is i)erhaps scarcely sufficient. Wagner has since pointed out that these 

 red species possess a remarkable process on the tegmen which he calls 

 ''spornformig." This spur is a very important character, but I find 

 that it exists also in the subgenus Frotainoii of Schilsky (^flavipes, 

 dissimile, etc.). J^rotapion is perhaps the nearest ally of Hrythrapion, 

 but is no doubt sufficientlj- distinct. I therefore propose Enjtlirapion as 

 a valid genus with the following preliminary definition : — 



Ertthbapio^s- Schilsky, Kaf. Eur. xhii, 1906, p. vi. 



Color rufus. Aedeafjus tcmonihus articiclatis ; tegmine elongato^ apice hand 

 diviso, ciliatu, anterius processu lihero. Spiculum gadrale minutum. teg- 

 mentum ultimum ventrale medio profunde emarginnto. Vesica occulta. 



As regards the distinction of Apion frumentarium and cruentatum, 

 I may merely remark that the failure to distinguish them satisfactorily 

 arises from each of the two being really composite, so that a further 

 analysis is essential : —

1- — Erythrap)ion miniatum Gerraar, 



This is the largest and most beautifully coloured of our species ; the 

 sexes are very much alike. The female has the rostrum just evidently 

 longer and more slender than the male ; in the latter sex the leno-th of 

 the rostrum is about the same as from the front of the eyes to the front 

 of the thorax, in the female it is very slightly longer ; in each sex it is 

 strongly curved. The form of the head is scarcely different in the two. 

 The abdominal segments readily distinguish the two, however; the 

 terminal one is flat in the female, convex in the male, the 2nd segment 

 IS a little longer in the female and its hind margin is less perpendicular.
