collections. Minerea is usually much more strigillate, however, and 

 has a rather well-defined small lunate reniform, while lunata has the 

 reniform much longer, narrower, and usually indefined superiorly. 

 There is not, of course, any really close relation between the two: 

 hut they do occasionally resemble each other so much as to cause 

 trouble. 



The range of variation has been largely indicated in the descrip- 

 tion. In general there are two types, those with the median space 

 distinctly paler and those with the wings as a whole concolorous. 

 This range occurs in both sexes, and it is quite easy to arrange two 

 very well marked series with limited material. In the males there arc 

 also two forms, those that have the terminal area washed with blue. 

 forming '2 lunate areas on primaries and one on secondaries, and 

 those in which there is only an edging of scales or a blue line beyond 

 the s. t. line. Aside from that almost any one feature may vary in 

 prominence, so that with fifty examples at hand it may be difficult 

 to find two of them exactly alike. 



The spinulation of the median tibia' is obvious in both sexes, and 

 in a fair proportion of cases there are spines between the two pairs 

 of spurs of the posterior tibia'. This feature has been already dis- 

 cussed sufficiently to bring out the range of variation. In the male 

 the sexual tufting of the median femora is distinct and the mass of 

 specialized scales is large and conspicuous. 



The male genitalia are grotesquely asymmetrical. The left harpe 

 i> single, broad at base but rapidly narrowed to a slender flattened 

 strip, which becomes roughened, a little enlarged, and irregular at 

 tip. The right harpe is double; that is, the base is broad and single, 

 but it divides almost at once into a slender upper and lower process, 

 of which the upper is first bowed up, then bent down and furnished 

 with a little prong not far from tip. The lower process follow- the 

 reverse course and bends upward, is also forked toward tip. but the 

 forks are much longer and they almost engage the fork of the upper 

 process. There is considerable variation in the specimens in this 

 forking; but in essentials the structure is identical in all the exam- 

 ples observed. The corneous penis sheath is very sharply bent and 

 really crook-like in outline seen from the side. 



The female is in its way as characteristic as the male and has the 

 terminal segment complete, not divided into lobes. At the extreme 

 right of the segment is a corneous ring which forms the opening to 

 the copulatory pouch, and this is furnished with a single, jointed. 

 cercus-like appendage. A reference to the figures will lie accessary 

 to really understand the structure. 



The synonymy given at the head of this species is probably not 

 complete, but it is as complete as I feel certain about it. Under the 

 name lunata there are at least two and probably three species from
