barren region succeeds a hilly district, cultivated in the immediate neighbourhood of 

 the " douars," or native villages, but for the most part covered with a tliick jungle of 

 Leniiscus, dwarf oaks, argan trees {Argania sideroxylon), and the single-seeded 

 white broom (Retama rnonosperma) , replaced in the neighbourhood of the streams, 

 which have their sources in the spurs of the Atlas, by tamarisks, oleanders, and other 

 moisture-loving shrubs. I was only able to visit this fertile region on a few occasions, 

 and imder circumstances which did not admit of my devoting much attention to its 

 insect-fauna, otherwise I should have doubtless been able to bring back a far more 

 extensive collection. Notwithstanding these drawbacks, I have a goodly number of 

 specimens, including many species generally considered rare, and a few new to 

 science. A complete list of my captures would occupy undue space, and I must 

 therefore confine my observations to the most interesting species. 



Of CioindelidcB I only took Cicindela Jlexuosa, F., which occurred in profusion 

 near the sea shore, but I saw several of a large dark-coloured species. 



Among the Carabidce, my most important capture was a series of Carahus 

 stenocephalus, Faimn., allied to the far commoner C. cychrocephalus, Fairm., which 

 occurs on the more nortlierly section of the Atlantic sea-board of Morocco. My 

 specimens were mostly taken when feeding on snails {Helix erythrostoma, pisana, 

 &c.), with which the stems and branches of all the shrubs in the fertile region are 

 always covered. I took several specimens, however, on the barren sand near the 

 town. Damp spots near the aqueduct yielded two Eastern species, Metahletns 

 fuscomaculatus. Mots., and Tetrayonoderus arcuatus, Dej. ; the latter, reputed to bo 

 met with in Egypt in dry sand, occurred in considerable numbers. In similar 

 localities I took the widely distributed S/eiiolophus teutonus, Anisodadylus binotatux, 

 Calathus micropierus, Aiic/iomenus pallipes, Anchomenus marginalux, and a variety 

 of Acupalpus Liicasi, Gaub., differing from typical examples in its larger size, and 

 in the pale basal spot on the elytra not extending to the suture. By the borders of 

 the salt marsh I met witli Dyscliiriiis numidicus, Putz., Dichirotrichtis ohsolttus, 

 Dej., and one Daptux vittatus, Fisch. In the same spots, Pogomis chalceus was 

 common under dry ConfervcB, as was Pogonus Grayi, Wollast., a species also occurring 

 in saline places in the island of Lanzarote. During an excursion to a village about 

 twelve mQes from Mogador, I took several of Scariies gigas, and a couple of Platy- 

 derus tenuistriatus, WoUast., hitherto represented by the unique imperfect type in 

 the WoUastonian collection in the British Museum, captui-ed by Dr. Crotch in 

 Tcneriffe twelve years ago. Single specimens of Sphodrus Favieri, Fairm., and 

 LcBinofthenes vennstus, Clairv., occurred near the walls of the town. 



Of water-beetles I obtained but few. Pale varieties of llydroporus Ceresyi, 

 Aube, were abundant in brackish pools at the edge of the salt marsh, which localities 

 also 3'ielded Philhydrus politii.i, Kiist. (a Spanish species), llelochares lividus, Beros^us 

 qffinis, and the S. European Ochthebius pilosus, Waltl. I met -nnth a single specimen 

 of a still undetermined Sydroporus in the dry bed of a stream, the " Wad-Diarbet," 

 a few miles south of Mogador ; and Cyclonotum orbiculare was abundant at the 

 roots of Samolus I'alerandi growing in damp places near the aqueduct. 



The Brachelytra were far more abundant, but the species taken (about twenty- 

 five in numbei') were for the most part of general distribution throughout Europe 

 and the shores of the Mediterranean. I mayf however, mention Aleochara grisea,
