thicker, differently-formed antennae. Differentiated from L. crassi- 

 cornis by its less robust antennae and legs, straight-sided thorax, 

 &c. ; and from L. pubescens by the truncate apex of the thorax, &c.

Group HELOPID^E .

1404. A. cheesemani, n.s. Convex, sub-oblong, not parallel, 

 attenuated posteriorly, glossy black ; antennae and palpi dark-red, 

 legs piceous, tarsi fulvous. 



Head short, immersed up to the eyes, obliquely rounded towards 

 the forehead, the latter nearly truncate, rather finely punctured, 

 more closely and coarsely near the eyes ; epistome convex, with two 

 large punctiform impressions ; labrum prominent, nearly quadrate, 

 finely punctated, ciliated. Prothorax about as long as broad, apex 

 widely incurved, base strongly emarginated, sides with distinct rims, 

 rounded anteriorly, a little narrowed yet almost straight behind the 

 middle ; hind angles nearly rectangular, not protruding, resting on 

 the elytra, the anterior rounded, moderately convex ; distinctly, but 

 not coarsely, and irregularly punctured, the punctures sometimes 

 confluent, with several larger punctures similar to those on the 

 forehead, an elongate depression near each side before the middle, 

 two others (longitudinal) near the base, aud an obsolete transversal 

 impression uniting these latter. Scutellum broad, minutely and 

 distantly punctured. Elytra elongate, oviform, widest behind the 

 middle, somewhat broader than thorax, a good deal narrowed 

 behind, distinctly marginated ; distinctly punctate-striate, some of 

 the striae irregular, the punctures not very large but close to one 

 another; interstices rather narrow, minutely and remotely punc- 

 tured. Underside shining-black, finely and distantly punctated, 

 head coarsely and rugosely. Legs punctulated ; all the tibias bear 

 fine fulvous hairs. 



Resembles A. thoracicum, but distinguished from it by the more 

 quadrate thorax, not at all sinuated towards the posterior angles. 



Length, 5 lines; breadth, 2.

1405. A. chalmeri, n.s. Elongate-oblong, narrowed medially, 

 slightly convex, nude, glossy, of a somewhat bronzed coppery (red) 

 colour, more dilute behind ; antennae reddish, legs infuscate-red, tarsi 

 rufo-testaceous. 



Head moderately coarsely but not very densely punctured, less 

 so on the vertex, epistome truncate. Prothorax rather broader than 

 long, obtusely rounded laterally, sinuously narrowed behind, posterior 

 angles rectangular and resting on the elytra, base and apex emar- 

 ginated, the latter more deeply and sinuously than the former ; with 

 a dorsal groove, two lateral foveae near the middle and two close to 

 the base, nearly a dozen large punctures, and with the surface more
