Family Coccinellid.7-;. 



Psyllobora plagiata, new species. 



Size of 20-maculata, punctuation slightly finer; thoracic spots similar hut not as 

 heavy as in the average 20-maculata. Elytra with two spots on each side of base, 

 two median subsutural spots and below these a large, broad, more or less angulate, 

 oblique black patch and three spots of variable size near side margin, the first slightly 

 antemedian, the second below this but further removed from the margin than the first 

 and third, the latter situated at about apical fifth and on each side of suture a sub- 

 apical spot. Under side of body as in 20-maculata. 



Huachuca Mts., Arizona. 



Some of the spots near suture or side margin may be absent or 

 very faint, but the large postmedian patch is always present. 



Brachyacantha arizonica, new species. 



Slightly smaller and more rounded than ursina, similarly marked, but without 

 median spot on lateral margin and with basal spots always continent. Head pale in 

 the male ; pale at middle, black at apical margin and infuscate at sides in the female. 

 Thorax black, apical margin and a large triangular spot at sides pale in the male, in 

 the female the apical margin very narrowly and a narrow subtriangular spot at apex, 

 which extends slightly below middle, pale. Elytra black, two basal spots on each 

 side, large and always broadly confluent, a large rounded, discal spot near suture 

 and large apical spot nearer the margin than sutuie yellowish or reddish. Punctu- 

 ation of thorax and elytra as in ursina. Under side of body black ; legs pale in the 

 male; femora piceous, tibiae and tarsi pale in the female. Anterior tibiae with the 

 usual tooth near base, and in addition a smaller, but more obtuse one near apex.
