evidence that they pass the tirst stage of their development in the subuiucosa 

 of the anteriox' region of the digestive tnbe of their host. This exclusive local- 

 ization of the young larvje in the esophagus and their absence at the same time 

 from the skiu is considered sufficient proof that their entrance is only by way 

 of the digestive tract. 



Biological studies on the glossines of central Dahomey, E. Roxtbaud 

 {Compt. Rend. Acad. Sci. [Paris], 152 (1911), No. 7, pp. J,06-Ji09).—Glossina 

 palpnlis, G. lachino'ides, and (7. longipalpis are the species which the author has 

 studied. 



Experiments on transmission of bacteria by flies, with special relation to 

 an epidemic of bacillary dysentery at the Worcester State Hospital, Massa- 

 chusetts, 1910, S. T. Okton and W. L. Dodd {Boston Med. and Surg. Jour., 

 163 (1910), No. 23, pp. S63-S68, fig. i).— In investigations made during the 

 course of an epidemic of bacillary dysentery, Bacillus prodigiosus planted in 

 the hospital laundry was recovered from flies caught in traps in the scullery 

 and 5 screened ward dining rooms at an interval of from 2 to 6 days after the 

 original plant. 



In examinations made for the breeding places of the fly on the hospital 

 grounds a prolific source was found in piles of spent hops and barley malt, 

 brewery ^^aste which had been hauled in for use as a fertilizer. One oz. 

 from the richest portion of such a pile yielded 1,018 maggots. Piles of pig 

 manure mixed with straw bedding, etc., kept outside the piggery building and 

 exposed to the air and rain were also found to be badly infested. 



The role of insects as agents in the propagation of ergot of the Graminese, 

 L. Mercier (Compt. Rend. Soc. Biol. [Paris], 70 (1911), No. 8, pp. 300-302).— 

 The author finds that the conidia of ergot (Claviceps sp.) on rye grass (Lolium 

 perennc) are conveyed on the hair and in the alimentary canal of a fly (Sciara 

 thomcc). It is stated that in the vicinity of Nancy, France, where the observa- 

 tions were made, this fly is very common and is always found on L. perenne. 



Concerning the trypanosome in Myoxus nitela and the flea which appears 

 to propagate it, A. Laveean and A. Petttt (Compt. Rend. Soc. Biol. [Paris'], 

 68 (1910), No. 20, pp. 950-952).— The evidence presented indicates that Try- 

 panosoma hlancliardi which occurs in M. nitela is transmitted by means of the 

 flea described by Rothschild as CeratopJujUus larerani n. sp. 



The rat flea as the intermediate host of a rat tapeworm, W. Nicoll (Brit. 

 Med. Jour., 1911, No. 2620, p. 621).— The cysticercoid stage of Hymenolepis 

 diminuta, one of the most common tapeworms of the rat and an occasional 

 parasite of man, was found by the author in about 4 per cent of the rat fleas 

 (Ceratophyllns fasciatus) dissected. 



A single f^pecimen is usually found in each flea although 3 were found 

 in one instance. This same cysticercoid is stated to have been found by Grassi 

 and Rovelli in 4 different insects. "Only 2 instances are yet known of fleas 

 serving as the intermediate hosts of tapeworms. The first of these is the 

 well-known DipyUdium caninum. the larval stage of which is passed in the dog 

 flea and the human flea. The other has been described quite recently by Dampf 

 [E. S. R., 24 p. 758] from the flea Mesopsylla eucta, which is parasitic on the 

 jerboa (Alactaga (Dipus) jaculus)."
