This Aulacophora, specimens of both sexes of which are Ijeforc 

 me, Avas originally described by Fabricius under the above 

 specitic name, and Avas subsequently, both in the Ent. Syst. and 

 Syst, El., reduced to a variety of abdoiainalls; an examina- 

 tion of these specimens has convinced me that it must be regarded 

 as a distinct species — the principal points of difference between 

 it and foveicoUis, Kllst.* are as follows : the transverse groove 

 on the thorax is less deeply excavated, and the abdomen is 

 entirely black in both sexes, the anal segment in the $ is as 

 usual trilobate, but the medial lobe instead of being longer than 

 the lateral ones and longitudinally concave (as in A. fooeicolliv) 

 is plane, (|uadrate, and of equal length with the other lol^cs; the 

 anal segment of the 9 ^-Iso differs in form from that of the 

 same sex of foveicoUis, 



2. AulacopJwru cornuta, u. sp. 



Oblouga postice pauUo ampliata, flava, nitida, pectore abdo- 

 mineqne nigris, piibe adpressa argenteo-sericea sat dense vestitis; 

 thorace transverso, disco transversim impresso, fere impunctato, 

 lateribus distincte, subremote punctatis ; elytris distincte punc- 

 tatis. Long. 4 lin. 



Afas. Anteunis articlo basali incrassato, subtus compresso; 

 clypeo utriuque infra antennas cornu lato compresso brevi, apice 



* The name rihihiuiiintli.i. Fab. as far as relates to our European species 

 must fall — Fabricius in the Spec. Ins. p. 1.")], originally described this 

 iusect from a specimen in Forster's Cabinet, brought from one of the 

 islands in the Pacific Ocean: subsequently some individuals from India 

 and the Cape of Good Hope (regarded by him as belonging to the same 

 species) came under his observation, thus in his later works, he gave 

 those localities as Habitats for the species. A./orricoUis, Kiist, ranges 

 over Southern Europe, the north of Africa, and a considerable extent of 

 Continental Asia : but in the Malay Arcliipelago, Australia, and the 

 South Sea Islands it is replaced l)y closely allied but specifically distinct 

 forms, one or other of which doubtless must be regarded as the true 

 aMnrninaHs, which of them unfortunately, from the type being no 

 longer extant, it will be next to im]iossil)le to determine.
