Longicornia Malayava. 349 



Prolhorax in medio gibbosus, lateiibiis dentatus vel tumidus, 

 postice sulcatus, basi bisinuatus. Elytra latiuscula, ssepis- 

 sime tricarinata, apicibus rotundata. Pedes breviusculi, 

 sequales ; femora modice incrassata ; tarsi breves ; unguiculi 

 basi appendiculati. Prosternum elevatum. 3Iesosternum me- 

 tasterno omnino tectum. 

 The type of this genus, A. perplexa, Newm., is a Manillan in- 

 sect, and is the only species known to me in which the prothorax 

 is strongly toothed ; in all the others there is merely a tumidity, 

 which in some cases is very prominent, including a large part of 

 the side; it is also one of the few species in which the lines on 

 the elytra are scarcely or only slightly raised, although their places 

 are indicated by the absence of punctures, and sometimes of a 

 very delicate line. All the species have a glossy derm clothed 

 with short setose scattered hairs, but the coloration is often a 

 little uncertain. Astatlies perplexa, for instance, generally uni- 

 colorous, has sometimes a large violet spot on each elytron ; and 

 in others the blue or violet varies in extent, or becomes purplish. 

 Nevertheless the disposition of the colours, which are mostly a 

 combination of yellowish-testaceous or fulvous, violet or blue, and 

 black, affords, in conjunction with other characters, a sufficiently 

 satisfactory clue to the discrimination of the species. The gib- 

 bosity of the prothorax rises more or less gradually from the 

 apex, and is often slightly notched behind. Generally the punc- 

 tures on the head and prothorax are few and small ; those on the 

 elytra are in many individuals surrounded by a very evident 

 deeply-coloured border — areolated as they have been termed — 

 but other specimens, which do not appear to be otherwise diffe- 

 rent, have none or only very slight indications of this areolation. 

 Species of this genus occur in Northern India, Northern China 

 and in Japan, but Mr. Wallace does not appear to have found any 

 east of Borneo.

Entirely yellowish-testaceous, except the apices of the antenna>, 

 which are of the usual brownish colour, but rather paler than in 

 the majority of species ; the elytra with a slightly opaline tinge ; 

 gibbosity of the prothorax sloping gradually down in front to the 

 apex and attaining its highest point nearly in the middle of the 

 disk (in A. jierjilexa it is flattened and bilobed in front, without
