the maxillary palpi is strongly securiform in both sexes of A. latipal- 

 pis, it being distinctly narrower in A. subtestacea. They have the 

 antennae very similarly formed ; this character separating them from 

 the allied A. Costce, A. maculata, &c., which have moniliform outer 

 joints. The intermediate tibiae are sinuous on their inner edge in the 

 males of both species. Schilsky's specimens were from various parts 

 of Germany. He notes that Emery had confused it with A. sub- 

 testacea. 



A. SUBTESTACEA, 8teph. 



British examples of this species are testaceous in colour, with the 

 elytra fusco-testaceous, sometimes a little darker at the apex, and the 

 abdomen usually more or less black. Mr. Saunders possesses a single 

 (?) specimen of it, from Bromley, Kent, with the base and apex of 

 the elytra, and the hind coxae, blackish. 



A. MACULATA, Fourcr. 



I have seen two females of a dark variety of this common species, 



from Ashtead and Woking, closely resembling the paler forms of A. 



Geqffroyi, but separable therefrom by the moniliform outer joints of 



the antennae. 



A. CosT^, Emery. 



The insect known in British collections under the name of A. 

 flava, Linn., var. thoracica, Linn., is reall}' the A. Gostce of Emery and 

 Schilsky, and must bear that name. Schilsky's diagnosis (Die Kafer 

 Europa's, xxxi, No. 80) fits it exactly. It is as follows : — 



A. elongata, fusca, fusco-puhescens, palpis, capite, prothorace, an- 

 tennarum hasi pedihusque testaceis, antennarum articulis 7 — 10 monili- 

 formibus {^) vel suhmoniliformibus ( ? ). Long., 2"8 — 3"6 mm. 



Mas. : anqustior, ahdominis segmento 3 medio suhproducto, laciniis 

 duahus hasi approximatis, levifer introrsum curvatis, medium segmenti 

 5' superantibus, 4° parum breviore, medio emarginato, appendicibus 

 longis, 5° apice inciso, hiloho. 



He enumerates several varieties, including one with a reddish 

 humeral spot, the latter being not uncommon in Britain. In the 

 widely distributed continental A. flava, Linn., the anterior tarsi are 

 dilated, and the abdomen is without laciniae, with the last ventral 

 segment cleft, in the male sex. In A. thoracica, Linn. (= lateralis, 

 Thorns., and confusa, Emery), the outer joints of the antennae are 

 subconic, and the abdomen in the male is furnished with laciniae. 

 Schilsky records A. Costce from France, Germany, Sweden, Austria, 

 and Italy.
