it comes near to the Kamendaha group. Tapoosa elegantula Dist. 

 belongs to it and has the first median sector well befor^;the apical thfri^^s. 



Makula Distant. y^ 



Brixia testacea Walk, is a Phaciocephalus^ and^/^i pictipennis 

 Walk, is a Basileocephalus ; they have both been wrongly placed under 

 Makula. 



IjfTERAMMA Walker. 



I. ascendens Walk, must be the type o£ this genus, as it is upon 

 that species the generic description was based. I. august a Walk, differs 

 from the t}'pe, and I. suhvaria Walk, was placed by him in a different 

 section. Nicerta and Mecjatropis are closely allied, and the species 

 placed under them require further study. 



RoBiGUs Distant. 



This genus is stated to have the costal margin " distinctly broken 

 by an irregular, raised, longitudinal, cellular interspace," and is figured 

 with the costal margin broken at the apex of the subcostal cell. The 

 specimen upon which Bohigus is founded has the tegmina bent slightly 

 at this point, the left more so than the right, but there is no such raised 

 cellular interspace as described. Both the wings and the tegmina of the 

 specimens are badly crumpled, as if they were not fully developed. 



B. pattersoni, sp. n. 



Tegmina typical of the genus, the subcostal cell short. Head wider and 

 in profile more produced than in the type species, the antennae reaching 

 slightly beyond the apex of the head. 



Light yellow ; genae before eyes, face, antennae, and ba.se of clypeus 

 bright red. Tegmina yellow with a broken, irregular, longitudinal, bright red 

 mark down the middle, a broken fork proceeds from the first median sector to 

 the apex of the subcostal cell with a small spot between the forKs, a small spot 

 on the hind margin slightly beyond the apex of the clavus, veins coucolorous 

 as in membrane ; wings white with white veins, covered with a fine, powdery, 

 waxy secretion. 



Ventral edge of pygofer straight, entire, lateral edges entire, slightly 

 curved; anal segment large, convex on ventral aspect, concave on dorsal 

 aspect, slightly narrowed at base, wide at apex, which is shallowly, roundly 

 emarginate, each apical corner is produced into a stout spine curved ventrad ; 

 genital styles large, wide, ventral edge curved, entire, dorsal edge straighter, 

 with a small, flat, curved process from the middle, apex [ointed and turned 

 dorsad. 



Length 4 mm. ; tegmen 6 mm.
