perhaps minor importance. The species was studied to some extent 

 in Illinois several rears ago bv Dr. S. A. Forbes, State entomologist 

 of- Illinois, and his assistants, the results obtained by him being 

 published later by Dr. Forbes under the name S plienopliorus ca-riosus 

 Oliv. Information from that source is also embodied herein. 



The author does not himself assume credit or responsibility, except 

 where indicated in the text. Where so many individual investigators 

 have contributed results of observations and studies, it becomes the 

 duty of some one to act as spokesman and put the matter in shape for 

 publication, and this duty the author has endeavored to fulfill. 



In his paper relating to this and other species of the genus Dr. 

 F. H. Chittenden, 1 of the Bureau of Entomology, came to the con- 

 clusion that S. sculptilis Horn is a synonym of S. callosus and that 

 S. sculptilis Uhler is a synonym of S. cariosus Oliv. ; also that in many 

 cases specimens received by him showed that references to either of 

 these three species related properly to S. callosus. It is upon these 

 conclusions that many of the facts herein given are based. 



HISTORY OF THE SPECIES. 



The insect was first described by Olivier in 1807, from ''Carolina," 

 as Calandra callosa. 2 This locality, now somewhat vague, will, as 

 shown in figure 17, apply almost equally well to both this species and 

 S. maidis. 



While it does not seem possible that this particular species of 

 insect could have existed all of these years in that section of the 

 country — one of the earliest settled, and therefore one of the first 

 to be brought under cultivation — without doing injury to corn and 

 rice, yet as a matter of fact over half a century did elapse before proof 

 of its ravages, accompanied by specimens of the beetles, were in the 

 possession of the Department of Agriculture. 



BUREAU NOTES. 



June 1, 1880, specimens of the beetle were received from Mr. E. T. 

 Stackhouse, of Marion, S. C, who accused them of damaging young 

 growing corn in his neighborhood. 



May 27, 1884, a report was received from Prof. J. A. Holmes, of 

 Chapel Hill, N. C, that this species was injurious to corn near Bay- 

 boro, N. C, where it is known as "kaloo bug" ; also that the belief was 

 prevalent there that the ''insect winters in the rice stubble." 



This species, specimens of which were kindly loaned Dr. Chittenden 

 for identification by Messrs. Forbes and Hart, is recorded in the pub- 

 lished notes of the State entomologist of Illinois as injuring corn at
