lu 1876 he broagbt out the edition of Hemiptera previously referred 

 to, vvhicli was uniform with that of the Diptera, and distributed the 50 

 copies published to very nearly the same persons and institutions to 

 which the former volumes had been sent. The lists of the recipients 

 are preserved with the copies of the two works given to the National 

 Museum. 



In all these years of publication he was adding to his plates, to the 

 text of his Coleoptera, Lepidoptera, and Diptera, and began compilations 

 of similar material from original and outside sources in other orders, 

 including the " Arachnida;, Crustacea and Annilida, Eutozoa, Helmin- 

 tha," etc. These later volumes, both " rough notes" and ''prepared 

 notes," are in the form of scrap-books, made from old public documents, 

 octavo size, and are preserved in the National Museum.* But he gave 

 up further publication, and now devoted a considerable portion of his 

 time to the reproduction, by lithographic fac-simile, of the names to ac- 

 company the entire series of plates. These slips of names were pre- 

 pared and printed for every order excepting the Lepidoptera, includ- 

 ing the work on cotton iusectsj and had his health remained unim- 

 paired he would have finished the names for the set of Lepidoptera also. 



lu 1878 he issued his last publication, if publication it can be called, 

 an edition of 12 copies of his entire set of 273 platest with a type- printed 



''In addition to his working set of plates, formerly in five quarto volumes, and his 

 published works, complete, the material deposited in the National Museum (before 

 the purchase of his plates was effected) was as follows: 



Mauuscript notes upon the Coleoptera, Lepidoptera, and Diptera, with alphabetical 

 list of plants or substances injured or destroyed, completed, and systematically ar- 

 ranged (in quarto blank-books). 



Hymenoptera, notes, etc., similar to Coleoptera and Lepidoptera, but not completely 

 arranged or systematized, "September, 1862.'" 



The same, " rough notes" and various scraps pasted into old public documents. 



Orthoptera, " prepared notes," in three volumes (old public documents). 



Hemiptera and Heteroptera, rough notes, three volumes (old public documents). 



Neuroptera " rough notes," one volume (old public document). 



Cotton insects, plates and clippings from Patent Office Agricultural Keports, and 

 some notes, in a blank scrap-book. Arachnida, etc., and Entozoa, etc., as above, 

 one volume each in old public documents. There is also one volume of original fig- 

 ures, and the volume of the complete work, uncolored, which was presented to Pro- 

 fessor Baird by the author, and a few other duplicates. 



Not having at hand the original list made by me when the transfer was eifected, with 

 Professor Baird's receipt, as the writer acted for Mr. Glover in the matter, the above 

 list was made up while examining the manuscripts in Washington recently (October, 

 1887). 



tThe complete set of illustrations comprises 273 quarto plates with 6,179 figures, 

 engraved on copper, covering the following subjects : 



Lepidoptera 

 Coleoptera .
