indeed, suspect to be undescribed. It is somewliat larger than j 

 impressus, with the elytra longer and more irregular, the knees pitchy 

 (the hinder femora having often a broad black band at the apex), the 

 attenniE longer, the punctuation not quite so close, and the thorax with 

 a more decided impression in the middle. 



GENicuLATUS, Oraveuhorst, Erichson. About the size of ossium. 

 Narrow, elongate ; dull black, legs rufo-testaceous, with the knees 

 pitchy-brown ; the palpi testaceous, with the apical joint more or less 

 pitchy ; and the antennse testaceous, with the first joint pitchy and 

 the club brownish. Head nearly flat, with a slender polished middle 

 line. Thorax very closely and rather strongly punctured, with a faint 

 trace of a smooth dorsal line. Elytra not longer than the thorax, 

 narrow, strongly punctured, the interstices almost rugulose. Abdomen 

 elongate, strongly and closely punctured.

 by Mr. E. Shepherd on Shirley Common, by sweeping heath at niglit.

Coremia Fcrmgata and Unidentaria. — At page 19 in the June number (just lent 

 to me) of the E/itomologist, conducted by Mr. Edward Newman, the larva of C. 

 unidentaria is described at great length, and the food-plant stated to be Oalium 

 verum and Asjperula odorata, and the egg to be laid on Galium verum. 



As far back as the year 1860, 1 began to rear the larvae of both these insects 

 from eggs obtained from captured specimens ; and I followed it up for three years 

 with always the same result, viz., Unidentaria producing invariably its hke — Ferru- 

 gata producing its like, never running the one into the other, but always remaining 

 true to the parent. 



The food-plant, however, to which they here give the preference is Gleclwma 

 hederacea, or ground-ivy, and not Galium verum, or we should not have the insecta 

 so common as they are with us, since Galium verum does not grow within 7 or 8 

 miles. The insect, confined in a box with Galium verum, is very likely to lay her 

 eggs upon that plant, but that does not prove it to be the plant upon which we are 

 to search for the eggs in the natural state. I always reared the larvae upon growing 

 plants, in pots, of ground-ivy — the food, selected by the larva itself, and I am disposed 

 to believe that to be its food par prefeo-ence. 



Both the insects are double brooded, appearing in the spring and late in the summer 

 Guonee says of Unidentaria " It is so constant that one would be tempted to 

 make it a distinct species, but that Sepp has figured it as having obtained it from 

 the same larva as Ferrugata." Sepp, very possibly, bred the two insects from larvae 

 he found, and the larvae are so similar, that I think there is scarcely any mark by 

 which they can be distinguished ; but I very much doubt that Sepp ever bred the 

 the two insects from the egg. 



If they both then produce their like, and one is still to be considered a vai-iety 

 of the other, which is the typo and which the variety ? 



In the case of A. aversata and its riband variety, I have satisfactorily proved 

 them, by breeding both from the eggs of either, to be one and the same species. I 

 cannot, however, say the same of Ferrugata and Unidentaria. — Henry D'Orville,
