186 COCCINELLID.E. 



An inspection of the type of B. Mpartita in the Crotch collection leaves no doubt in 

 my mind that the above names apply to the sexes of the same species. It is apparently 

 not common. 



We figure a male from Toxpam. 



3. Brachyacantha aymardi. (Tab. X. fig. 18.) 



Nigra; capitis fronte maculisque duabus magnis transversis ad angulos antieos prothoracis flavis; elytris rufis, 

 sutura tenuiter, macula communi suturali juxta basin, et duabus alteris discoidalibus, una subhumerali, 

 una majore subapicali, nigris. Long. 4-5 millim. $ . 



Hab. Mexico, Parada (Salle). 



Two specimens of this species are before me, agreeing very closely ; they are clearly 

 allied to B. westwoodi, but are larger than that species (with the exception of one 

 specimen from Yolos, of which the determination is a little doubtful), aDd differ, 

 moreover, in the large yellow mark on the anterior angles of the thorax. This mark 

 occupies the whole angle, and extends along the side almost to the base; it is 

 prolonged obliquely into the disc, leaving the front margin black. The body beneath 

 is black, the tibiae and tarsi yellow. 



This insect was labelled Brachyacantha aymardi in the Salle collection. 



4. Brachyacantha cryptocephalina. (Tab. X. fig. 19.) 



Nigra ; elytris sanguineis, sutura tenuiter, punctisque tribus nigris, uno subhumerali, duobus pone medium 

 transversim approximatis, nigris. Long, vix 6 millim. $ . 



Hob. Mexico, Ventanas in Durango (Hoge). 



Entirely black, with the exception of the elytra, which are of a rich blood-red colour, 

 with the suture (narrowly at the base, more widely at the apex), and three small spots 

 on each, black. 



This fine species cannot be confounded with B. aymardi, as it is larger, the head and 

 thorax are wholly black, and the elytral markings are different. 



The single specimen obtained by Hoge is the only one I have seen. It is apparently 

 a female. 



5. Brachyacantha dentipes.
