Report of the State Entomologist. 175 



In a brief note from the same author to Entomologica Americana (i, p. 229), the idea 

 is advanced that in Cecidouiijia tubicola Osten Saclcen, the larval breast-bone is a spin- 

 ning organ, and homologous with the labium. 



Mr. D. W. Coquillett has monographed the Lomatina of North America of the Bomby- 

 lidiV; consisting of four genera, indicating one as new, and describing five new species 

 (Can. Ent, xviii, p. 81). 



COLEOPTERA.—T)r. G. H. Horn has continued to lay us under obligations for his 

 valuable contributions to Coloopterology, in descriptive, classiflcatory, bibliographical, 

 and critical papers, in the pages of the Transactions of the American Entomological 

 Society, the Canadian Entomologist, and Entomologica Americana. Their titles are 

 too numerous to permit their citation in the present paper. 



Lieut. Thorn. L. Casey has published New Genera and Species of Californian Goleoptei-a 

 (Extra Bulletin, California Academy of Science, vol. i), and a Revision of the Californian 

 Species of Lithocliaris (Bulletin No. 5, Id., vol. ii). 



Mr. Frederick Blanchard has given a careful paper On the species of Canthon and 

 Phammis of the United States, with synoptic tables of species, bibliography, and notes on 

 some other genera (Trans. Amer. Ent. Soc, xii, pp. 163-172). 



Mr. Charles W. Leng is contributing to Entomologica Americana, Synopses of Cerarn- 

 bycid(E, accompanied with illustrations (vol. i, pp. 28-35, 130-136 ; ii, pp. 27-32. 60-63 81-83, 

 102-103, 118-120, 193-200). 



Other contributions to the order, which have come under my notice, are from Messrs. 

 F. B. Caulfleld, F. Clarkson, John Hamilton, S. Henshaw, A. W. Jones, Warren Knaus, 

 C. W. Leng, A. S. Packard, E. A. Schwarz, J. B. Smith and C. W. Strumberg. 



In Entomologica Americana for July and August, 1886, is a Record of some Contribu- 

 tions to tlie Literature of North American Beetles published in 1885, by Samuel Henshaw, 

 which will be found very convenient for reference, and for which its compiler is entitled 

 to sincere thanks. 



The most generally acceptable contribution to this order made during the year, has 

 been the List of the Coleoptera of North America, North of Mexico, by Samuel Henshaw, 

 in which we are given the recent classification of Drs. LeConte and Horn, the large 

 number of new species described during the preceding twelve years, together with many 

 important synonymical corrections. Annual supplements to the List are promised 

 by the author. The labor involved in the preparation of a work of this nature is so 

 great, that each successive contribution of the kind, if as meritorious as the one under 

 notice, marks an epoch in the literature of the order. 



In the UEMIPTERA, we have had the gratification of having placed in our hands, our 

 first Check-List. It presents a classification which has been so long needed by the 

 student, of the Heteroptera. and the names of 1,118 species. A debt of gratitude is due 

 to Mr. Uhler for its preparation, in consideration of the increased facility for study 

 that it will afford, and the incentive that it will prove, to its prosecution. 



We have the promise that a similar List of the Homoptera will follow as soon as time 

 can be found for its preparation. 



The chapter on Hemiptera, in the Standard Natural History recently published by 

 S. E. Cassino & Co., of 92 pages royal octavo, is also from Mr. Uhler, and has been, I 

 believe, generally received as advancing our knowledge of an order which has been 

 much neglected in this country. 



The Fourteenth Report on the Insects of Illinois, by Prof. S. A. Forbes, State Entomo- 

 logist, treats of several Hemipterous Insects, chiefly in their economic relations. 



In the Report of the Entomologist of the U. S. Department of Agriculture for 1885, 

 Prof. Riley has presented a careful study of the two broods of the Periodical Cicada, 

 Cicada septendecim— the seventeen-year (septendecim.) and the thirteen-year race (tredecim) 

 which appeared in 1885 over a large extent of the county, and came together in southern 

 Illinois and northern Georgia. There is also a summary of distribution and future 

 appearance of all the broods (twenty-two in number) known to occur in the United 

 States ; also a recox'd of experiments made in transferring the eggs of the northern and
