the author to be a new species of the genus Phleospora, and he proposes the name 

 Phleospora caraganas for it. The new species most resembles, in its external appear- 

 ance, P. o.ryacanthvR. To protect the Caragana from the fungus, the author recom- 

 mends the careful removal of the fallen leaves and the spraying of the trees in the 

 spring with Bordeaux mixture.— p. fireman. 



Basal rot in narcissus, W. Crawford {Jour. Hort., 52 [1900), No. 2691, pp. 347, 

 34s) . — A description is given of what is said to be one of the most destructive root 

 diseases of narcissus. The name basal rot has been applied to this disease and in the 

 author's opinion it is due to a species of Penicillium. The first indication of the dis- 

 ease is in the brown markings on the bulbs. These may be very slight or change 

 the whole outer appearance into a discolored mass. While the fungus is ordinarily 

 considered a saprophyte, the author believes it to be the true cause of the disease 

 and recommends for its prevention the frequent rotation of crops and the use of com- 

 mercial fertilizers. 



ENTOMOLOGY. 



Proceedings of the tv7elfth annual meeting of the Association 

 of Economic Entomologists {U. S. DejJt. Agr., D'wiswn of Ento- 

 riiolocjy Bui. 26^ n. stj'.,jj'jj. 102,2)ls. ^,fig. 1). — At this meeting, held 

 in New York City June 23, 23, 1900, the following papers were read: 



Objects of the Association of Economic Entomologists, C. P. Gillette 

 (pp. 5-15). — ^This paper is the address of the vice-president and con- 

 tains a discussion of the objects of the Association. 



The estaljlishment of a neio hcneficial insect in California, L. O. 

 Howard (pp. 16, 17). — Scutellista cyenea was brought to this country 

 from Cape Colony by C. P. Lounsbury upon twigs infested with 

 Lecaniam, olece. Previous attempts had been made in colonizing this 

 parasite (E. S. R., 10, p. 1058). 



Beneficial work of Ilyperaspis signata, L. 0. Ilotvard {])]). 17, 18). — 

 Brief notes on the agency of this insect in reducing the numbers of 

 Pidvinaria acericola (E. S. R., 12, p. 160). 



Some effects of early spring applications of insecticides on fruit trees, 

 E. P. Eelt (pp. 22-25). — Experiments were conducted in lighting the 

 San Jose scale with mixtures of kerosene and crude petroleum in water 

 in 20 and 25 per cent solutions, potash, whale-oil soap, and h3"drocyanic- 

 acid gas. The spraying was done on April 11 and the fumigation on 

 April 19-21 on a mixed orchard of 100 young pear, peach, and plum 

 trees. The results indicated that crude petroleum seriously injured 

 the trees under certain conditions. The mechanical dilutions of this 

 substance up to the strength of 25 per cent appear to be harmless if 

 applied before the buds open. 



Tile relations of Pimpla conqidsitor to ClisiocamiM americana, C. 2L 



Weed and W. M. Fiske (pp. 33, 31). — This parasite is reported as 



attacked when nearly full grown by a secondary parasite, Theronia 



fulvescens. Pinpla conquisitor occurs both as a primary and as a 



secondary parasite of the tent caterpillar. 



Observations on Diabrotica 12-p)unct(ita, A. L. Quaintance (pp. 35- 

 40). — This beetle was reported as abundant in Georgia. The lirst
