the occurrence of this insect in Cuba in 1871. Nevertheless, it is 

 practically certain that in 1882, at the time of the visit of Branner and 

 Koebele to Brazil, Anthonomvs grand lis did not exist as an enenry of 

 cotton in the State of Bahia or elsewhere in that country. Moreover, 

 none of the principal works dealing with the Coleoptera of that por- 

 tion of South America mentions the species. Although this by no 

 means demonstrates that Anthonomus grand is may not now be found 

 there, it certainly tends to indicate that if the species has made its way 

 into Brazil, it has, in less than twenty years, increased its range 

 remarkably. — W. D. H. 



the st. Andrew's cotton stainer. 



Mr. J. J. de Barril, the proprietor of a cotton plantation in the 

 interior of Cuba, has given us interesting details concerning Dys- 

 dercus andrese L. This species, like D. suturelhcs H.-S. of the south- 

 eastern United States, is a cotton stainer. It sometimes occurs in 

 such numbers that if cotton culture is again engaged in extensively in 

 the AVest Indies it may become considerably more important there 

 than its congener in this country, which has for many years ranked as 

 a pest of only secondary importance. 



Some } T ears ago this insect was the subject of one of Prof. T. D. A. 

 CockerelFs stylograph ic notes (Institute of Jamaica, Notes from the 

 Museum, No. 9, Feb. 2-1, 1892). The common name we have used 

 was suggested by Professor Cockerell, and is in allusion to the white 

 cross formed by the markings on the hemelytra which LinnsBus also 

 referred to in the Latin name he gave the species. In the adults this 

 coloration is quite striking. More than a century ago Sloane, a 

 traveler in Jamaica, referred to the insect as "a Cimex of a scarlet 

 colour with a white St. Andrew's cross on its back. This is one-third 

 of an inch in length. It is very often to be met with amongst 

 flowers.'* 



Our correspondent states that on his plantation, where until last 

 year no cotton had been planted for nearly half a century, the cotton 

 bolls were frequently so covered that nothing but a mass of red and 

 black insects was visible. This happened in January and February, 

 before the fruit opened, and no effect upon the plant, except that of 

 dwarfing the bolls, was observed. Toward the end of March, how- 

 ever, when all of the bolls had burst open and most of the staple had 

 been gathered, the pests fell upon what remained, and then the stain- 

 ing of the fiber became most noticeable. The color of the stain was 

 yellowish brown or ferruginous. Another observation suggests a 

 probable effective method of destroying the pests. All the hollows 

 of stumps or trees in the cotton fields were noticed to be filled by 

 millions of the immature insects. These did not eat the leaves of the 

 cotton plant, but ^ere found crawling over the grass and tobacco
