Art. XXXIV. — Notice of Entomological Works. 



1. British Entomology, hyJ. Curtis, F.L.S,, Nos. 105— 1 10. 

 — No. 105 contains, 1. Oxyporus maxillosus. This is a beautiful 

 figure ; the species from which it is drawn is very rare as 

 British, existing only in the cabinets of the British Museum 

 and Mr. Kirby ; its congener rufus is comparatively common, 

 being taken at Birchwood and other localities near London, in 

 an agaricus, which grows on the stumps of fir-trees which 

 have been felled. 2. Nomada Dalii, with a list of thirty-seven 

 British species : the economy of this tribe of bees is at present 

 unknown, although some of the species are among our com- 

 monest insects. 3. Cerostoma annulatella. This elegant little 

 moth is remarkable for holding its antennas, when at rest, 

 porrected in a right line from its head, and touching each other, 

 in the manner of Phryganece. 4. Hijjpobosca equina. This 

 insect is much too highly coloured ; we have often possessed 

 them when alive and active; they are nearly unicolorous. The 

 Hippohoscce ai'e pupiparous, and, with the Notostomata of 

 Dr. Leach, probably form an osculant group, which connect 

 the Diptera in Insecta with some of the parasitical Acaridca. 

 The tenacity of life in these horse-flies is truly remarkable ; we 

 have deprived them of their heads, and allowed them to run 

 again on our horse, which they do backwards, forwards, and 

 sideways, with precisely the same apparent ease as before : 

 although they do not bite, the irritation they occasion appears 

 to be intense, and renders horses that are unaccustomed to them 

 perfectly unmanageable. — No. 106 contains, 1. Areopagus 

 puncticollis. This curious little insect had been previously 

 very correctly figured by Mr. Denny, in his excellent mono- 

 graph on the Pselaphidce, and we rather regret Mr. Curtis 

 did not wait for a new species before he figured the genus. 

 2. Fcemis assectator. 3. The beautiful and rare moth, Psodos 

 equestrata. 4. Xylota bifasciata, one of the Syrphidce.
