Species of the Genus Ammoplilla (Kirby). 67 



notum oblique, scutellum et postscutellum longitudinaliter, pro- 

 podeum fere transversim, striato-rugosa. Antenuarum articuli 7 

 apicales infra valde turgido-dilatati, duo ultinii breves, tertius 

 quarto sesqui longior. 



Biskra {}forice). Six males (v.-vi. '98). 



The unusual structure of the antennae and broad (almost 

 female-like) abdomen make this, at least in the male, a verj 

 distinct species. Untbrtunately I did not meet with the other 

 sex. 



One of mj specimens has the antenuaj It-jointed! (see 

 Ent. Mouth. Mag., Nov. 1899). 



Group A.MMOPHILA (sensu stricto). 



5. Ammophila poecilocneniis, sp. n. 



A. Hei/deni, Dhb., simillima, sed in utroque sexu tibiis posticis 

 apicein versus fortius incrassatis perquo trientem basalem \xte 

 rufis, petiole toto rufo, abdominis seginentis apiealibus conspicue 

 viridi-cyanescentibus, c? genitaliuin stipituni apicibus certe 

 latioribus, $ pectine (ut videtur) minus robusto, facile distin- 

 guitur. 



Biskra (Eaton). Seven specimens ((^, 19, 20 iii., 5 iv. 

 '95 ; 22, 25 iy. '97 : ? , 29 iii., 3 iv., '97). 



The coloration of the tibitein this species agrees with that im 

 therica as described by Andre. The latter, iiowever, is treated 

 by von Dalla Torre as a synonym of Heydeni^ from which 

 pcecilocnemis is certainly structurally distinct. Also, according 

 to Andr^, iberica has the petiole black, and of the following 

 segments only the fifth above and the sixth entirely are 

 black, whereas in all the specimens before me the petiole is 

 red, and the fourth, fifih, and sixth segments are of a beautiful 

 metallic blue without a vestige of red. 



6. Ammophila rugicollis, Lep. [■=ruhiginosaj Lep.) ? 



A male taken by Mr. Eaton at Biskra (3 v. '97) seems to 

 agree well with Lepelletier's description of rugicollis, and a 

 female from the same place (2 v. '93) with that of rubiginosa. 

 The two are, I think, certainly the sexes of one species; and 

 M. Robert du Buysson tells me that rugicollis and rubiginosa 

 are synonyms, though I see that v. Dalla Torre's catalogue 

 keeps tliem distinct. 



1 am in some doubt, however, as to the determination of 

 Mr. Eaton's captures, because M. du Buysson has kindly 

 sent me a male from Taraatave of what he considers to be
