Konow distinguished another willow-feeding species, caprese, K., from lutea, 

 sajang that it differed in having the sciitellvmi deeply t\xrrowed longitiidinally 

 (^= " bitnberculate "). I have a British ? with this character, bnt I find its 

 saw, etc., absolutely identical with that of luteo • and Dr. Enslin tells me that 

 he has no belief in the distinctness of Konow's species. 



I have mentioned Konow^s identification of a British <? as fagi, Zadd., and 

 my doubts on the subject. Fagi is undoubtedly a good species, attached — as its 

 name implies — to the Beech, and there seems no reason why it shovild not occur 

 in this country as well as in Germany or Holland. If any reader of these Notes 

 has taken, or should take, a Cimbex on Beech in this country, I shoiild be truly 

 grateful to receive information of the capture. 



LoPHYRUS and Monoctenus. 



Owing to the discovery of Monoctenus in this country, my "Table 

 of Greneric Characters" (Ent. Mo. Mag., Aug. 1903, p. 189) requires 

 amendment. To the characters of Lojjhyriis should be added 

 "Humeral area (= lanceolate cell) in forewing with a cross nervure. 

 Antennae of the J' pectinated on both sides : i.e., each antenna has 

 two separate rows of branches (these rows being placed neither in the 

 same plane, nor in planes parallel to each other, but radiating apart 

 diagonally." And to this diagnosis should be opposed the follow- 

 ing : "Humeral area in forewing contracted. Antennae of (^ pec^ 

 tinated on one side only (viz., exteriorly). Monoctenus, Htg." 



Before proceeding to tabulate Lopliyms let us now finish with 

 Monoctenus. The species of it which I have here to I'ecord as British 

 i^ juniper i, L., a very singular looking little insect, especially in the ^ . 

 It is black with yellow^ tibiae and tarsi, and — in the $ —the sides of 

 the abdomen more or less rufescent. It is much smaller than anything 

 now called Lnphyrus, though it was formerly placed in that genus 

 (length about 5 mm. only, against 7 to 12 mm.). The single pecten 

 of the cJ antenna consists of about 20 branches. Near its apex the 

 antenna curls inwards ; so that the branches forming the pecten, 

 which up to this point have been parallel one to another, begin to 

 diverge in the apical direction, and look like the spokes of a wheel 

 which has lost its rim. 



I found quite a series of this insect iS' ^ and $ $ ) in the 

 Cambridge University collection lately sent to me for re-arrangement. 

 They were taken on juniper in Scotland (Nethy Bridge, &c.), June, 

 1907, by Messrs. H. Scott and C. Gr. Lamb. Many years ago Cameron 

 recorded a larva, which he found on JTiniper, but failed to rear, as 

 probably belonging to this species. The imago, however, does not
