liiokin Kivrr, {'jinterhtirv, Mr. J. II. Lewis scoured two 

 speeiiuens ; the one retiiiiied by bini is even l)rij^bter, quite 

 scarlet in fact. Tlie fiery siiuauiosity is distinctive. 



Acalks alius, sp. n. 



Compacl, very convex, subovate, rouj^h, densely covered 

 with obscure greyish scales ; autennse and tarsi fulvesccnt ; 

 rostrum pitchy red. 



Jiostrui/i thick, gradually narrowed towards the middle, 

 «hcre tiie antennie are inserted. Scajfe reaching backwards 

 to the eye; funiculus 7-arti<'ulate, basal joint nearly as thick 

 at apex as the scape, second more slender, nearly twice the 

 length of third ; seventh distinctly broader than the pre- 

 ceding ones ; club ovate, triartieulate. Thorax ratiier longer 

 than broad, inucl) but not abruptly narrowed anteriorly, its 

 frontal portion depressed; across the front of the basal 

 portion are erect scales which almost form a pair of crests ; 

 it projects over the head, l)ut is much shorter below. Head 

 globose underneath, but distinctly depressed above between 

 the eyes ; this tiattened part is blackish. Elytra very sliglitly 

 wider than thorax at the base, short and subovate, ami quite 

 vertical behind : when examined from tlie side they are seen 

 to be on an abruptly higher level than the thorax; they arc 

 also convex transversely ; on the summit of the liind declivity 

 tliere is a pair of prominent crests, there is also a less promi- 

 nent one ou each side, but not so far back. Leys stout and 

 scaly. 



Underside covered with greyish scales, all the coxje almost 

 equally widely separated. Pectoral canal deep and broad ; 

 its raised margins extend almost to the front of the inter- 

 mediate coxie. Metasternum abbreviated, so that the middle 

 and hind coxtC nearly touch each other. Abdomen punctate, 

 basal two segments ou a higher plane than the short third 

 and fourth, the second apparently very short. 



The thorax doubtless is punctate and the elytra striate- 

 punctatc, but as the specimen may be needed afterwards in 

 its natural condition, i have not spoilt it by scraping. 



Like A. cristatus (127G), more sombre of aspect, with less 

 obvious and fewer crests, and distinguished by the inter- 

 ocular depression. No doubt a new genus will ultimately 

 be formed for these two species.
