well. The intervenular dots are not so prominent as in 

 some other species. 



Beneath primaries slightly brighter yellow than 

 above, but lacking the numerous strigse. The bands 

 show through as above. Secondaries are same as 

 above, only lacking the strigge. 



The females are larger than the males and the bands 

 at inner margin are more interrupted, and they lack 

 prominent forked bands. 



The gentalia afiford the best characteristics for sep- 

 aration. See Figure 5G. 



Penis broad and heavily armed with stout spines on 

 side near distal end ; the ampullae are very broad and 

 high; the harpe is most striking, rising beyond the 

 upper costa somewhat like the head of a bird with 

 the beak poinaed towards the top of the valvae; the 

 ceros is long and broad, being heavily armed with 

 stout spines ; the lower costa is slightly serrate. 



Expanse c? 33 to 35 mm. ? 40 to 46 mm. 



Holotype c? Dallas, Texas (Boll), and in the mus- 

 eum of Comparative Zoology collection at Cambridge, 

 Mass. 



That there may be no confusion of terms I will 

 state that the penis as a whole is made up of two parts, 

 an outer firm covering, generally called the adseagus 

 and an inner eversible tube called the ductus ejacula- 

 torius or true penis.
