C.fraxlni, Sign., on asli trees. 



They were on the wood of the last or previous year, never on the 

 shoot of this year's growth, and, as might have been expected at this 

 time of the year, were desiccated scales. But as both are new to our 

 record of native species it is well to note them. 



The Lecanid from oak, mentioned above, I believe, on further 

 investigation, to be Aster olecaniu7n quercicola^ Bouche, a species new 

 to our list.— J. W. D. 



ON A NEW G-ENUS ALLIED TO CORYLOPHUS. 

 BY REV. A. MATTHEWS, M.A. 



The genus Corylophus, as at present constituted, contains insects 

 of two very distinct forms ; the one represented by the typical O. 

 cassidoides, and the other by many of the species lately added to the 

 genus. In the former of these classes the antennae have only nine 

 joints, and the thorax is large, and broader than the elytra, the shoulders 

 of which are overlapped by the long and acute posterior angles of the 

 thorax ; while in the latter division the antennae have eleven distinct 

 joints, and the thorax is small, and narrower than the elytra, with its 

 posterior angles either obtuse or rectangular. 



It becomes, therefore, imperative that these groups should be 

 separated ; and since the name Corijlophus must be retained for C. 

 cassidoides and its allies, another name must be used for the remaining 

 species of the present genus. For this latter group I propose the term 

 Corylopliodes as suggestive of their previous appellation. In the fol- 

 lowing description I have merely given such superficial characters as 

 will serve to distinguish Corylopliodes from Corylophus, and have not 

 entered into any anatooiical details, although in these points, especially 

 in the organs of the mouth, the difference between the two genera is 

 even more striking than in their external characters. 



COEYLOPHODES, gCU. UOV. 



Body more or less hemispheric, generally smooth and very shining. Head small, 

 completely covered by the front of the thorax ; eyes often large and prominent ; 

 antennse generally short, eleven-jointed, very long and large, slightly recurved, 

 2nd large, but smaller than 1st, 3rd slender, shorter than 2nd, 4th — 8th very small, 

 transverse, 9th — 11th forming a much incrassated, sub-foliate club. Thorax small, 

 widest at the base, and circularly or ovally rounded in front, anterior margin more 

 or less broadly reflexed, basal margin generally sinuated with the angles not produced. 

 Scutellum generally small and rounded. Elytra large, entire, much broader than the 

 thorax. Legs generally short, tibiae sometimes flattened, tarsi four-jointed, 1st and
