90 COLEOPTERA. 



94. Thyamis agilis, Rye, I.e., v, 133 (1868); ihicl, viii, 

 160. 



The capture by the Rev. H. S. Gorham and Dr. Power 

 at Bearsted, near Maidstone, in May last, of some further 

 examples of this species, has made its food-plant, Scj'opJni- 

 laria aquatica, known to us, and has also rendered an addi- 

 tion to the original description necessary. 



Two other examples, of the type form, have also been 

 taken by Mr. Gorham, during the past summer, near Staple, 

 Kent. 



The most fully coloured of these Maidstone specimens is 

 entirely black beneath, with the head; scutellum and hind 

 femora (except at the base internally) black, the suture 

 narrowly edged with black at the base and apex, and broadly in 

 the middle, and an indeterminate pitchy lateral elytra! patch. 

 This strongly marked form seems distinct from lateralis, 111. 

 (which seems confined to Vej^hascum), in the m.uch lesser 

 spurs of its posterior tibias, its less prominent humeral callus, 

 the non-disposition of its elytral punctuation in stris in the 

 upper half, its lighter coloured thorax, &c. 



95. Thyamis cerina, Foudras; Allard, I.e., 154; E. C. 

 Rye, I. c, 207. 



Rather smaller than T. hallotce, which it considerably re- 

 sembles, and from which it differs in being ferruginous-red 

 beneath, instead of black, and in having the punctuation of 

 its elytra confused (instead of being disposed in tolerably 

 distinct striae near the base), and not quite so strong. 



Taken by myself in the London district; I believe, at 

 Mickleham.
