diventris, Mg., common throughout the summer upou burdock and other 

 plants with large leaves. 2. Dr. confusa, Stag., fenestrarum, Mg. Macq., 

 Dr.fitttebris, car b, , Fall., found mostly on newly-lopped stumps of trees, 

 less common than the former. 



Wahlberg has discovered two new genera of the Agromyzidee, in 

 Lapland. 



1. Amphipogon (Ofvers Akad. Forh. 1841, p. 217, pi. iv, f. A. ; Hornsch. 

 Arch. Scand. Beitr. iii, 446, pi. 4. A) has some affinity to Heteroneura geo- 

 myziua, Fall. ; the female resembles Scatophaga bicolor (Psila id.), but is 

 one half larger, the <$ has more the air of a Cordylura, and is distinguished 

 by a beard to the cheeks, and the like on the last segment of the abdomen, 

 which bears an appendage, and by the way in which the legs are armed and 

 clothed. A. spectrum, 2'" and upwards in length ; Lives at the foot of the 

 Lapland Alps, among damp shady beds of willows, upon fungi. 



2. Selachops (Ofvers, p. 67) with the head shaped as in Tetanops and 

 Oxyrhiua, but differing as to the insertion of the small feelers, which have 

 the awn placed nearly at the tip, and are almost imbedded in distinct 

 cavities. Sc.flavicincta, was found abundantly in June on the banks of the 

 Lulea-ELf (river). 



Loew (Eut. Zeit. 321) has characterized a new genus, Euc(elocera> which 

 is undoubtedly identical with the foregoing. The species found in May at 

 Aschersleben, E. bicolor, agrees so nearly with Sel.fiamdneta, that the chief 

 difference seems to be in the size, this being 2g'", while the Lapland insect 

 is only Is"' long. 



[Ratzeburg (Forstins. iii, 170), reared out of pupse found among the 

 woolly envelope of Chermes picese, a small fly, which he has named Leucopis 

 atratula, [but which is already described as L. obscura, Hal. (Ent. Mag. i, 

 173.)] 



Guerin (Rev. Zool. 30 ; Compt. rend, xviii, 163) has been attending to 

 the species of Chlorops injurious to grain crops. Chi. lineata, Autt., attacks 

 wheat and rye, while barley suffers from another, Chi. herpini, Guer., new 

 species. 



[According to Curtis (R. Agric. Soc. Jouru. v, 489), Chi. tceniopus is 

 destructive to the wheat and barley alike in England ; but a still more for- 

 midable enemy is a smaller fly, Oscinis vastator, given as a new species. (Ib. 

 494, pi. L, fig. 31.) 



Curtis (Gardener's Chronicle, 244) has described and figured as a new 

 species Agromyza violee, a small fly, which disfigures the flowers of the pansy 

 by numerous punctures ; but the way in which this is done is not yet clear 

 in his opinion.]
