"The adult fly deposits eggs at the edge of circular openings in sand. In 

 the areas inhabited by the flies (near Chicago) these openings ;ire usually the 

 l.-irval burrows of C. scutellaris lecontei. The sight of the burrow opening be- 

 neath the eyes appears to call forth the egg laying reflex. The larvae live as 

 ectoparasites upon the tiger beetle larv;Te for little less than one year, growing 

 slowly and molting several times. When the host is ready to pupate the larva 

 molts, moves to the abdomen, and grows to adult size in about 6 days. When 

 the pupa is fully mature it digs out by means of hooks on its head and back- 

 ward projecting bristles on the abdomen. The digging is sometimes downward 

 for a time and lasts for more than 24 hours." 



The parasite is said to be more Vindely distributed than is this beetle. 



Some earlier observations on the habits of Aphiochseta juli, F. Knab 

 (Insecutor Inscitice Menstnius, 1 (1913), No. 2, p. 24). — A brief note on the 

 parasitism of myriapods by this phorid. 



Dissemination of the leprosy bacillus by the house fly, A. Lebceuf (Bui. 

 Soc. Path. Exot., 5 {1912), No. 10, pp. S60-SG8).— The author finds that the 

 house fly can absorb enormous quantities of the leprosy bacillus through nour- 

 ishing itself on the ulcers. Leprosy bacilli can be obtained in abundance in an 

 apparently virulent condition from the dejections of infested flies. While 

 multiplication does not appear to take place in the digestive tube of Musca 

 domestica, the bacillus does not lose its vitality. Thus it appears that M. 

 domcstica may perhaps play an important role in the spread of leprosy through 

 depositing its excrements upon certain mucous membranes or abrasions of the 

 skin of healthy persons living in the immediate vicinity of leprous patients 

 with open lesions. 



Stomoxys calcitrans, Part II, C. K. Brain (Ann. Ent. Soc. Amer., 6 {1913), 

 No. 2, pp. 197-202, figs. 8). — This continuation of the paper previously noted 

 (E. S. R., 27, p. 159) deals with tlie circulatory, nervous, and reproductive sys- 

 tems, habitat, etc. 



Biological studies of the pomace fly (Drosophila ampelophila), E. Guyenot 

 {Compt. Rend. Soc. Biol. [Paris], 77, (1913). Nos. 2, pp. 97-99; 4, PP- 178-180; 

 5, PI). 223-225; 6, pp. 270-272; 7, pp. 3S2-334, flg. 1; 8, pp. 389-391; 9, pp. 

 443-445). — These several contributions take up (1) the possibility of an aseptic 

 life for the individual and her progeny; (2) the role of yeasts in alimentation; 

 (3) change of medium and adaptation; (4) nutrition of the larvse and fe- 

 cundity; (5) nutrition of the adults and fecundity; (6) resorption of spermato- 

 zoids and abortion of the eggs; and (7) the determination of oviposition. 



The mango bark borer (Ploceederus ruficornis), C. R. Jones ( Philippine Agr 

 Rev. [English Ed.], 6 {1913), No. 3, pp. 118-124, pis. 3, flg. i).— It Is stated that 

 in the vicinity of Manila many of the finest specimens of the mango have already 

 been killed and scores of others are dying from the attacks of this cerambycid 

 beetle. 



The passing of the hickory nut? H. Bird {Jour. N. Y. Ent. Soc, 21 {1913), 

 No. 2, pp. 123-126) .—The author considers it impossible to induce landowners to 

 act in unison in cutting and burning infested trees during the winter and 

 spring in order to destroy the larvae of the hickory bark borer (Scolytus quadri- 

 spinosus) as has been advocated. He thinks that saving treatment must be con- 

 fined to parks, lawns, and preserves where the owner is willing to incur some 

 expense and the management is under competent supervision. Two methods 

 of treatment are suggested, the first consisting in the use of a repellent, such 

 as whale-oil soap, at the time the beetles are ovipositing; the second that of 

 treating the holes leading to the egg cells with something that will destroy the 

 eggs and not injure the trees, such as gasoUne. The latter ia not quite the
