ALGERIA 
Asphodel, but the majority, in company with a number of males of 
A, lucens, were taken in the Foret de Chaiba at 2000 ft. elevation, 
dying near the ground about a Genista that was not in bloom. Of 
Xylocopa cyanescens, Brulle, I took but one, whereas X. violacea was 
fairly common, frequenting Asphodel among other flowers; a solitary 
Nomada agresiis, Eabr., turned up. Other bees met with were: Gera- 
tina cucurbitina, Rossi, one; Chalicodoma sicula, Rossi, one; Ghalico- 
doma (?) sp. nov ., one; Osmia Tcohlii, one <J, two ? ; 0. (?) notata , Fabr.; 
Anthidium siculum, three; Eucera trivittata, one; Eucera sp., three ; 
E. numida , Lepel., a ; Podalirius pilipes, seven at flowers of Vinca 
sp., also a variety of the male flying along the road in the Forest; 
P. dissimilis , Friese, one at flowers of Jasminum fruticans; P. 
nigroeinda , Lepel., ? var.; P. dispar , four specimens, one of them, 
at flowers of the Boraginaceous plant Solenanthus lanatus, D.C.; 
Bombus terrestris, two § visiting flowers of Solenanthus, two at 
flowers of Coronilla valentina , Linn., in the fir-wood on a dull day 
when there was little moving; Psithyrus vestalis, Lepel., a £; Apis 
mellifica ; also an unnamed bee which had five pollinia, probably of 
the Orchid Ophrys lutea, Cav., on its head. 
Flies are far more delicate in structure than Bees and Wasps, so 
that they are more difficult to preserve, moreover, they are far less well 
known, so that it is hard to get them named. Hence the following 
list does not include all the species that I brought home. The 
genus Bombylius is certainly represented by more individuals in 
Algeria than in England; of B. medius , Linn., I took three males 
and two females; I also took another species to which Mr. Verrall 
could not assign a name. Of the familiar Empis tessellata, Fabr., I 
brought home two, and a like number of another Empis not yet 
named; there are a male and a female of Lucilia sp. ; a female of 
Pollenia rudis, Fabr.; a specimen of Oligodranes (?) fumipennis, 
Loew; also two of Usia (?) atrata, Meig. 
Hammam R’ihra yielded but a solitary Dragon-fly —Orthetrum 
chrysostigma, Burm.; and only three kinds of Grasshoppers— Thai - 
pomena algeriana, Acridium aegyptiacum, and Epacromia strepens, of 
which last I got three specimens. 
My Bugs included a Centrocarenus (Centrocoris) variegatus, 
Kolen.; Gamptopus lateralis, Germ.; Carpocoris purpureopennis, De 
Geer, a fetid insect of which I took three, one of them on Asphodel; 
and several larvae of a Lygaeid, (?) Apterola pedestris, Stal, a gre¬ 
garious creature, a hundred or so being found under one stone. 
My named Beetles comprised Gopris hispanus , of which one of 
each sex came to light; Scarabaeus cicatricosus, Lucas, found on the
