Ifah. Antilles, St. Vincent {H. II. Smith, Lansdown 

 Gnihling), and Union Island in the Grenadines (//. FI. 

 Smith). 



Redescribed from five males and four females belonging 

 to the British Museum or to the Hope Collection at Oxford, 

 including a ^ from St. Vincent found by Lansdown Guilding 

 and a ? from Union Island, the others nnlabelled, but all 

 probably from St. Vincent. The specimen from the 

 Grenadines, labelled A. antillaruni, var. ?, by Gorham, was 

 not mentioned by him in his description of that species. It 

 is strange that there should be two such closely allied forms 

 in a small island like St. Vincent, but there is nothing inter- 

 mediate in the series of A. gorhami before me, A. antilhirum 

 having the elvtra spotted much as in A. octopustidatus. 

 The emarginate, bidentate apices of tlie elytra is a character 

 peculiar to the ? of these three insects, all of which have a* 

 bituberculate metasternum in ^ .

 cence, the vestiture of the legs and under surface cinereous ; 

 black, the basal joints of the antennae partly or almost 

 entirely red, the elytra with a broad or moderately broad 

 stiipe extending down the disc to the apical depression, a 

 tjansverse subapical patch, and the outer margin to near the 

 apex, these markings sometimes coalescent posteriorly, 

 flavous or orange-yellow; the head and prothorax closely, 

 finely, the elytra roughly, punctured. Head small ; antennae 

 short. Prothorax narrowed anteriorly. Elytra long, sub- 

 parallel, costate laterally from the humeral callus, and with 

 an indication of a faint costa on the disc ; the apices in (J 

 feebly subtruncate or rounded, in ? deeply eniarginate, with 

 the sutural angle drawn out into a long, nariow, nearly 

 straight tooth and the outer angle into a shorter acutely
