<^>8 Mr. F. D. .Moilce on new or douhtful 



rugicoUis, which is very like tlie Algerian male in most 

 respects, but, besides liiffering from it in a much darker colora- 

 tion and much more flavescent wings, has also the strigosities 

 of tlie mesonotum distinctly less coarse and closer, and the 

 first dorsal segment of the abdomen only a little longer than 

 the second, while it is quite twice as long in Mr. Eaton's 

 insect. Whether the two are really specifically distinct, I do 

 not venture to say without more material. At present I 

 confine myself to describing Mr. Eaton's specimens. 



Caput nonnihil incrassatum, sublaeve, sparsim punctulatum, Facies 

 ( $ ) juxta oculos margine elevate. Thorax valde rugosus vel 

 strigosus (pra)cipue in J )> pi'o- et mesonotum cum mesosterno 

 transversim, scutellum postscuteUumque longitudiualiter, propo- 

 deura ac pleurae oblique (fere transversim). 



$ . Hufa sunt — caput cum autennarum dimidio basali mandibulisque 

 praeter apices nigros ; thorax })edesque, nigro pares (hi parcissime) 

 variati ; abdominis segmenta duo basalia (superne plus minusve 

 inluscata), otiam tertii basis obscure, omuiumquemarginesapicales. 

 Cetera nigra vel furva, abdominis dorso nonnihil cyanescente. 



6 ' Pictura minus beta. Caput thoraxque maximam partem nigra ; 

 rufescunt tamen — anteunarum scapi infra, mandibulae ut in $ , 

 prouotum evident er, oljscure quoijue latera mesonoti metapleura- 

 rumque apices, tegula3 alarum, ac spiracula propodei. Abdomen 

 pedesque fere ut in $ sed nigredine magis extensa, tarsis fuscis. 

 Caput thoraxque proecipue in lateribus mediocriter pallido-pilosa. 

 Facies, tempora, humeri, insertiones alarum, metapleurarum apices, 

 coxoeque posticae, plus minusve albo-tomentosa vel saltern pubes- 

 centia. Ceterum corpus solita pruina vel pubescentia ornatum (in 

 (S ditius). Petiolus metatarso postico multo longior, Clypeus 

 baud emarginatus. Pronotum antice fortiter truncatum. Alas 

 leniter flavescentes fere hyalinae. Pedum armatura minus robusta, 

 pecten tarsalis 9 brevior (nisi fallor) quam in A. Heydeni. 

 Long. 23-25 mill. 



7. Ammophila Icevicollisj Andr^ ? 



Mr. Eaton has taken one male and one female, and I 

 one male and tw^o females, all at Biskra and all in May, 

 except Mr. Eaton's male (2!) iii. '97, " visiting Antirrliinum 

 ramosissivium "), which seem to agree pretty closely with 

 Andid's description except in some very trifling details as to 

 the colour of the abdomen. 



I am not quite certain that Mr. Eaton's (March) male, in 

 which the tarsi are nearly all quite red, whereas in all the 

 other specimens they are fuscous, belongs to the same species ; 

 but being so early a specimen, it may perhaps be immature. 

 I cannot see that structurally it differs from my own male, 

 though superficially it certainly does so.
