadth. 4.25 mm. 

 It comes from the English Lias and was sent by Rev. Mr. Brodie for examination. It 

 is named after Mr. A. G. Butler, of the British Museum, who has contributed somewhat 

 to our knowledge of English fossil insects.
