1875.] _ 151 



A single epccimen, in Dr. Sharp's collection ; taken in flood-refuse 

 on the banks of the jS^ith, near Thoruhill, Dumfries, October, 1873. 



The structure of the antennae at once distinguishes this species 

 from all others known to me. These organs are very short (suggestive 

 of Cijrtusa), gradnally widened towards the apex, with the 4'th, 5th, 

 and (;th joints nnusually small, and the apical joint, though shoi't, as 

 wide as the two jirecedijig (which are very transverse), and forming a 

 capitulum larger than in A. ovalis. 



The tliorax is evenly rounded at the sides, and almost truncate in 

 front, with the anterior angles much rounded off; its surface is deli- 

 cately and not very closely punctulated ; the elytra are coarsely, but 

 not very deeply, punctate-striate, the punctures being not so sharply 

 defined as, but larger than, in A. dubia.

A single ? specimen, from Dr. Sharp's collection. 



This species may be briefly described as the equivalent to A. 

 rugosa, in the section with linear front tibiae. Apart from the tibial 

 character, it differs from rugosa in its rather smaller size and more 

 oblong form, unicolorous antennal club, longer and more strongly 

 punctured thorax, of which the sides are not dilated, but contracted in 

 almost a straight line from the base to the apex (the hinder angles, 

 though obtuse at the point, being almost rectangular), in the punctures 

 of the stria; of its elytra being not quite so closely packed, and the 

 transverse strigosities of the interstices also not so close, the whole 

 surface being more shining. 



Prom J. lij/hrida, it may be at once known by its shorter form, 

 flatter build, lighter colour, more strongly punctured thorax, coarser 

 stritc, &(.-. 



The elytral punctuatioii in this species is quite unlike lliat of 

 A. mullipunctata and circinipes, mihi, from .lapaii ; and A. Jatcriiia, 

 Mann., from Sitkha, differs at once from it in its transverse thorax, 

 dark club, &c.
