(1.) On the Zimb of Bruce, as connected with the Hie- 

 roglyphics of Egypt ; by the Marquis di Spineto. — Much 

 has been published, but little is known of the Zimb or 

 Tsaltsalya, which is said to spread terror and death among 

 men and beasts, wherever it is found. Its habitation is con- 

 fined to the " black fat earth," a soil in the marshy parts 

 of the Nile. Latreille supposed it to be a Tabanus, but 

 this can hardly be, if the account of its ravages is correct. 

 Other authors have supposed it to be an (Estrus, but the 

 form of its mouth seems very different. The Marquis 

 observes, that it is figured on the Egyptian antiquities, and 

 comments on the derivation of its name. He hopes to obtain 

 specimens, therefore we expect that the nature of the insect 

 will be soon satisfactorily ascertained. 



(2.) Descriptions of some hitherto Nondescript British 

 Species of May-flies of Anglers ; by John Curtis, Esq., 

 F.L.S., fyc. — This paper comprises descriptions, in English, 

 of several genera and species of the Trichoptera and the 

 Ephemeridce. The characters are short, and not very clear. 

 The new genera established are Brachycercus, Molanna, 

 Mormonia, Brachycentrus, Thya, Glossosoma, Anticyra, 

 Agapetus, and Agraylea. Many of these are indicated in 

 the second edition of Stephens's Nomenclature of British 

 Insects. 



5. Annales des Sciences Naturelles. Paris. Tome XXX. 

 — This volume contains several essays on Insects, among 

 them, — 1. "Observations on Aphides, by M. Dutrochet." 



2. " Description of some Dipterous Insects, observed in 

 Spain, by M. Leon Dufour." — Among these is Myrmemorpha, 

 a new genus, of which he found one species, a very minute 

 insect, with rudimentary wings. He considers it to be allied 

 to Scenopinus, but its habits appear to be very different, 

 and, as well as the form of its antennas, agree better with 

 those of Borborus, and of the N. G. arenaria, (Haliday). 



3. " Abstract of some Observations on the Changes of 

 Form, which the young Crustacea undergo, by M. Milne 

 Edwards." 4. " Abstract of a Monograph on the Odyneri 

 of Belgium, by M. C. Wesmael."
