f)8 Mr. F. D. Morlce on new or doubtful 



rugtcolh'sj which is very like the Algerian male in most 

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

 tion and much more flavescent wings, has also the strigosities 

 of the 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, sublseve, sparsim punctulatum. Facies 

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

 strigosus (prsecipuo in cf ), pro- et mesonotum cum mesosterno 

 transversim, scutellum postscutellumque longitudiualiter, propo- 

 deum ac pleuriB oblique (fere transversim). 



2 . Kufa sunt — caput cum antennarum dimidio basali mandibulisque 

 praeter apices nigros ; thorax pedesque, nigro parce (hi parcissime) 

 variati ; abdominis segmenta duo basalia (superne plus minusve 

 infuscata), etiam tertii basis obscure, omniumquemarginesapicales. 

 Cetera nigra vel furva, abdominis dorso nonnihil cyanescente. 



6 . Pictura minus laeta. Caput tboraxque maximam partem nigra ; 

 rufescunt tamen — antennarum scapi infra, mandibulae ut in 2 , 

 pronotum evidenter, obscure quoque latera mesonoti metapleura- 

 rumque apices, tegula) alarum, ac spiracula propodei. Abdomen 

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

 Caput tboraxque praecipue in lateribus mediocriter pallido-pilosa. 

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

 coxoeque posticae, plus miuusve albo-tomentosa vel saltem pubes- 

 centia. Ceterum corpus solita pruina vel pubescentia oruatum (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 5 brevier (nisi fallor) quam in A. Heydeni. 

 Long. 23-25 mill. 



7. Ammophila IcevicoHisj Andr^ ? 



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

 one male and two females, all at Biskra and all in May, 

 except Mr. Eaton's male (21) iii. '97, " visiting Antirrhinum 

 ramosissiinum "), which seem to agree pretty closely with 

 Andre'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.
