BIBLIOGRAPHY OF ECONOMIC ENTOMOLOGY. 
39. Walsh, B. D.—Continued. 
(p. 190) in case B. [=$.] fern ora ta W alsh 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 infumata are figured. 
40. Walsh, B. D. On certain remarkable or exceptional larvae, coleoj)- 
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, Pelidnotapunctata, Cratonychus [= Me¬ 
lanotic'] incertus , and Xy lory ctes satyrus ; comparative characters of the larva 
and imago of Halisidota antiphola n. sp. [= tessellaris ] ; 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] hyalinusn. sp., and of 
larva of the last and L. ? [= Phobetron ?] tetradactylus 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- 
nus, description of the pupa; description of the larva, pupa, and imago of 
Midas fulvipes 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 
Cynipidce and a list of Cynipidce , including descriptions of sev¬ 
eral new species, inhabiting the oak-grlls of Illinois. <Proc. 
Ent. Soc. Phil., March, 1864, v. 2, pp. 443-500, fig. 
Detailed observations proving the frequent occurrence of dimorphism in the 
Cynipidce; Cynips [—Amphibolips] aciculata, a dimorphic form of C. q. 
spongifica; concludes from analogy “that aciculata $ 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 Cynipidce (Inquilince ); 
classification and characters of the same; anatomical structure and homolo¬ 
gies of the familv; 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 Ourculio. 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., No. 1, p. 28. 
Description and figures of Anthonomus quadrigibbus, a foe of the apple ; com¬ 
parison with Conotraclielus nenuphar and Anthonomus pruvicida [= Cocco-
