72 FOSSIL INSECTS OF THE BRITISH COAL MEASURES. 



mesh work in the wide area between the inner branch of the median and the 

 cubitus. 



Affinities. — The nearest approach to a wing of this character is that of 

 Mnigmatodes danielsi, Handlirsch, in which the greater part of the outer margin 

 is also missing. The Yorkshire specimen, which may be a hind-wing, is three 

 times as long as JE. danielsi, and the veins have a stronger inward curvature. 

 In the absence of more definite details, it seems best provisionally to refer the 

 specimen to the genus Mnigmatodes. 



Genus PSEUDOFOUaiJEA, Handlirsch. 



1906. Pseudofouquea, Handlirsch, Die Fossilen Insekten, p. 125. 



Wings three times as long as wide. Cubitus with inner and outer branches. 

 Anal veins, so far as known, not united. Interstitial neuration of feeble cross- 

 nervures except between cubitus and first anal, where it is irregularly reticulate.

Type.— A broken left fore-wing, of which the two parts are preserved on 

 fragments of black shale; one fragment, bearing the basal part of the wing, in 

 the Museum of Practical Geology, Jermyn Street (no. 7272). the other, containing 

 the impression of the distal 28 nun. of the wing, in the Welsh National Museum, 

 Cardiff (no. 13,120). 



Horizon and Locality. — Lower Coal Measures (top of the Four Foot Seam); 

 Llanbradach Colliery, near Cardiff. 



Specific Characters.— Wings stout and obtusely pointed. Costa marginal and 

 flatly convex. Subcosta reaching margin in the outer third. Radius parallel with 

 subcosta, and ending in apex of wing. Radial sector diverging widely from radius, 

 and ending on the wing-apex in five divisions. Comstock regards it as a typical 

 dichotomous radial sector, with an accessory vein on tin 1 second branch ('Wings 

 of Insects,' 1918). Radius -and radial sector occupying all the wing-apex. Median 

 dichotomously branched, with an accessory vein in the fourth branch. Cubitus 

 widely divergent from median, and giving off alternate twigs from its outer and 

 inner sides, those of the inner side being much the feeblest. Anal veins four in 

 number. Interstitial neuration of feeble cross-nervures, except between the base 

 of the first anal vein and the cubitus, where it is irregularly reticulate. 



Description. — The total length of the wing is now 32 mm., ',» mm. having been
