14 BIBLIOGRAPHY OF ECONOMIC ENTOMOLOGY. 



39. WALSH, B. D. Continued. 



(p. 190) in case B. [=.] femaruta Walsh is distinct from B. [= .] femorata 

 Say ; in a note (p. 255) Ophiogomphus mainensis n. sp. is described from 

 Packard's manuscript; the venation of the Odonata and the terminal ab- 

 dominal characters of Sialis infu-nata are figured. 



40. WALSH, B. D. On certain remarkable or exceptional larvae, coleop- 



terous, lepidopterous, and dipterous, with descriptions of sev- 

 eral new genera and species, and of several species injurious to 

 vegetation, which have been already published in agricultural 

 journals. <Proc. Bost. Soc. Nat. Hist., February, 1864, v. 9, 

 pp. 286-318. 



Habits of the larva of Cotalpa lanigera, Pelidnota punctata, Cratonychus [= Me- 

 lanotus] incertus, and Xyloryctes satyrus ; comparative characters of the larva 

 and imago of Halisidota antiphola n. sp. [= lesaellaris] ; description of larva, 

 pupa, and imago of Sphingicampa (n. g.) distigma n. sp. [=bicolor~] ; char- 

 acters and affinities of Dryocampa [= Sphingicampa] bicolor f ; description of 

 imagos of Limacodes scapha and L. f [= Phobetron] hyalinus n. sp., and of 

 larva of the last and L. ? [= Phobetron?'] Mradactylus n. sp. ; description of 

 the larva, pupa, and imago of Hipparchiscus n. g. venustus n. sp. [= Aplodes 

 mimosaria]; habits and description of the larva of an undetermined Taba- 

 nua, description of the pupa ; description of the larva, pupa, and imago of 

 Midas fuhipes n. sp., habits of its larva. On pp. 309-318 descriptions of 

 several new species, with brief notes of food-habits, etc., are reprinted from 

 various agricultural journals. % 



41. WALSH, B. D. On dimorphism in the hymenopterous genus Cynips; 



with an appendix containing hints for a new classification of 

 CynipidcK and a list of Cynipldce, including descriptions of sev- 

 eral new species, inhabiting the oak-g?lls of Illinois. <Proc. 

 Ent. Soc. Phil., March, 1864, v. 2, pp. 443-500, fig. 

 Detailed observations proving the frequent occurrence of dimorphism in the 

 Cynipidae; Cynips [= Amphibolipa] aciculata, a dimorphic form of C. q. 

 spongifica; concludes from analogy "that aciculata 9 generates galls which 

 produce by parthenogenesis $ spongifica exclusively, and that $ 9 spongi- 

 fica coupling in June with these $ $ oviposit in the same month in the 

 young buds of the oak, the eggs lying dormant till the following spring, 

 when some of the eggs produce 9 spongifica in June, and some 9 aciculata 

 in the autumn or early in the following spring, which last in their turn, as 

 before mentioned, generate $ spongifica to appear in the following June;" 

 interesting details concerning the history of the group are given ; relations 

 between the true gall-flies (Psenides) and parasitic Cynipidw (Inquilina:); 

 classification and characters of the same ; anatomical structure and homolo- 

 gies of the family; the list includes fifteen (15) species inhabiting the 

 various oaks, with descriptions of their galls and of several new species; 

 seven (7) species of Inquilince are described; for the new species, see the 

 Systematic Index ; the figures illustrate the anatomy of the abdomen and 

 ovipositor. 



42. WALSH, B. D. The four-humped Curculio. A new foe of the ap- 



ple. <Valley Farmer. Keprint : <Prairie Farmer, 27 August, 

 1864, [v. 30], n. s., v. 14, p. 131, 2 figs. S.-b., Xo. 1, p. 28. 



Description and figures of Anihouomus quadrigibbus, a foe of the apple; com- 

 parison with Conotrachclns nenuphar and Anthonomus pruricida [=(70cc0-
