E. sextieniata has been described by Stejneger as a distinct species 

 on the groimd of the exclusion of the subocular from the labial 

 margin, coupled with the presence of 6 light streaks instead of 5. 

 But, as shown by Tornier, and as I am able to confirm, the two 

 ■characters do not always go hand in hand, and there are besides 

 intermediate conditions, such as the subocular reaching the oral border 

 on a small point only, or incompletely severed from the labial below it. 

 Although it is a fact that the condition of the subocular is pretty 

 constant in specimens from one and the same locality, I do not think 

 the retention of E. sextxniata on this character alone would be justified 

 even as a variety. I have, nevertheless, in the following table, arranged 

 the specimens in two groups according to this character, in order to 

 convey a correct idea of the variation in the series at my disposal. 

 I must add, however, that 40 specimens collected at Morogoro by 

 Mr. A. Loveridge answer, without an exception, to the definition of 

 the typical E. spekii.
