on magnolia, a Coccid allied to Dactylopiw and the common " Turtle- 

 back scale" (Lecanium hesperidum). 



During the past season, Miss Murtfeldt has noticed a harvest mite in 

 great numbers feeding upon the eggs of this species at Kirkwood, Mo. 

 From specimens sent to the Department, this mite seems to belong to 

 the genus Eupodcs and is allied to the Europeau E. hiemalis. It is very 

 minute and pale reddish-yellow in color. The body is divided into four 

 distinct segments, two of which belong properly to the abdomen, the 

 last one being the largest, the first the smallest, and the other two about 

 equal in length. The division between the last two segments is a dis- 

 tinct, whitish, transverse line, while the others are indicated by slight 

 lateral indentations and subdorsal impressions reaching to the lateral 

 margin j of the same pale color. This is probably the same mite noticed 

 by xMiss Smith, and mentioned in her report previously cited. 



Two true parasites are known to infest this scale. The first of these, 

 Coccophagus lecanii (Fitch), is very common, and ordinarily infests the 

 scales in great numbers. The adult insect is a minute, black, four-wiuged 

 fly, marked with a crescent-shaped yellow patch in the middle of the 

 body above. According to Putnam there are two broods of this para- 

 site each season, the adults appearing in May and August. The infested 

 lice become more or less inflated, finally turning black and becoming 

 rigid. The females are most commonly infested, though Putnam states 

 that he has bred the parasite from the male scale. 



The second parasite was bred by Mr. Putnam after the publication of 

 his article, and was described by Mr. Howard in his paper on the para- 

 sites of Coccids (Ann. Kept. Dept. of Agr., 188.0, p. 365) as Aphycus put- 

 vinarice. This species seems to be rare and has not been bred since. 

 It is minute, dull-yellow in color, with a dusky abdomen and with an- 

 tennas variegated with brown and white. 



REMEDIES. 



The principal remedies which have been proposed in the past are, 

 briefly, heading in the tree, i. e., cutting off the branches, and drench- 

 ing with a solution of whale-oil soap or a 1 per cent, solution of carbolic 

 acid. During the past season, however, we have recommended nothing 

 but the kerosene emulsions treated of in a previous article, and these 

 will undoubtedly give better satisfaction than anything else that can be 

 used. The best time for spraying the trees will be while the young are 

 hatching, late in May or early in June, and the apparatus described in 

 the article on the Cottonwood Beetle can be used to the same advan- 

 tage here.

ITS HISTORY. 



A worm seriously injuring the fruit of the cranberry, something as 

 the apple-worm (Garpocapsa pomonella) affects the apples, and the grape 

 fruit- worm (Lobesia botrana) grapes, has long been known to cranberry- 

 growers, but fias hitherto remained undetermined. It is referred to by
