elytra elongate, narrowed posteriorly, with a feeble depression 

 below the base, the punctuation a little larger than that of the 

 thorax and arranged in irregular closely approached rows which 

 become nearly indistinct at the apex, tlie interstices not raised or 

 convex ; legs short and stout, the tibias at the apex and the first 

 joint of the anterior tarsi strongly dilated in the male, fulvous. 

 In the female the shoulders are raised into an acute costa which 

 gradually is broken up into small tubercles, this is followed by 

 another longer costa near the lateral margins ; prosternum broad, 

 subqiiadrate. 



Hah. Venezuela. 



This is a somewhat aberrant species, resembling in the 

 fulvous colour, stained more or less with metallic green, the 

 preceding species, but the shape of" the thorax is quite 

 different, not being narrowed anteriorly and very slightly 

 angulate, the surface also is very closely punctured and the 

 elytral punctuation is not so uneven and broken as in so 

 many species, the antennoe have only the seventh joint 

 darkened and are less elongate than is usually the case ; 

 the female only differs in the elytral costoe. 



llhahdopteriis fidvicollis, sp, n. 



Fulvous, the seventh and the apical two joints of the antennae 

 piceous, thorax remotely and extremely minutely punctured, elytra 

 metallic blue, closely and strongly punctured, the base with a 

 transverse depression. 



Length 4 millim. 



Fein. Of oljlong shape, the head fulvous, with a few minute 

 punctures and a shallow central longitudinal groove, clypeus

 surface nearly impunctate, antennae long and slender, fulvous, the 

 seventh and the apical two joints piceous ; thorax more than twice 

 as broad as long, strongly narrowed anteriorly, the sides oblique, 

 with a narrow reflexed margin, the suriace with a few scarcely 

 perceptible punctures, scutellum piceous ; elytra with a distinct 

 transverse depression below the base, closely and strongly punctured, 

 the punctures arranged in somewhat irregular rows, the interstices
