One of Mr. Champion's examples represents a variety (fig. 3) of this beautiful species 

 in which the dark purple velvety elytra are unicolorous, with the exception of four 

 rather small yellow marginal spots in the situation of the lateral terminations of the 

 fasciae and apical spot of the typical form. Mr. Janson in describing the male calls 

 attention to the extraordinary form of the mentum, the disc of which is produced as a 

 stout vertical spine, remarking, justly, that no trace of this exists in the male of 

 A. anomala, and only a slight indication of it in the male of A. lansbergei. 



We figure two male examples from Bugaba. 



CHIEIQUIBIA. 



Gen. Allorhince affinis, sed differt capite maris absque cornu frontali, fronte ab occipite longitudinaliter usque ad 

 cornu clypeale obtusissime carinata. Clypeus apice medio cornu mediocri erecto, bifido, capite margine 

 utrinque prope oculos alte et acute elevato, apice acuto et libero. Tibiae 4 posticas sat graciles, inermes, 

 anticEe ( S ) apice extus in spinam acutam prolongatse et obsolete obtusissime bidentataa. Processus 

 sternalis (sicut in Gotine) latus, planus, apice late rotundatus. £ ignota. 



One fine and large species only is known of this genus. The absence of horizontal 

 frontal horn necessitates its separation from Allorhina (inch Tiarocera, Burm.), from 

 the species of which it also differs strikingly in colour and markings.
