FOSSIL INSECTS OF THE BRITISH COAL MKASrUKS 



The wing-fragment must lie referred to this provisional order in the absence of 

 knowledge of the whole wing-structure. The much-divided median vein is more 

 comparable with that of Gennn:in-(i iri/xnuL Matthew, than with that of Mixotermes 

 liigaitensis, Sterzel, and is also correlated with a shorter subcostal vein, although in 

 IT. irllxiuil that vein extends beyond the point at which the radial sector arises from 

 the radius. An open series of cross-nervures is present in both genera, as in this 

 specimen, and both have the same well-rounded apex. The wing-fragment is 

 suggestive of llfiiii'i-ixfitt orrii/fi/tnlix, Dana, but has a less branched radial sector. 

 I provisionally refer it to Geroiieura with the specific name of urnln.

Head large, with strong mouth-parts, and bearing long slender antenna 1 ; 

 prothorax large and elongated, and the body strongly built. Legs either uniform 

 in character and fitted for running, or the hind-legs modified for leaping. Wings 

 more specialised than those of the Palaeodictyoptera, and capable of folding on the 

 abdomen when at rest, with the enlarged anal areas of the hind-wings doubled 

 under, owing to the formation of a fold between the anal area and the rest of the 

 wing. The principal veins and their subdivisions not so strongly curved inwardly 

 as in the Palseodictyoptera. 



I landlirsch established this order to include a series of insects intermediate in 

 character between true Orthoptera and I'aheodictyoptera, to which Scudder had 

 previously given the name of Palaeodictyoptera Neuropteroidea.

(! i' in 1 i-'n- Clnii-iirfi'i-K. Large wings two-and-a-half times as long as wide; inner 

 margin more convex than miter margin, and curving distallv into the latter. 

 Principal veins broad and Hat in the basal third, and diminishing in si/,e distallv. 

 Sulicosta and radius reaching the wing-apex. Median vein with two mam 

 branches, (lie outer with most subdivisions. Cultit us with two main branches, each 

 much subdivided. Anal veins numerous. Interstitial neuratioii of irregular 

 nervures, and a loose meshwork in the wider areas.
