tinctly less evidently striate than those of *S'. fall ax, Westw., and 

 more evidently than those of S. decipiens, Westw. The prothorax 

 is not at all explanate on the sides, the elytra broadly so, but 

 very indefinedly, much less definedly than in fallax. S. Icevis, 

 Cast., is perhaps the species to which the present one is nearest, 

 but it is too briefly described for any clear idea of it to be 

 formed without seeing the type. Tt seems however to be differ- 

 ently colored having a " reddish lateral margin to the thorax and 

 elytra " (there is no trace of such coloring in the present species) 

 and having the " thorax bi-impressed on the posterior part " (the 

 present species has no inequalities that can be called distinct 

 impressions) ; moreover it is from a very distant locality (tropical 

 Queensland) ; the probabilities therefore are decidedly against 

 identity.

ADELOTOPUS. 



A. mica7is, sp. nov. Angustus, elonsjatus (quam A. filiformis, 



Cast., parum latior; nitidus; glaber; antennis palpis pedibus 



pronoti lateribus elytrorum apice corporeque subtus plus 



minus ve piceis vel rufescentibus ; capite sat lasvi ; pro- 



thorace quam longior sesquilatiori, antice parum (quam 



A. hoemorrhoidalis, Er., multo minus fortiter) angustato, 



sparsim manifeste (quam A. filiforinis, Cast., multo minus 



crebre) punctulato, lateribus quam A. filiformis, Cast.> 



paullo minus rectis paullo magis late recurvis ; elytris ut 



prothorax (sed apicem versus magis crebre) punctulatis, 



nullo modo striatis, sutura prope apicem vix subcariaata; 



prosterno baud carinato. Long., 3 1.; lat., 14 1. 



Resembles A. filiformis, Cast., and aphodioides, Westw., in its 



pronotum and elytra being very much more distinctly punctured 



than those of dytiscoides, Newm., hydrobioides, Westw., 



netnosomoides, Westw., hcemoy^rhoidalis, Er., &c. From aphodioides 



it differs inter alia by its puncturation being much less close and 



the sides of its prothorax straighter and very much less strongly 



recurved. 



S.A. (Quorn). 



A. Tasmani, sp. nov. Angustus, elongatus (ut A. filiformis, 



Cast.); nitidus; glaber; ut A. micans coloratus; supra 



baud punctulatus ; prothorace (puncturis carentibus 



exceptis) fere ut praecedentis A. inicantis sed lateribus 



etiam magis anguste recurvis ; elytris (puncturis carentibus 



exceptis) fere ut praecedentis, sed sutura baud carinata ; 



prosterno fortiter carinato. Long., 2f 1.; lat., 1 1. 



A very narrow species, of the form of A. filijormis, Cast., but 



differing from that species inter alia by its upper surface being
