74 HETEROMERA. \_AlMt8ptf. 



genus ; the antennas are filiform, or slightly moniliform towards apex, 

 with the third joint elongate ; the scutellum is triangular, and the elytra 

 finely strigose transversely; the species are found in flowers, and are 

 very variable in colour ; the appendages or " laciniae " of the third ventral 

 segment in the male present very important distinguishing characters: 



The larva of A. flava is described and figured by Ferris (Larves des Col^opteres, 

 p. 335, pi. x. f. 363) ; it is 6 mm. in length, white with the head reddish ; the head is 

 quadrate, with comparatively long antenna;, and the prothorax is also subquadratc, 

 longer than the following segments ; the last segment is long and very deeply bifid, 

 the lobes being each terminated by a hook which is long and sharp and curves back- 

 ward over the segment ; there is a small anal appendage invisible from above, which 

 serves as a proleg. 

 I Thorax black. 



i. Elytra black, unicolorous. 



1. Antennae longer, with joints 610 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 appendages 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. PTJLICAEIA, Costa. 



(forcipata, Muls.) 



B. Intermediate femora entirely, and posterior 

 femora almost entirely, yellow ; apical appen- 

 dages of third ventral segment in male short 

 and stout and strongly curved inwards, enclos- 

 ing an almost circular space A. GARNEYSI, Fowler. 



2. Antennae shorter with joints 6-9 subglobose in 

 the male and submouiliform in the female, of 

 about equal size, scarcely as long as broad or 



transverse. 



A. Average size larger ; last joint of antennae 

 proportionately shorter ; male with two linear 

 appendages reaching from the third to the fifth 



ventral segments of abdomen ...... A. BUFILABEIS, Gyll. 



B. Average size smaller ; last joint of antennae 

 proportionately longer; male without appen- 

 dages to the third ventral segment of abdomen A. MELANOSTOMA, Coxla. 



(monilicornis, Muls.) 

 ii. Elytra black, with a bright yellow patch at each 



shoulder; antennae long, not mouiliform ... A. GEOFFROYI, Midi. 

 II. Thorax red or testaceous. 



i. Antennas longer, with the penultimate joints 

 longer than broad, at all events in the male. 



1. Elytra and head black A. BUFICOI,LIS, F. 



2. Elytra and head testaceous or brownish-testa- 

 ceous, the former sometimes darker towards apex 



and base A. SUBTESTACEA, Stcph. 



ii. Antennae shorter with the penultimate joints moni- 

 liform, transverse or ^ubtransvcrse in both sexes ; 

 head red or testaceous.
