Species of the Oemis Amtnopliila [Kirbj). 67 



notuin oblique, scutellura ot postsciitollum longitudinaliter, pro- 

 podeiim fere traiisversim, striato-rugosa. Antennarutn articuli 7 

 apicales infra valde turgido-dilatati, duo ultimi brevea, tcrtius 

 quarto sesqui longior. 



Biskra {Morice) Six males (v.-vi, '98). 



Tlic unusual structure of tlio antennae and broad (almost 

 fLMnalo-like) abdomen make tliis, at least in tlie male, a very- 

 distinct species. Unfortunately I did not meet with tlio other 

 sex. 



One of my specimens has the antcnuce H-jointed! (see 

 Ent. Month. Mag., Nov. 1899).

 5. Ammophihi paecilocnemis^ sp. n. 



A. Heydeni, Dhb., simillima, sed in utroque sexu tibiis posticii 

 apicem versus fortius incrassatis perquo trieatem basalem laete 

 rufis, petiole toto rufo, abdominis segmeatis apicalibus conspicue 

 viridi-cyanescentibus, cf genitaliura stipitum apidbus certe 

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

 guitur. 



Biskra (Eaton). Seven specimens {($ , 19, 20 iii., o iv. 

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



The coloration of the tibiae in this spcciea agrees with that in 

 ihen'ca as described by Andr^. The latter, however, is treated 

 by von Dalla Torre as a synonym of Ihydent, from wiiich 

 pcecilocnemis is certainly structurally distinct. Also, according 

 to Andi^, xberica 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, fifth, and sixth segments are of a beautiful 

 metallic blue without a vestige of red. 



6. Ammophila rujicollis, Lep. [■=ruhiginosa, Lap.) ? 



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

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

 female from the same place (2 v. '93) with that oi ruhiginosa. 

 The two are, 1 think, certainly the sexes of one species; and 

 M. Kobert du Buysaon tells me that rugicollis and ruhiginoai 

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

 keeps them distinct. 



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

 ]yir. Eaton's captures, because ^I. du Buysson has kindly 

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