298 Mr. J. S. Baly's notes on 



inaccessibility of the type-specimens, could not be 

 recognised. 



The numbers attached to the species in the present 

 paper correspond with those used in the Synopsis ; the 

 names in italics are those given by M. AUard as 

 synonyms of the insects under which they stand. 



Genus Aulacophora. 

 Sp. 1. coffees, Horns. 

 M. Allard appears to have drawn his short description 

 of the above species from the dark form of A. similis, 

 Oliv., S . 



Sp. 2. 'puhescens, Allard. 

 Judging from the short description, and from the 

 pubescence on the elytra, this insect probably belongs to 

 another genus. 



Sp. 3. ahdominaUs, Fabr. 



M. Allard has evidently made his diagnosis on 

 argyrogaster, Perroud, a New Caledonian form. Perroud's 

 insect differs from ahdominaUs in its larger size and 

 black legs ; excisa, mihi, of which I only know the 2 , 

 has an emarginate apex to the pygidium, in the two 

 other species the pygidium is entire. 



Sp. 5. delata, Erichs. 



foveicolUs, Kuster. 



Overlooking the peculiar sculpture of the head in 

 Erichson's species, Allard has placed together the above 

 distinct forms ; delata is a Tropical African insect ; 

 foveicolUs, formerly confounded with ahdominaUs, Fab., 

 has the front simple in both sexes, and is spread over 

 Asia, Southern Europe, and Northern Africa. It is 

 more than probable that M. Allard has not had the true 

 delata under examination ; Erichson, in his very, clear 

 description, makes no mention of any pubescence on 

 the upper surface of the body ; the thoracic sulcation is 

 also straight, not curved, as described by the author of 

 the Synopsis ; the coloration of the under surface in 

 delata varies from black to entirely flavous.
