white middle stripe on the pronotum and its oblong shape. This I 

 determined, by the aid of Everts' " Coleoptera Neerlandica," to be 

 C. moguntiacus, Schultze ; but as I had only a single example prudence 

 suggested an application to Mr. Champion. With his customary 

 liberality he sent for me to see the material upon which his note on 

 this species (Ent. Mo. Mag., XLIV,* p. 2) was based ; this consists of 

 five examples, two from Caterham, two from Guildford, and one ex. 

 coll. D. Sharp, all evidently of one species and the same as my own 

 specimen. The specimen ex. coll. Sharp is labelled, in a hand- 

 writing which cannot now be identified, " viridipennis, Bris. forte " ; 

 and this circumstance led to the appearance of the latter name in 

 our list. Brisout, however, distinctly says that his viridipennis is 

 distinguished from chalybseus by its adpressed pubescence. The 

 two Caterham examples have been labelled by Dr. K. Daniel " mo- 

 guntiacus, Schultze " ; but one of them already had a label placed 

 on it by Schultze himself and bearing the name " chalybasue, 

 Germ. Sch.," and therefore, since it is permissible to assume 

 that an author is more likely to know what he means by his own 

 definition than another, further inquiry became necessary. It is 

 clear, however, from a specimen labelled moguntiacus by Schultze from 

 the Konigl. Zool. Museum, Berlin, lent to me by Prof. Kolbe, as well as 

 specimens from various continental localities lent to me by Dr. Everts, 

 that our insect is the moguntiacus, Schultze, of continental authors. 

 The male of this species has the inner apical angle of the tibiae pro- 

 duced into a tooth ; there is a broad depression reaching from the 

 middle of the metasternum to the middle of the second ventral 

 segment ; in the middle of the last ventral segment there is a circular 

 depression of which the hinder edge is somewhat raised, the raised 

 portion more evident at each end than in the middle ; the last ventral 

 segment, including the concolorous depression, is extremely closely punc- 

 tured, and the preceding segment is comparatively sparingly punctured. 

 All the femora are toothed ; the tooth on the hinder pairs small but 

 evident, on the front pair very minute. The punctures on the basal 

 half of the rostrum are crowded in the male, moderately close in the 

 female. 



C. hirtulus, Germ. On June 27th, 1913, I found this species not 

 uncommon on water-cress at Colesborne ; I had previously beaten a 

 single example from Corsican pine in October.
