the elytra and the sudden ending of the seriate foveolae of th# 

 elytra at the beginning of the apical one-third part of the elytra. 

 There is also a difference in the apical joint of the antennae on 

 which in A. amabilis there is a distinct external excavation (but 

 not in the present species). The seriate foveolae of the elytra are 

 in both very similar to those of A. chrysurus, Chevr. Also (dis- 

 regarding colour) near to A. corallipes, Chevr., but differing from 

 it inter alia by the seriate sculpture extending scarcely into the 

 apical one-third of the elytra, while in corallipes it reaches 

 nearly into the apical one-fourth.

A. (Clerus) delicatulus, Bohem. I have taken an Aulicus in 

 the Sydney »eighbourhood which I have no doubt is Bohemann's 

 species. It does not seem to present very strong characters, its 

 most striking feature being I think the comparatively feeble 

 sculpture of its elytra, which consists of rows of transversely 

 quadrate impressions separated by continuous longitudinal inter- 

 stices which are (not, as they are in A. chrysurus, Chevr., thrown 

 out of shape or zigzagged by still stronger transverse interstices- 

 running continuously across several of the rows but) straight. In 

 respect of that sculpture it resembles A. nigrohirtus, but in that 

 species the foveae are considerably larger and deeper, and the 

 interstices (both longitudinal and transverse) are considerably 

 stronger and more cariniform ; in delicatulus the longitudinal 

 interstices are almost flat, and carry a straight row of fine and 

 not very closely placed punctures. The sculpture of the median 

 part of the elytra does not in A. delicatulus abruptly cease or 

 change its character at a more or less considerable distance from 

 the apex (as it does in many species of Aulicus) but merely 

 becomes near the apex a little feebler and less seriate. The hind 

 tibiae and tarsi are unusually slender, which suggests the idea 

 that A. viridissimus, Pasc. (also from Sydney) may be a later 

 name for the same insect. Pascoe's statement that in 

 A. viridissimus the elytra are "coarsely" punctured in rows- 

 seems perhaps inconsistent with such identity, but the expression 

 is not altogether inapplicable to the elytra of the insect before 

 me absolutely ', although comparatively {i.e., compared with most 

 other Aulici) the sculpture is not coarse. Some remarks seems 

 to be called for on my having placed delicatulus in my tabulation 

 (above) with A. JPlutus, Chevr., as having the longitudinal 

 channel of the pronotum exceptionally long, whereas Bohemann 

 says of its pronotum " breviter canaliculate." Bohemann calls it 

 by the name " Clerus" however, and it is in comparison with that 

 of other Aulici that I call the longitudinal channel of its pro- 

 notum elongate. Absolutely, the channel maybe called "short" 

 as it does not reach the base, and does not nearly reach the front 

 margin, of the pronotum.
