NO. 7 RICHARDS : THE GENUS BULIA WALKER 261 



The 6 types come from two localities which are onlj'^ about 35 miles 

 apart. Mr, H. R. Roberts tells me that these are both on the margin of 

 the central plateau of Mexico in what is generally called a subtropical 

 area. The town name alone is not definite, as a great range of altitude 

 occurs within a few miles; even so, these localities are well removed 

 both from low altitudes and from deserts. 



Named in honor of Dr. William Schaus, who collected the paratypes 

 and who has done more work on neotropical Lepidoptera than any other 

 individual. 



Bulla morelosa, new species 



Fore wing gray irrorated with dark gray. Faint double basal line ; t. a. 

 line black, double; median space concolorous with rest of wing except 

 where crossed by the darker median shade line; reniform normal; t. p. 

 line obsolete except near costa; subterminal line light, complete, defined 

 by preceding and succeeding darker ground color. Hind wing and under 

 sides as usual in genus ; the dark border of the hind wing of moderate 

 width. 



Expanse: 30 mm. 



Female genitalia: (pi. 33, fig. 5) Sternite VII deeply indented, with 

 narrow blunt median prong and broad squarish lateral lobes. Other fea- 

 tures as in deducta and similaris except that the unique mated female of 

 morelosa has a rounded bursa copulatrix instead of constriction into 2 

 regions ; this, however, might conceivably be an accident of either mating 

 or manipulation during preparation of the slide. 



Halo type: $, Cuernavaca, Morelos, Mexico, June, 1906 (ex Schaus 

 Coll., inU.S.N.M.). 



The town of Cuernavaca is on the southern and Pacific slope of the 

 central plateau of Mexico. Although only a little more than a hundred 

 miles from the localities where schausi was taken, Cuernavaca differs con- 

 siderably from these localities, particularly in having some surrounding 

 desert country. In keeping with this desert habitat (where the author as- 

 sumes this specimen was collected), morelosa comes closest to the desert 

 species of northern Mexico and southwestern United States. Of these 

 large series are available, and sternite VII has been examined by the 

 author on well over 200 specimens of deducta and on about 30 specimens 

 of similaris (including race calif ornica) . None of these had this short but 

 narrow median prong, and none such broad blunt lateral lobes. These
