wa8 to be found in " The Descent of Man," but since that work was written several 

 additional instances of their occurrence had been made known, showing that these 

 organs were less uniform in structure and even more wonderfully diversified in 

 position than Darwin considered them to be, while their discovery in the larvse of 

 certain forms would lead to some modification of the view that they have originated 

 in connection with sex, and primarily servo the purpose of attracting the sexes to 

 one another. He gave a detailed account of their presence on the head, prothorax, 

 mesothorax, legs, abdomen and elytra, enumerating several genera of Tenebrionidm, 

 Endomi/chidcB, HispidcB, &c., in which they had not previously been known to occur, 

 and describing those of certain Hispidm as being the most complex in structure ; 

 he mentioned additional instances in which they occur in one sex only, or differ 

 according to sex, and pointed out that, contrary to Landois' opinion, they are fre- 

 quently present in both sexes of CurcuUonidcB, but in several species the striated 

 area occupies a different position in each sex, being found on the elytra in the males 

 and on the last dorsal segment in the females. — H. RoWLAND-BROW">f and C. J.

THE COLEOPTERA AND HEMIPTERA OF THE DEAL SANDHILLS. 

 BY JAMES J. WALKER, R.N., F.L.S., &c.* ' 



The south-eastern portion of Kent, of which Dover may be re- 

 garded as the centre, has for many years held a very high position 

 in the regard of British Entomologists. Its southern situation and 

 proximity to the Continent, the beautifully diversified nature of the 

 country, and the variety of soil, elevation, and aspect to be met with 

 in a comparatively limited space, with the abundant and most varied 

 flora, have tended to make this district an almost ideal collecting 

 ground. The insect treasures of Folkestone and its famous " Warren " 

 were long ago put on record ('' The Lepidoptera of Folkestone," by 

 Dr. H. Gr. Knaggs, 1871, and Goleoptera, by the late E C. Eye, Ent. 

 Mo. Mag., vol. vi, pp. 58, et seq.) ; and the wide stretch of sandy coast 

 which extends northwards from Deal to the mouth of the IStour below 

 Sandwich, has for many years been the resort of our best collectors 

 and observers of insects, and may even now be regarded as one of the 

 most interesting and productive localities in the British Islands. There 

 is scarcely one of the insect Orders which is badly represented, the 

 dra<'-on-flies only excepted, and for bees, two-winged flies, beetles, 

 butterflies, and moths, this area has been celebrated for more than one 

 hundred years ; in spite of many obstacles to its ancient ])rimitive con- 

 dition and wealth of insect life, it is still deservedly popular. It must, 

 however, be stated that many of the rarer species of insects, more
