VOLUME IV. 

 Page. Line. 



7. 37. dele the second but. 

 7. last line, for forks read veins. 

 43. running title, for TKTRAGONEURA read SCIOPHILA. 

 50. G. Planetella, Wwd. ; Planetes, Wlk., may probably be reduced to 



SCIARA. 



56. 16. 24. brevipennis is a Campylomyza, according to Mr. Haliday. 

 62. 34. 5. globifera, exemplifies the g. MTCROMYIA, Rondani. 

 139. 5. The females with black thorax are referred to B, clavipes. The males of 

 both are very like each other, but there appears to be a diiference in 

 the length of the tarsi, and the diffusion of the stigmatical spot of the 

 wing. 



254. 25. for twelve read fourteen. 

 261. 29. for 12-articulatse read 14-articulatffi. 



264. 10. Stseger's description of the aquatic larva of Dixa nigra seems rather to 

 favour the affinity to the Tipulidts, but is not sufficiently explicit as to 

 some important points to justify a positive conclusion. 



269. This analytic table was drawn up without reference to two British species, the 

 introduction of which will require certain modifications of it ; and as 

 the table was previously affected by a serious misprint, it is given here 

 over again, with these corrections ; see next page. The species re- 

 ferred to are Cylindrotoma glabrata, Mg. (Zw. i. 142, vi. 274), figured 

 in Plate XXVII. fig. 8, and Limnobia occulta, Mg., for which see page 

 302, sp. 48. The latter is the type of the genus AMALOPIS, distin- 

 guished from the other groups that have been separated from Limnobia, 

 not only by the characters of venation specified in the table, but also 

 by the hairy eyes, and by the frontal tubercle, which seems to fore- 

 shadow the appearance of ocelli in that region, towards which the sub- 

 sidiary optic nerves run, in the Tipulidee, although those organs are as 

 yet undeveloped. 



315. 1. for venosa read rivosa, and dele F. 



341. 30. The trivial name fenestralis has the right of priority. Annulata, L., 

 is an error of the press in the S. N. for annotata ; see Ent. Zeitung, 

 xii. 1851, p. 135. 



R. cinctus, Fb., with which ochraceus, Ct., is identical, is considered by 

 Zetterstedt as a distinct species.
