5. 12. Some female Ceratopogones have the ungues unequal. 



6. 19. for costale read costali. 



7. Analytic table. The posterior continuation of the costal vein is so faint in 



many Cecidomyzida, that they might be sought for under the preced- 

 ing embranchment. They may be distinguished from the Chironomidie 

 there, by the uniform flagellum of the antennae, the terminal joints of 

 which in the Chironomidce (one or more), tend to form a club, by their 

 disproportionate length or thickness. The veins of the wings also, in 

 the Cecidomyzidce, are usually fewer, and the membrane more hairy. 



8. Analytic table. The bifurcation of the cubital vein in the Stratiomidce is not 



universal, and this discrepancy affords a primary character for the 

 subdivision of the genera Stratiomys and Oxycera. The table is so 

 framed as to leave the genera Myopa and Zodion with the Muscidce, 

 in accordance with R. Desvoidy's arrangement (Myodaires). More lately 

 (Myopaires, 1853), he has himself abandoned this conjunction, and 

 admitted them as a distinct family, after the example of Macquart. 

 From the Muscidts they are definitely separated by the oblique direc- 

 tion of the humeral suture of the mesonotum, in this as well as in 

 general habit, agreeing with the Conopidce. Their internal anatomy is 

 equally conformable, as demonstrated by Dufour (Mem. Pres. Acad. 

 Fr. xi.), and their economy also, according to the observations of Vou 

 Ileyden, in the Isis, 1842. 



17. dele 7- connexa . . . (Not in Mr. Stephens' collection, probably not 



European.) 



21. 31. A variety, with clear yellow for the ground-colour, represents Musca hy- 

 poleon of the Liunean collection; see E. Z. xii. 1851. p. 137- 



23. 28. for Hal. MSS. read Dale, A. N. H. viii. (1841). 



24. 21. after Shr. add coccinea, Fb. ; Vill. 

 31. 26. add ccerulescens, Vill. 



42. 17- add crassicornis, \Vlbg. ; Ztt. 



77. 40. for lacch.ua read iacchus. 



83. read 1. pulicaria, Mk. m. b. 58. 14 (1796), etc. 



dele gibbosa, OL, which is probably a species of Geron. 



88. The genus Gloma has been introduced into the British lists on the autho- 



rity of Stephens' Systematic Catalogue, but in his collection it is re- 

 presented by Sciodromia immaculata. The generic name Wiedeman- 

 nia is preoccupied in botany, and both this and Heleodromia might 

 well be merged in Clinocera ; see Scholz, Schlesische Entomologische 

 Zeitung, 1850, No. 16. 

 105. 9, 10. for 1 read 2, and vice versa. 

 107. 10. for lotee read lota. 

 133. 30. add Not rare at Holywood (I.) 



136. 40. add femorata (Hemerodroniia], Heeger! Sitz. Wien. Akad. ix. (1852). 

 147. 29, and page 236, line 13,./br 1782 read 1776.
