68 EXPERIMENT STATION RECORD. 



Nausigaster punetulata. The author distinguishes the species from N. punctulata as 

 follows: 



(1) fa) A single spot on the wings ; 5 thoracic vittse ; from California; N. unimaeu- 

 lata n. sp. (/») Spots on wings; the spots not confluent; only 2 thoracic vittse; 

 from New Mexico; .V. punctulata, Will. 



(2) The 2 wing spots confluent, forming a more or less well-defined and extensive 

 picture, the basal cell mostly filled with the picture; 4 thoracic vittas; habitat, 

 Lowlands of Texas to Brazil; N. meridionalis, Towns. 



(3) The second basal cell almost wholly hyaline. From the Texas lowlands; X. 

 germinata n. sp. 



Five new species of Volucella are distinguished from one another and Williston's 

 ClncTophora in the same manner. Viridana n. sp., is distinguished by the occurrence 

 of a prescutal row of bristles; its bright marked, greeu scutellum and copper 

 abdomen ; Chaetophora by its hyaline wings with only a milk tinge in oblique lights; 

 Opalina n. sp., by its metallic scutellum, which resembles the abdomen in color; the 

 absence of stripes on the lace and cheeks and of yellow on the abdomen, and by its 

 wings being strongly shaded -with brown; Raphce.lana n. sp., by its striped face and 

 cheeks; Codiw n. sp., by its brown yellow scutellum, the second abdominal segment 

 resembling it and the rest of the abdomen being yellow; Nautlana u. sp., by its sec- 

 ond and third abdominal segments being of the same color as the scutellum, by a 

 nearly equal subtriangular patch on the anterior corners, and by a similar easily 

 distinguishable patch on the anterior corners of the fourth segment. 



Report of the State entomologist for 1897, \Y. M. Schoyen (Christiania, 1898, 

 pp. 45, ill. ). 



Contribution to the knowledge of some of the gall-making insects of Vallom- 

 brosa, G. Cecconi (Malpigia, 9 (1897), pp. 433-457 ). 



Ants' nests, A. Forel ( Intemat. Jour. Micron, and Nat. Sci., 3. ser., 7 (1897), No. 30, 

 pp. 347-381, pis. 2). — This is a translation of the author's -'Die Nester der Ameiseu" 

 published at Zurich in 1893, and is an interesting discussion of the various forms of 

 nests, the operation of building them, and other collateral questions such as sym- 

 biosis, the kindred relations between ants and plants, nests of mixed colonies, 

 migratory nests, road building, etc. 



On the attraction of flowers for insects, .1. LUBBOCK (Jour. Linn. Soc. Hot. Lon- 

 don, 33 (1898), No. 231, pp. 270-278). — From the results of a series of tests the author 

 maintains that both color and scent are instrumental in guiding and attracting 

 honey bees. The experiments of Plateau are said to be inconclusive, many of them 

 being conducted upon mutilated flowers with no checks. The author placed drops 

 of honey on the bright blue bracts of Eryngium amethystinum as well as on the 

 flowers, and both were visited indiscriminately. Solutions of sugar and saccharine 

 were placed near by, and the first was visited, while the other did not attract a 

 visitor. 



The San Jose scale, EL Osborn (Iowa Sta. Huh 36, pp. 860-864, figs. 3). — As this 

 insect does not occur in Iowa, this article, which is a brief popular account of it, 

 the plants that attract it, etc., is intended as a warning notice to those concerned. 



The woolly aphis of the apple, J. M. Stedman (Missouri Sta. Bpt. 1897, pp. 36-61, 

 figs. 6). — A reprint of Bulletin 35 of the station (E. S. K., 9, p. 155). 



The lesser apple leaf folder and the leaf crumpler, J. M. Stedman (Missouri 

 Sta. Bpt. 1897, pp. 62-80, figs. 6).— A reprint of Bulletin 36 of the station (E. S. R., 

 9, p. 157). 



Insect enemies of the locust, A. D. Hopkins ( West Virginia Farm Eevieto, 6 (1898), 

 No. 3, pp. 88-93, figs. 6). — The author gives a popular description of and figures 3 

 principal enemies of this tree, namely, the locust leaf beetle, locust tree borer, and 

 the carpenter worm. The unhealthy condition of the yellow and black locusts in 

 the State has within recent years attracted considerable attention. 



Termites, B. GrRASSl and A. Sandias (Quart. Jour. Micros. Sci. [London], n. ser., 40 

 (1897), J, pp. 1-75; ubs. in Jour. lioy. Micros. Soc. [London], 1S97, No. 5, pp. 370-372). —
