Note on Af.holuji (lli.<tfer) duodeclnistriatm, Schrk., 1781, and quatuordecim- 

 striatus, Oyll, 18f)6. — I think that these two names represent two species, 

 although this is not generally admitted, as the second name appeal's as a synonym 

 in all the more I'ecent catalogues. Stephens, in his Manual, 1839, p 149, recognised 

 them as distinct, and pointed out several distinguishing characters, and he stated 

 that both species occurred in the " London district." I have some specimens from 

 Moldavia which T think are \A-striatus, and while they are exactly similar inter se, 

 they differ from undoubted examples of l2-striatux by the more sinuous frontal stria, 

 by the narrower mandibles {V2-striatus has the mandibles somewhat canaliculate, 

 especially the one on the right side), by the punctate fovea behind the thoracic 

 anterior angle, by having a short but well marked median inner humeral stria, by 

 the dorsal strife 1—3, especially the third, being incurved near the apical margin, 

 and by the less transverse and more distinctly arched outline of the mesosternum. 

 I have not seen a British example possessing these characters, but it may be of 

 interest to those who have a native collection to examine their specimens. Some- 

 times l2-striatus has a small median inner humeral stria, more or less distinct, and 

 in the British Museum there is a single example from the Power Collection which 

 possesses it. 



Marseul, in his Monograph, 1854 (fig. 56 represents the variety of 12-striatus 

 [calling it 14^:striatus'] with the humeral striae — fig. 145 without them), and also in 

 his " Catalogue des Coleopteres d'Europe," 1863, placed the names widely apart, 

 but in the " Catalogus Coleopterorum Europae et Confinium," 1866, he inserted 

 14-striatus as a questionable variety of \2-striatus. 



Lately I have come to the conclusion that Thomson acted rightly in establishing 

 the genus Atholux, 1862, and I have assigned about forty species to it, chiefly on the 

 characters used by him. For more than forty years the genus has been disregarded ; 

 the species Thomson placed in it are, corvinus, G-erm., himaculatm, L., \2-striatus^ 

 Schr., and l^^-driatus, GylL, so it is evident that he thought the last two species 

 distinct.— Gr. Lewis, 87, Frant Road, Tunbridge Wells : October, 1906. 



Coleoptera at Woking during the past summer. — The very hot dry summer 

 seems to have suited many of the local Coleoptera of this district, several of the 

 rarer species recorded by me in past years having again put in an appearance. 

 These have chiefly been caught on the wing, just before sunset, by persistently 

 working favourable spots, and for the first time various beetles always associated 

 with Lasius fuliginosus, as Amphotis marginata and two Mgrmedonia's, have oc- 

 curred to me in this manner, away from the nests of the ants. The most important 

 capture in the district during the past summer is, of course, Lomechusa strumosa, 

 discovered by Mr. Donisthorpe on May 25th*, in the nests of Formica sanguinea, 

 while collecting in company with the Rev. F. D. Morice. The following species 

 have been taken either by my sons, while out mothing, or by myself, since May last : 

 Myrmedonia lugens, Grav., and M. laticollis, Mark., on the wing, June ; Dinarda 

 markeli, Kies., in nests of Formica riifa, Lomechusa strumosa, F., rarely, Dinarda 

 dentata, Grav., sparingly, and Quediits brevis, Er., singly, in nests of Formica 

 sanguinea, June 2nd to 14th ; the last-mentioned insect does not appear to have
