The Chrysomelidae and Coccinellidse of the Philippines, J. Weise (Philip- 

 pine Jour. Sci., D. Ethnol., Anthropol., and Gen. Biol., 5 {1910), No. 4, PP- 

 223-232). — This article deals with 15 species of Chrysomelidie, 6 being described 

 as new, and 13 species of Coccinellidse, of which 5 are described as new. 



The Eutelidae of the Philippine Islands, F. Ohaus {Philippine Jour. Sci., 

 D. Ethnol., Anthropol., and Gen. Biol., 5 {1910), No. J,, pp. 232-262 ) .—Twenty- 

 two species and 1 variety are described as new to science, a total of 68 species 

 being listed as occurring in these islands. 



On some phases of parasitism displayed by insect enemies of weevils, 

 W. D, Pierce {Jour. Boon. Eat., 3 {1910), No. 6, pp. 1,51-1)58).— The author 

 presents examples of superparasitisni, as recently defined by Fiske (E. S. R., 

 23, p. 358), that have come to his attention. The various examples are clas- 

 sified in such a manner as to show the many ways in which parasites may 

 interact upon each other. 



On the life history of the alfalfa leaf -weevil, E. G. Titus {Jour. Econ. Ent., 

 3 {1910), No. 6, pp. 1(59-470). — These data are summarized in the account 

 previously noted (E. S. R., 24, p. 458). 



The color sense of the honeybee. — Can bees distinguish colors? J. H. 

 LovELL {Ainer, Nat., .'/// {1910). No. 527, pp. 673-692). — In order to determine 

 whether bees are capable of distinguishing different colors, and continuing pre- 

 vious work (E. S. R., 21. p. 763), tbe author conducted a series of experiments 

 with glass slides of different colors tbat were rendered attractive by patches of 

 honey. 



He concludes that bees easily distinguish colors whether they are artificial, 

 such as paints, dyes, etc., or natural ( " chlorophyll " ) colors. They are more 

 strongly influenced by colored slides than by those without color. Bees which 

 have been accustomed to visit a certain color tend to return to it habitually — • 

 they exhibit color fidelity. Tbis habit, however, does not become obsessional, 

 since they quickly learn not to discriminate between colors when this is for 

 their advantage. 



The parthenog'enesis of honeybees, K. W. von Dalla Torre {Zool. Zentbl., 

 17 {1910), No. 16-17, pp. 1/85-502). — The literature on the subject is reviewed 

 and a bibliograpby given. 



Notes on the nesting habits of Bembex nubilipennis, J. B. Parker {Ohio 

 Nat., 10 {1910), No. 7, pp. 163-165).— The author concludes that this wasp rears 

 but one larva at a time, although it is possible that it constructs and attends 2 

 or more burrows simultaneously. 



" The food of the larva, as shown by the nests opened, consist wholly of 

 flies, and it seems that certain females show a preference for a particular kind 

 of fly. In one nest only house flies were found ; in a second the majority were 

 stable flies ; in a third, flesh flies ; in a fourth, tachina flies. The wings, legs, 

 and usually the thorax of the fly are not consumed by the larval wasp. The 

 remains of 41 flies, of which most, perhaps all, were house flies, were taken 

 from a chamber containing an almost mature larva, and doubtless these were 

 not the total number of flies consumed by this individual." 



Ten untouched flies taken from a nest containing a half grown larva repre- 

 sented the following species: Euphorocera claripennis, Pseudopyrelia cornicina, 

 Sarcophaga assidua, and S. helicis. Although no parasites of this wasp were 

 found, in 2 instances the author discovered small larvse feeding on the flies in 

 a chamber containing an immature larval wasp. 



Scutellista cyanea, H. J. Quayle {Jour. Econ. Ent., 3 {1910), No. 6, pp. 

 Iili6-li51). — While tbis is the most important insect enemy of the black scale in 

 California, from 75 to SO per cent of the scale frequently being parasitized, the
