Tetropium castaneuin, L., and T. fuscmn, F. : supplementarii note. — Speci- 

 mens of Tetroj)ium have been found recently in several parts of England : /tt.'JCttOT 

 has been recorded from Brockenhurst by Dr. Sharp (Enfc. Mo. Mag., xxxis, p. 

 198), and from Betchworth by Mr. Saunders {loc. vit., p. 228) ; cadaneum from near 

 Leicester by Mr. Bouskell ; and an unrecorded Tetropium has been taken near 

 Esher. As remarked by Dr. Sharp {loc. cit.) the genus is more closely allied to 

 Asemum than to any other British genus, but can easily be separated by its eyes 

 being divided almost to the base, and the thorax being about as long as broad. In 

 Asemum the eyes ai-e but slightly divided, and the thorax is conspicuously broader 

 than long. The following are the principal characters given by Ganglbauer (Best. 

 Tab., vii-viii) to separate the two species : — 



Disc (as well as margins) of thorax closely punctured, dull ; basal fourth of elytra 

 covered with closer pubescence than the rest of its surface, giving the appearance 

 of a pale basal band T.fuscum, F. 



Disc of thorax scantily punctured, shiny, elytra without a pale band... 



T. castaneum, L. 



Like many of the Longicorns in this group the colour varies from black or 

 pitchy to pale brown. Mr. Atmore's specimens are typical black castaneum. Mr. 

 Saunders's black $ has the shiny thorax of castaneum and the pubescence offuscum. 

 Mulsant, Redtenbacher, and some others consider fuscum simply to be a pale closely 

 punctured var. of castaneum ; tlie last European Catalogue (1891) follows Gangl- 

 bauer.— E. A. Newbeet, 12, Churchill Road, Dartmouth Park : Jan. 23rd, 1904. 



Ceuthori'hynchus angulosus. Boh., at King's Lynn, Norfolk.- — Among the speci- 

 mens sent to me for names by Mr. E. A. Atmore (see ante) was a fine example of 

 the above rarity. — Id. 



Stenostola ferrea, Schr., and other Longicorns in the Dertvent Valley. — In the 

 summer of 1902 I met with four specimens of Stenostola ferrea, Schr., in the woods 

 bordering the river Derwent, between Rowland's Hill and Winlaton Mill. The 

 first was taken at Lockhaugh, near Rowland's Glen, on June 14th, whilst the other 

 three occurred near Winlaton Mill, two on the morning of June 21st, and the last 

 on July 17th ; all were found on coarse grass. It is interesting to note that more 

 than a month elapsed between the first and last capture. On March 3rd, 1903, I 

 took Pogonochmrus bidentatus, Thoms. {hispidus, Brit. Cat.), from under the bark of 

 a plane tree ; this, I think, the first record of this insect from our district. Clytus 

 arietis, L., is not rare in the valley, whilst two species of Rhagium — inquisitor, F., 

 and hifusciatum, i^ ., are common in all their stages, especially the former, under the 

 bark of oaks, &c. In 1902 Strangalia a>vw«<a, Herbst, and Orammoptera ruficornis, 

 F., were plentiful on Umbelliferous flowers ; and Fachyta cerambyciformis, Schr. 

 (octomaculata, F.), appeared in such numbers at Gibside and Lockhaugh that had 

 I wished I could have easily captured from two to three hundred in a couple of 

 hours, as many as sixteen having been seen congregated on one flower head ! In 

 1901 (July ?) a red variety of Toxofus meridianus, Panz., was taken at Lockhaugh, 

 whilst in the same month Qrammoptera talacieolor,'De Qt. (teyw, F.), occurred 

 occasionally at the same locality. On the lichen-covered rails dividing Ilollinside
