 Ammophlla : — 



Ammophila Lurrii, n. sp. 



A. hirsutse simiUima, alls hyaliuis apicibus suits infuscatis, calcaribus 

 rufu-testaccis, S 2^(-'l'olo subtiis pllis tenuioribus Jimbriato, sayittarum apicibus

(J , disliiiguislied from the British form of tliat sex of Air.?«<a, Scop., by the 

 slightly clearer more hyaline wings, the less densely hairy head and thorax, the 

 black hairs of which are intermixed with white, the finer liairs on the under-side of 

 the petiole of the abdomen which do not extend under the dilated portion of the 

 segment, the red calcaria, and the much stronger claws. The genital armature 

 differs in having the sagitta; proportionately longer, more slender, and their apices 

 less dilated, and the apices of the stipites more slender and less strongly recurved 

 under the sagittte. 



'^ with clear wings, their apices with a darker band, combs of the anterior 

 tarsi quite differently formed to those of hirsufa, metatarsus with five spines instead 

 of four along its outer margin, its apex much dilated laterally on the outer side and 

 bearing two long somewhat flattened spines directed forwards, much longer than the 

 others, in hirsuta the apical dilatation bears three much shorter spines, the following 

 joints are also much more dilated laterally than in hirsuta, and each bears three 

 long flattened spines at the apex, and two ordinary ones on the side, the spines 

 much longer than the tarsal joints, propodeum more or less clothed with white hairs 

 posteriorly, petiole haired much as in the $ , calcaria red. Size about equal to that 

 of hirsuta.
