Staudinger's list between the Oxyptili and Mimaseoptili ; it there follows 

 Ehrenbergianus, a doubtful European species which I have never seen. 

 Of the true MimcBseoptili, plagiodactylus is undoubtedly British, and 

 was first discovered in Wales by Mr. Greening ; the larva feeds on 

 Scabiosa columbaria. Some specimens from the Lake district have 

 seemed to me to resemble M. graphodactylus most closely.* M. Hodghin- 

 soni, discovered by Mr. Gregson, and first described in the pages of 

 this Magazine, does not resemble any European species seen by me, and 

 serotinus seems its closest ally ; its food plant is unknown to me. 

 Loewii is widely distributed, occurring in South Devon, in the eastern 

 counties, and in the Lake district ; it is, however, nowhere common. 

 The larva feeds on the seeds of the pretty Erytlircea centaurium. This, 

 with fuscus, well known to haunt Veronica chamcedrys, complete our 

 known native species of this group. They probably want more revision 

 than any other section of the plumes. 



6. Oid^matophokus (Wallengren). 



Antennae of both sexes ciliated, with the basal joint very much thickened. 

 Forehead obtuse, with the scales not forming a cone. Palpi longer than the 

 head, ascending, slender, somewhat rounded, the joints distinct, the last short, 

 blunt. The tibiae of all the legs thickened at the apex, and those of the second 

 pair even thickened in the middle. The spines of the posterior tibiae short, of the 

 first pair unequal, of the second pair almost equal. The anterior wing cleft to the 

 third part of their length, the segments somewhat slender, no posterior angle to 

 the anterior segment, that of the posterior segment not well marked. Segments of 

 the inferior wings slender, the middle segment dilated like a spoon, the fringe of the 

 posterior segment, without black scales. The anterior margin of the upper wings 

 deflexed, the posterior margin toothless, with the whole of the lower segment both 

 deflexed and turned in so as to form a channel in which the inferior wings lie when 

 the insect is at rest. Veins of the anterior wings nine in number, all simple ; the 

 1st from the base, the 2nd and 3rd from the posterior side, and the 4th from the 

 posterior angle of the cell, all running into the posterior segment, the 5th from the 

 anterior angle, and the 6th and 7th closely approximated, and the 8th all from the 

 anterior side of the cell, these run into the anterior segment, the 9th rises alone 

 from the base. The 1st, 6th, 7th, and 8th veins are very slender. The cell dis- 

 tinct, closed. The transverse veinlet very narrow, arched, with its convexity 

 turned towards the base of the wing. 



The only Swedish, and the only British, species of this genus is 

 O. lithodactylus. In Sweden, the larva feeds on Inula salicifolia ; in 

 England, on the well-known Inula conyza (or, as it is sometimes termed, 

 Gonyza squarrosa) and I. dysenterica. 



(To he concluded in our next.) 



* The larva of graphodactylus should be looked for on the seeds of Qentiance.—'R. C. R. J.
