bluntly rounded in ? and t>l>li(|ii(>ly subtnincate in ^ ; closely, finely 

 punctate. I^egs long and slender. 



tJ. Anterior tarsi with the prolonged upper portion of joint 2 

 stout, nearly reaching the apex of 3, fringed with closely packed 

 minute black setae at the tip beneath. 



Length (excl. head) 2.^-3 mm. (c? ?.) 



Hab. Mexico (Truqui, in Mus. Brit. : (^ $), " Temisco " 

 [ ? Temascala in Pucbla] {Mus. Oxon. : $). 



One male and three females. Near A. connexus, but 

 with the exposed basal portion of the head less developed, 

 a narrower prothorax, wholly violaceous elytra, and more 

 slender darker legs; the head and femora are differently 

 coloured in the two sexes. The head in this species and 

 A. connexus is elongated much as in the N. -American genus 

 Tonaoj)s ; but the antennae in the latter are inserted much 

 nearer the eyes and at a considerable distance from the 

 anterior maigin of the head. The specimen from " Temisco" 

 in the Hope Museum at Oxford is a small female with the 

 head a little less developed than in the types. 



2. Attains connexus, n. sp. (Plate II, figs. 9, 9a, ^.) 



Moderately elongate, widened posteriorly, shining; black, the 

 clypeus, the sides of the head in front, tlie antennal joints 1-5 

 externally, the prothorax (an oval spot on the disc excepted), 

 the elytra with the outer limb, apex, and a common, transverse, 

 angulate, interrupted, median fascia, the latter extending down the 

 suture to the tip (enclosing a large, oval, subapical metallic patch 

 on the disc), the trochanters in part, tlie tibiae, tarsi, and abdomen 

 testaceous or llavo-testaceous, the rest of the elytra bluish-green; 

 sparsely clothed with short cinereous pubescence intermixed with 

 longer, erect hairs. Head elongate (the post-ocular portion greatly 

 develojicd. the eyes thus being distant from the prothorax), polished, 

 very sparsely and minutely, the base densely, punctulate, the front 

 slightly holK>wcd between the eyes ; antennae moderately long. 

 Prothorax about as long as broad, convex, minutely punctulate. 

 Elj'tra long, wider than the prothorax at the base, much widened 

 posteriorly, abruptly declivous at the apex, the apices separately 

 rounded, closely, tinely punctate. Legs rather stout, the posterior 

 tibiae feebly curved. 



(^. Anterior tarsi with the prolonged upper portion of joint 2 

 narrow, reaching the ajiox of 3. 

 Length (excl. head) 2^-3 mm.
