and refklisli colouring, and from T. Lycopi by its larger size, 

 greater convexity and breadth, and by its coarsei', and, as 

 regards the elytra, very indistinctly striate punctuation. 



3. Thyarais gracilis of Kutschera, extremely like a small T. 

 ochroleiicus, in which the blackish colouring of the apical 

 half of the hind tibiae is wanting. The thorax is broader 

 than in T. ochroleucus, and more than half broader than 

 long, at the sides gently rounded, and with a gentle pro- 

 jection behind the anterior angles. This species is com- 

 mon at Mickleham and elsewhere on Senecio Jacobaea. 



4. Psylliodes Uuidipennis of Kutschera. Oblong-ovate, of 

 the size and build of P. Hyoscyami, but not so broad ; head 

 and tliorax brassy green ; elytra reddish brown, shining, 

 with brassy green legs- and testaceous antennae ; the hind 

 femora brassy, pale at the base. Its smaller size, brassy 

 colouring, and more finely and closely punctate-striate elytra 

 will serve to distinguisli it from P. chrysocephala. 



Entomological Prize Essat/s. — At the February Meeting of 

 the Entomological Society the Prize awarded by the Council 

 for an Essay " On Ailanthiculture" was presented by the 

 President to the author, Dr. Alexander Wallace ; and it was 

 announced that the Council renewed the offer of last year, 

 and would give Two Prizes, of the value of Five Guineas 

 each, to the authors of Essays or Memoirs, of sufficient merit 

 and drawn up from personal observation, on the anatomy, 

 econouiy, or habits of any insect or group of insects which is 

 in any way especially serviceable or injurious to mankind. 

 The Essays should be illustrated by figures of the insects in 

 their different states, and (if the species be noxious) must 

 show the results of actual experiments made for the prevention 

 of their attacks or the destruction of the insects themselves; 

 On some former occasions the Council has selected a definite 

 subject, as e.g., the Coccus of the Pine Apple, the larva of 

 Agrotis Segetum (the large caterpillar of the turnip), &c., but 

 on the present occasion the selection is left to the candidates 

 themselves, provided only that the subject be one fairly be- 

 longing to the Economic branch of Entomology. The Essays 

 must be sent to the Secretary at No. 1'2, Bedford How, in- 

 dorsed with mottoes, on or before the 30th November, 1866, 

 when they will be referred to a Committee to decide upon 

 their merits ; each must be accompanied by a* sealed letter
