THE ENTOMOLOGIST 



having been beaten only once, and that from honeysuckle near 

 Gunnergate, m Cleveland. 



Conwenztia psociformis is more or less common everywhere, 

 especially on holly, ivy, and honeysuckle. 



A very brief note of the capture of this new form has 

 appeared in the * Vasculum,' the local Natural History Magazine 

 for Durham, Northumberland and the adjacent areas, but no 

 description was appended. The deficiency is now remedied. 



Cojiwentzia pmeticola (Enderlein). 



Head and thorax pitchy brown ; collar and under side of thorax 

 much paler; thorax with three white spots forming an inverted 

 isosceles triangle. Antennse 32 jointed ; legs and antennae fuscous 

 in colour. Abdomen yellowish, more or less regularly mixed with 

 brownish red. Wings, in life, snowy, but preserved in spirit, smoky, 

 clearer just above the median vein. The subcostal nerve, the radius, 

 and cubitus 1 are very dark and heavy, and the ground area near 

 them slightly darker. The other veins dark, but not black, with the 

 exception of the two outer transverse nervules which are almost 

 colourless. The neuration and depth of colouration of the wings are 

 very variable, and may be different in the two sides of the same 

 insect ; it is therefore clear that differences in neuration, such as 

 have been used to separate this species from C. psociformis, are of 

 but little use. Nevertheless the two insects cannot be confused, 

 even without the examination of the genitalia, if one considers the 

 colours of the abdomen of the two; I have never seen a G. pineticola 

 •without the reddish colouration or a C. psociformis with it.

NOTES ON NEW AND LITTLE KNOWN BEITISH 

 APHIDES. 



By Fred V. Theobald, M.A., F.E.S., &c. 



(Continued from p. 263.) 



In 1903 Clarke described a Macrosiphum valerianice in California 

 (Canad. Entom. xxxv. p. 253). I at first considered that the British 

 species was the same, but as Clarke describes the apterous viviparous 

 female as being yellow-brown and with black nectaries, and the general 

 colour of the abdomen of the alate female as yellow-brown, I have des- 

 cribed the insects I have found as a distinct species. I should not be 

 surprised, however, if they proved to be the same, a point which can 

 only be decided by a comparison of American and British specimens. 



Schoutenden (Ann. Soc. Ent. Belg. 47, p. 190, 1903) records 

 Aphis vihurni, Scopoli, from Valeriana officinalis. Tavares (Broteria, 

 S. Fiel. vi. Le Zool. p. 113) a black Aphid from Gentranthus caleitrapa, 

 Lichtenstein (Les Pucerons, p. 131) records SipJionopJiora roses, Linn., 

 and A2)his payaveris, Fabr., from Gentranthus, and the former from 

 Valeriana (p. 140). I assume these apply to the new species 

 described here and to Aphis rumicis which is common on both plants.
