Phytophagous Coleoptera. 445 



Genus aulacophoka, Chevr. 



1. Aulacophiira te-'<tacea, Fal). Maut. las. i, p. 87 (178D) = 

 abdomlnalis, var. Fab. Ent. Syst. ii, p. 23 (1792). 



Hab. The Hills o£ Assam. 



This Aulacophora, specimeus of both sexes of which are before 

 me, was originally described by Fabricius under the above 

 specific name, and was subsequently, both in the Ent. Syst. and 

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

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

 as a distinct species — the principal points of difEerence between 

 it and foveicollis, Kilst.* 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. fuoeicollis) 

 is plane, quadrate, and of e({ual length with the other lobes; the 

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

 sex of foveicollis. 



2. Aulacophora cornuta, n. sp. 



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

 mineque nigris, pube adpressu argenteo-sericea sat dense vestitis; 

 thorace transverso, disco trausversim impresso, fere impunctato, 

 lateribus distincte, subremoto jmnctatis ; elytris distincte punc- 

 tatis. Long. 4 lin. 



Mas. Antennis articlo basali incrassato, subtus compresso; 

 clypeo utrinque infra antennas cornu lato compresso brevi, apice 



* The name abdom'nialh. Fab. as far as relates to our European species 

 must fall— Fabricius in the Spec. Ins. p. 151, originally described this 

 insect 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.foretoolli><, Kilst, ranges 

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

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

 South Sea Islands it is replaced by closely allied but specifically distinct 

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

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

 longer extant, it will be next to impossible to determine.
