378 BRITISH OlUBATIDxE. 



lanceolate heads. Interlamollar hairs shorter than 

 the pseuclo-stigmatic organs, straight, and inserted 

 very near the progaster. 



Legs of moderate length ; fourth pair slightly passing 

 the hind margin. The two front pairs are the thicker. 

 The femora of all the legs, and the coxae of the two 

 hind pairs, are flattened on the inside so as to fit 

 against the body, and bowed exteriorly. The femora 

 have chitinous ridges bordering the flattened surface, 

 both above and below, and there is a similar ridge on 

 the upper edge of the fourth coxa. All the coxse and 

 femora are rough. The tactile hairs are very long and 

 flexible on the first pair of legs, shorter but similar in 

 character on the second pair; there is also a long, 

 flexible hair on each first genual. There are a pair of 

 short curved hairs on each of the three middle joints of 

 each leg, and a few other similar hairs ; the tarsi are 

 thickly clothed with fine hairs. The claws are long 

 and thin, and their curves open. 



Abdomen shield-shaped, sharply narrowed at the 

 progaster. Lateral margins striated with fine, irre- 

 gular transverse wrinkles ; central parts of the noto- 

 gaster granulated. The cast notogastral skins arc 

 carried flat on the back and excentrically, the centre 

 of each skin being rather further back than the centre 

 of the skin that underlies it; thus each shield projects 

 a little beyond that below it at the posterior margin, 

 but the larval skin does not project beyond the first 

 nymphal. All the skins have a slightly raised or rolled 

 striated margin, and a granular, very slightly convex 

 central area, showing a few transverse folds or stria- 

 tions. The progaster is nearly straight, and bears a 

 row of short, curved hairs directed backward, except 

 the edge hair, which points outward. 



Distribution. — The species is generally distributed 

 and very common. It has been recorded in France, 

 German}'-, and Italy.
