Species of the Genus AmiijDpliila [Kirhi/). O'.l 



Tlie sjiecies conies very near IJeydeni ; hut, apart from 

 liaving the posterior i'eniorii and tihiaj h-xrgely red, tlie 

 wiiiiii^s are clearer, tlic strigai of the mesonotuin less strong 

 and tending to hecomc ohsolcte on the centre of its disk, the 

 labruni — which is usually (perhaps always?) black in lleydcni 

 — and fully half the mandibles bright red, the female tarsal 

 pccten pale and thin, and the clypeus not in the least emar- 

 ginate at the a[)cx centrally. The male genitalia seem to me 

 formed much as in lleydeni^ certainly not as in pvncilucnemis 

 described above. The apex of the abdomen has a decidedly 

 blacker tinge than in the latter species, where it is almost as 

 brightly blue as in nasuto. 



8. Ammophila alhutomentosaj sp. u. 



lUcolor, capite et tborace nigris, abdomine pedibusque m.iximam 

 partem pallide rufis. Mandibulje praetor apices iiigros, clypei 

 apex, scapus, alarum teguho cum veiiis (busalibus saltern) rufa. 

 Abdomeu segmciitis duobus basalibus pcdumque posticorura basi- 

 bus auguste iiigro-lincatis, apice in -S iinmaculato, in 2 superno 

 nigro. Caput (praetor areolam nudum extra utrumque ocellum 

 posticum bene detiuitam) thoraxque totus dense argrnteo-tomca- 

 tosa ita ut vix aut eculptura aut iutegumenti color appareut. 

 Abdomen cum pcdibus plus miuusvo cano-pruinosura, apice medio- 

 eriter pallido-piloso. Tempora albo-fimbriata. Alie fere byalinuB. 

 Antenna; tcnucs. Petiolus segniento dorsali piimo circiter quinta 

 parte longior. Clypei apex nonnibil cmargiuatus. 



Long. circ. 20 mill. 



The male and female described above have every appear- 

 ance of belonging to the same species, a very beautiful one, 

 and quite distinct from anything known to me in nature or 

 from descriptions. My specimen was taken at the foot of the 

 " ^lontagne de sable," Mr. Eaton's " on the sandhill nearest 

 the baths and tramway at llammam-es-tSalahin," i. e. prac- 

 tically on the same ground. 



The silvery clothing of the body is very thick and con- 

 spicuous, much more so than in lleydcni &c. It is inter- 

 rupted in both sexes on the vertex by an exactly similar naked 

 space adjacent on each side to the posterior pair of ocelli, so 

 definite and .symmetrical that 1 think it is probably a constant 

 character. As compared with lleydeni the present species 

 seems to be smaller and more slender, with a .slightly longer 

 petiole, thinner antenna, and clearer wings. Tiie piothorax 

 is of the usual shape; otherwise the species somewhat re- 

 sembles that next following. 



Biskia. Une male (ol v. 'l»8, Moricc)^ one female (2G iv. 

 '97, Eaton).
