332 [July, 



I have, as will be seen, added a new species, A. Oarneysi. Dr. 

 Power took a considerable number of specimens, and they have 

 for a long time been separated off in his collection as A. variegata, 

 but he never described them ; as, however, there is already a Mordel- 

 listena variegata, it seems best to adopt another name. 



The British species may be tabulated as follows : — 

 I. Thorax black. 



i. Elytra black, unicolorous. 



1. Antennae longer, with joints 6 — 10 increasing gradually in length, not 

 moniliform. 



A. Intermediate and posterior femora entirely, or almost entirely, 



black. 



a. Forehead, in part at least, yellow ; size larger ; apical appen- 



dages of third ventral segment in male narrow, curved 

 inwards towards apex, but not widely separated... 



A. frontalis, L. 



b. Forehead black ; * size smaller ; apical appendages of third 



ventral segment in male narrow and parallel .. 



A. pulicaria, Costa (forcipata, Muls.). 



B. Intermediate femora entirely, and posterior femora almost entirely, 



yellow ; apical appendages of third ventral segment in male 

 short and stout and strongly curved inwards, enclosing an 



almost circular space A. Oarneysi, n. sp. 



2. Antennee shorter, with joints 6 — 9 subglobose in the male and sub- 

 moniliform in the female, of about equal 6ize, scarcely as long as 

 broad or transverse. 



A. Average size larger ; last joint of antennee proportionately shorter ; 



male with two linear appendages reaching from the third to 

 the fifth ventral segment of abdomen.. A. rufilabris, Gyll. 



B. Average size smaller ; last joint of antennee proportionately longer ; 



male without appendages to the third ventral segment of 



abdomen A. melanostoma, Costa (monilicornis, Muls.). 



ii. Elytra blaok, with a bright yellow patch at each shoulder ; antennse long, not 



moniliform A. Geoffroyi, Mull. 



II. Thorax red or testaceous. 



i. Antennee longer, with the penultimate joints longer than broad, at all events 

 in the male. 



1. Elytra and head black A. ruficollis, F. 



2. Elytra and head testaceous or brownish-testaceous, the latter sometimes 



darker towards apex and base . A. subtestacea, Steph. 



ii. Antennee shorter, with the penultimate joints moniliform, transverse or sub- 

 transverse in both sexes ; head reddish-yellow or testaceous. 



1. Elytra variable in colour, blackish or brownish, but without spots... 



A.flava, L., v. thoracica, L. 



2. Elytra very light testaceous with obscure dark spots 



A. maculala, Fourc. 



A. frontalis, L. (assimilis, Snell). 

 Elongate, subfusiform, black, clothed with very fine fuscous-grey silky pu-
