Thorax : 2^>'onotiim somewhat yellowish-wliite, with a testaceous-brown central line, 

 slightly widest next the posterior margin ; on each side of the central line is a 

 testaceous-brown triangular spot, its apex pointing towards the anterior margin, 

 near to which are two smaU black spots. Scutellum yellowish-white, with a 

 small, black, triangular spot near each basal angle, a transverse channel not 

 reaching to the sides, which are somewhat lobate at this point, and above which 

 are two punctures, frequently black. Eli/tra very pale testaceous, semi-trans- 

 parent. Clavus — nerves white ; at the base, between the central nerve and 

 the claval suture, a short brown streak ; and along the inner margin, between 

 the nci-ves and before the apex, two short browii streaks. Coriiim- — 1st and 2nd 

 longitudinal nerves, from the base to a little beyond the 1st transverse nerve, 

 white, the remaining portion, as also those of the membrane, dark brown or 

 pieeous ; near the base, along the exterior margin of the 1st longitudinal nerve, 

 a short pieeous streak ; area enclosed by the white nerves, and base of the space 

 between the inner longitudinal nerve and suture more or less brown. Legs 

 pale yellowish ; thighs with one or sometimes two more or less distinct 

 longitudinal brownish streaks along the upper-side, towards the apex. TibicB 

 externally, at the base, with a short pieeous streak ; inner margin, next the 

 apex, more or less distinctly pieeous. Tar.si pale yellowish, 2nd joint exter- 

 nally, at the base, sometimes with a short, fine, pieeous or black line. Claws 

 black. 



Abdomen above, pitchy-brown, margins somewhat broadly pale yellowish-white ; 

 beneath pale yeUowish-white ; last genital segment and external processes pale 

 yellowish-white. Length, li line. 



This insect bears a great resemblance to tbe next species, but it 

 is more elongate, and has the two black spots on the prouotum much 

 smaller and closer together ; the (J also does not assume, as far as my 

 knowledge goes, the dark appearance, and black or nearly black legs 

 of A. venosa. 



Not uncommon, and widely distributed. It has occurred near 

 Tork, at Leo and Esher, by sweeping heath, &c., in August.

Pale testaceous ; nerves of the elytra and membrane black. 



S . Head : crown with a black central line and a round black spot on either side, 

 situated as in A. puncticejJs. Face with a central line joined to that on the 

 crown, gradually widened downwards, and terminating a little below the 

 ocelli ; adjoining each eye a short, longitudinal, black streak, its apex generally 

 joined to the extremities of the central line ; lower portion black, with a trans- 

 verse, somewhat lunate, testaceous patch in a lino with the base of the antennae.
