depredations on poultry in Kinney County, Tex. Early in the year 1894 
we received specimens of the same creature from Mr. E. M. Ehrhorn, 
with accompanying information concerning its habits and its attacks 
on chickens and turkeys in the neighborhood of Merced, Cal. 
Our correspondent writes that the eggs are laid in masses or clusters 
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 and 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 firmly attached, so that they always separate when dropped 
in alcohol. 
The eggs measure 0.6 to 0.8 mm in diameter ; are spherical and highly 
polished with no sculpture visib]e. 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. He also 
stated that these ticks occur on trees, in cracks and under the bark, 
and it is evident that the 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 creozozone against 
these little pests, which are instantly killed when sprayed with it. 
SOME CHANGES IN NOMENCLATURE. 
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 cosmopolitan 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), and 
in the Transactions of the American Entomological Society (vol. xvi, 
1889, vol. xxi, 1894), and by M. Fauvel in Eevenue d'Entomologie (vol. 
Yin, 1889). The changes of nomenclature in the species common to 
Europe and North America have been adopted in the latest edition of 
Catalogus Coleopterorum Europe, and have been inserted in the 
recently published Third Supplement to the Henshaw list. 
The desirability of a more uniform system in our economic literature 
is apparent, and to facilitate the adoption of the x^resent accepted 
nomenclature the following short list of some of the more important 
or common species has been prepared : 
The 15-spotted ladybird (Anatis 15-punctata 01.)=^- ocellata Linn. 
The Australian ladybird ( Vedalia cardinalis Muls.)= Novius cardinalis. 
The square-necked grain beetle (Silvanus cassice and S. quadricollis of economic 
literature)=Ca£/ia>'£f<s gemellatus Duv.
