Genus Brachyacantha Chevr. 



Brachyacantha manni sp. nov. 



Color: head, thorax, legs and meso-episternum of cf straw yellow; the posterior 

 portion of the pronotum being piceoiis with two somewhat rounded prolongations 

 of the same color rimning forward towards the disk. 



9 with head black, a large straw yellow spot on the occiput; pronotum black 

 with anterior angles straw yellow. Elytra shining black with five straw yellow 

 spots on each elytron arranged as follows: a triangular humeral, a large juxta-scu- 

 tellar almost touching the humeral, a large squarish marginal near the middle, an 

 oval spot somewhat behind the middle and placed about half its mdth from the 

 suture, and a transverse oblong sub-apical spot rather closer to the margin than 

 to the suture. Ventral surface piceous except meso-episternum which is straw 

 yellow. 



Form rounded oval, convex. Head thickly and finely punctured; Pronotum a 

 little more coarsely punctured than the head; Elytra not so thickly pimctured as 

 the pronotum, the punctures being as a rule about the same size but becoming rather 

 coarser at the sides. Ventral surface; meso- and meta-sternum very coarsely punc- 

 tured, the abdominal segments being much more finely punctured. Length 2 mm. 

 Width 1.5 mm. 



Type cf 9 in my collection, cotype in the Stanford University 

 Collection. 



Type locality. Independencia, Parahyba, Brazil, 1911, 4 speci- 

 mens (Mann and Heath) . 



The cf has the fifth ventral segment deeply excavated almost 

 to the fourth ventral suture, this character bringing the species 

 into Leng's fourth group near B. albifrons Say. The tibial spurs 

 are very small and sharply pointed. Tliis species comes close to 

 B. propria Kirsch as regards the position of its spots, but can 

 readily be separated bj^ its yellow coloring. I take great pleasure 

 in naming this pretty species for its discoverer, Mr. Wm. M.Mann.
