HAMMAM RTHRA

road; Rhizotrogus , two of a species not in the National Collec¬ 
tion ; Tropinota hirtella , abundant on Asphodel and other flowers; 
Dasytes cyaneus, Oliv., abundant on the flowers of Centaurea pullata, 
Linn., and on the yellow flowers of a Hawkweed-like Composite; 
Drypta dentata, Rossi, one under a stone; Pachychila impressifrons, 
several under stones; P. kunzii, Sol., one under a stone on the top 
of Samsam; Aga'panthia asphodeli, Latr., a small Longicorn which 
bears a strong cryptic resemblance to the unopened buds of the 
flower from which it takes its name; it was not uncommon but 
was difficult to see, for not only were its general shape and colour 
like the buds, but its antennae closely resembled the narrow bracts 
of the inflorescence; Cantharis viridissimus, Lucas, three on the 
yellow flowers of the somewhat mustard-like Crucifer, Hirschfeldia 
geniculata , Batt.; Epilachna sp., not in the British Museum, two; 
Apion sp., one. 
At Hammam R’ihra I was greatly struck by the strangely close 
superficial resemblance between the perianth of Aristolochia longa, 
Linn., and the spathe of the Aroid, Arisarum vulgare , Targ.-Toz., a 
resemblance which I cannot attempt to explain as other than purely 
accidental. 
Attracted by the glowing accounts of the flowers of the lower 
plains we went by rail on March 27th to Affreville, but the results 
were disappointing alike as regards flora and fauna. At Bou Medfa 
station I took a new Bee, Melecta luctuosa , Scop., a female. At 
Lavaranche the widely-distributed Pyrale, S'copula ferrugalis turned 
up, and Miss Donald found an immature Mantid, Empusa fasciata , 
Brulle, on a Palmetto ( Chamaerops humilis, Linn.). At Affreville 
station I got the Grasshopper Acrotylus insubricus , Scop., and a single 
example of Synchloe daplidice. At Affreville itself the now familiar 
Euchloe belledice and E. belia were met with, as well as Chrysophanus 
phlaeas . The only other captures were the Aculeates Podalirius 
dispar , a male, and Dielis ciliata, together with the Bug Camptopm 
lateralis. 
Chiffa Gorge, Blidah, circa 1200 ft. 
April 1st, 1905. 
A visit to the celebrated Gorge was successful in so far as we 
got an excellent view of the Apes at quite close quarters. The only 
Butterflies that I actually captured were a male of Ganoris napi, the 
only one seen, and two males and one female of Thestor ballus. My 
note-book, however, tells me that in addition I saw Ganoris brassicae,
