ECONOMIC ZOOLOGY — ENTOMOLOGY. 259 



This attention is due to the excretion by the larva, from a slit on the tenth body 

 segment, of a liquid agreeable to the ants. 



Third report of director of fruit fly control, W. M. Giffard (Hawaii. For- 

 ester and Agr., 9 (1912), No. 2, pp. Ji6--'i8).— It is stated that since the last 

 report (E. S. R., 26, p. 758) the entomological department has succeeded in 

 breeding the Mediterranean fruit fly from the fruit of carambola and brown 

 persimmon. " In the latter case a single fruit was handed us, it having been 

 the only one maturing on a newly introduced species." The author states that 

 this fly has been bred from Chinese oranges, received from the Kohala district 

 in the island of Hawaii. 



On the rearing" of a Dermatobia hominis, A. Busck (Proc. Ent. 8oc. Wash., 

 14 {191,1), No. 1, pp. 9-13). — An account of the actual breeding of this oestrid 

 parasite from man. 



The infestation took place at Cabima, Panama, on May 29; only 1 cast skin 

 was observed during the larval period; this was shed and pushed out nearly 

 entire through the aperture in the skin on July 19 ; on September 9 the larva had 

 attained full growth and left the arm, posterior end first. On being placed in 

 a jar with wet sand it immediately burrowal down 2 in. to the bottom of the 

 jar and pupated. The fly issued on October 23. The author states that a much 

 greater period of sleep was necessary during infestation. 



The horse botflies in Argentina, F. Lahille (/Jo?. Min. Agr. [Buenos Aires'i, 



13 {1911). No. 12, pp. 836-85G, pi. 1, figs. 8; Rev. Asoe. Rural Uruguay, J,t 

 (1912), No. 2, pp. 136-145). — An account of the life history, habits, and occur- 

 rence of Oastrophilus nasalis, the effect of its presence upon the host, prophy- 

 lactic measures, etc., with notes on several other species. 



The genera Hypera and Phytonomus (Coleoptera, Family Curculionidae) 

 in America, north of Mexico, E. G. Titus {Ann. Ent. 80c. Amer., If {1911), No. 

 Ii. pp. 3S3-.'il3, pis. 10, figs. 12). — One species of Hypera {H. punctata) and 12 

 of Phytonomus, namely. P. eximius, P. quadricollis, P. com plus, P. diversipimcta- 

 tus, P. seriatus, P. trimttatus, P. maritimus, P. castor, P. puhicollis, P. meles, 

 P. nigrirostris, and P. posticus are recognized. Under each species the author 

 gives a complete synonymic bibliography, original description, new descriptions 

 of the stages so far as known, distribution, food plants, and life history. Maps 

 illustrating the distribution are included. 



A revision of the genus Lasconotus, E. J. Kraus (Proc. Ent. Soc. Wash., 



14 {1912), No. 1, pp. 25-44)- — The author recognizes 24 species as belonging to 

 this genus of the coleopterous family Colydiidse, 9 of which are described as 

 new to science. 



" Very little is known concerning the exact habits of the species. They are 

 usually found associated with various scolytids inhabiting coniferous trees. 

 Principal among these are Pityophthorus (Tomicus), and at least 2 species are 

 found with Phloeosinus. Whether tliey are commensals or predaceous is not 

 well known. The mouthparts, so far as I have examined, would indicate a 

 predaceous habit, but even if so, whether they prey upon the scolytids them- 

 selves or the numerous other insects found in their galleries is still an open 

 question. The larva is also so far unknown." 



The sugar cane beetle in Mauritius {Agr. News [Barhadosl, 11 (1912), 

 No. 258, p. 90). — It is stated that the beetle, which has recently become a se- 

 rious enemy of sugar cane in Mauritius," has been identified as Phytalus 

 smitlii. The fact that this species occurs in the Barbados, but is not of eco- 

 nomic importance, is thought to be due to some very effective natural enemy.

 Northwest, J. A. Hyslop (U. 8. Dcpt. Agr., Bur. Ent. Bui. 95. pt. 5, pp. 13-87,
