depredation ^s on i)oultry in Kiimey County, Tex. Early in the year 181U 

 we received s])ecinieu.s of the same creature from Mr. E. M. Ehrhorn, 

 with accompanying information concerning its habits aud its attaclis 

 on chickens aud turkeys in the neighborhood of Merced, Cal. 



Our correspondent writes that the eggs are hxid in nuisses or ckisters 

 of from 30 to 100, the larger masses being probably laid by several 

 individuals. They were found in the cracks of the walls of the chicken 

 houses aud between the cracks and boards of egg boxes. The large 

 masses are laid in layers two or three deep, the eggs composing them 

 not being flrmlj^ attached, so that they always separate when dropped 

 in alcohol. 



The eggs measure O.G to 0.8""" in diameter; are spherical aud highly 

 polished with no sculpture visible. When received they were of a 

 purplish-brown color. 



The first and second stages of this species were always found 

 attached to the chickens day and night. 



The records of this division show that this same tick was received as 

 long ago as November, 1884, from Mr. F. G. Schaupp, who reported that 

 it had recently killed large numbers of chickens in Dimmit County, 

 Tex., one farmer having lost thirty fowls from this source, lie also 

 stated that these ticks occur on trees, in cracks and under the bark, 

 and it is evident that tlie chickens which roost in the trees convey the 

 ticks from them to their coops and houses. 



Mr. Ehrhorn reports perfect success in the use of creozozoue against 

 these little pests, which are instantly killed when sprayed with it. 



SOME CHAiXGES 1^ NOMENCLATrEE. 



Since the publication of Henshaw's List of the Coleoptera of America 

 North of Mexico, ten years ago, several changes in the nomenclature 

 of certain Coleoptera of economic importance have been made, more 

 particularly among introduced or cosmoiiolitan species. The results of 

 recent studies of these forms have been made known in papers by Dr. 

 John Hamilton in Entomologica Americana (vol. vi, pp. 41-44), aud 

 in the Transactions of the American Entomological Society (vol. xti, 

 1889, vol. XXI, 1894), and by M. Fauvel in Eevenue d'Entomologie (vol. 

 Till, 1889). The changes of nomenclature in the species common to 

 Europe and North America have been adopted in the latest edition of 

 Catalogus Coleopterorum Europa*, and have 'been inserted in the 

 recently published Third Supplement to the Henshaw list. 



Tlie (lesirability of a more uniform system in our economic literature 

 is apparent, and to facilitate the adoption of the present accepted 

 nomenclature the following short list of some of the more important 

 or common species has been i)repared : 



The 15-spottecl ladybird {Anatis IJ-ptmctata 0\.)^A. ocellala Liuu. 

 riie Anstraliau ladybird ( fedalia card'nialis Mills. )=^ Xovius cardiiialis. 

 The square-necked grain beetle (Silcaiius cassiw aud 6'. quadricolUs of economic 

 literature);^ Ca//(ar;((s f/vmellatus Duv.
