from his state and a score or more new to his own collection, even 

 though he has been a Hfe-long student. But for definitive results 

 this pile should in each case be watched for a full calendar year. 

 Watchfulness should be relaxed only when the ground is actually 

 frozen hard. 



The study of distribution is now becoming of paramount im- 

 portance in these days of state and local hsts. What would be 

 the benefit to science, if fifty observers adopted this search and 

 submitted their records to some leading coleopterist for a sym- 

 posium? There are plenty of masters who will undertake the 

 identification of doubtful species. A complete Hst would tell 

 more about distribution than any other project ever undertaken. 



About twenty such grass piles have already been started. If 

 interested or desiring additional information, please write to the 

 editor of the Bulletin. 



A NEW SPECIES OF RHEUMATOBATES BERGR. (HEM., 



GERRID^). 



By E. Bergroth. 



In my revision of this remarkable genus* four species were 

 described, two of which were known from the Atlantic coast 

 region of the U. S. (New York State to District of Columbia), 

 one from the island of Grenada (Lesser Antilles), and one (a 

 new species) from the Caribbean coast of Guatemala. Thus no 

 species had been found far from the sea, but since that timic Mr. 

 W. J. Gerhard, of Chicago, has sent me specimens of Rh. Rileyi 

 Bergr. taken by him in Palos Park, Illinois. I think the want of 

 further records of the genus from the interior parts of the United 

 States is merely due to the fact that very few American entomol- 

 ogists (like those of Europe, alas !) taken an interest in the insects 

 of this order. My friend de la Torre Bueno has submitted to 

 my examination numerous specimens of a Rheumatohates which 

 proves to be undescribed, and as the descriptions in my revision 

 are detailed, and specimens of the two other North American
