ON ORTSOPTERA COLLECTED BY EEV. A. E. EATON IN 

 ALGEEIA. 



BT MALCOLM BUEE, F.Z.S., P.E.S. 



I am indebted to the Rev. A. E. Eaton for a very interesting col- 

 lection of Orthoptera made by him in Algeria in 1896 — 7. 



Although the Orthoptera of this country have recently been so 

 exhaustively treated by Einot, and although the collection is not 

 large, nor absolutely representative, yet the list of the species may 

 be of interest, especially with the numerous field notes so con- 

 scientiously recorded by the collector. The number of species is not 

 great, being forty-two, and there are no novelties, but there are 

 several fine specimens of the rather rare SpJiodromerus decoloratus, 

 Ein., and Quiroguesia JBridlei, Bol. 



I have to acknowledge my gratitude to M. Einot for his invalu- 

 able assistance in determining certain species, as to the identity of 

 which I was doubtful. 



FOEFICULAEIA. 



1. Labidura riparia, (Pall.). — Observed on the sea shore at Sidi Ferruch in 



May, and at Tunis in December; nymphs plentiful on the shingle, and sametimes 



covered by the sea. 



BLATTODEA. 



HETEEOG-AMIID.ffi. 



2. Keterogamia cegyptiaca, (L.). — Occurs locally in the neighbourhood of Biskra 

 in sandy places where the subsoil is damp ; nymphs were taken on the road to 

 Tolga at the foot of the dunes, and opposite St. Germain. 



MANTODEA. 



Mantice. 



3. Mantis religiosa, L. — Common on the low lying ground at the mouth of the 

 Seybouse at Bone in September. 



4. Sphodromantis hioculata, (Burm.). — In the public gardens at Biskra in De- 

 cember. Common on Nitraria tridentata and other shrubs near the river above the 

 barrage. 



Empusid.^:. 



5. Blepharis mendica, (Fabr.). — Biskra in March ; on dry stony slopes and low 

 lying hills. The nymphs run about the ground, but the imagines resort to shrubs, 

 as Dmmia cordata, Salsola tetragona, &c., and sometimes in the early spring to the 

 leaves of Ferula vesceritensis. 



LOCUSTODEA. 

 Deoticid^. 



6. Rhacoclei.1 neglecta, (Costa). — Common on the hillsides near the suburbs of 

 B6ne in November among Ampelodesmos tenax, a coarse grass, and ChamcBrops 

 humilis — "palmetto."
