the light spots occurring for the most part at the apices of the veins ; on 

 the inner (short) fringe scales the light spots occur as far as the 6th long.. 

 on the long scales the spots are distinctly yellow as far as the 5th long., 

 ard merely pale at the apices of the more caudad veins; ist submarginal 

 cell longer (4:3), and narrower than the 2nd posterior, its base nearly one- 

 sixth of its length interior, stem of 2nd posterior much the longer ; super- 

 numerary cross-vein is nearly equal to mid, which it meets, and posterior 

 cross-vein somewhat longer and a little more than its own length distant. 

 These vein positions vary somewhat ; halteres white.

This is a very beautiful and well marked species near M. albirostris, 

 Theob., but the additional broad band on the palpi, and the spotted legs, 

 make it easily distinguishable, while the wing markings resemble those of 

 M. elegans, James. It has only been sent in twice, and the two specimens 

 from which the description was written were collected by Dr. James W. 

 Thornton, Cont. Surg. U. S. A., after whom it is named. 



The specimens of Stegomyia scutei/aris, Walker, sent in early in 

 1903 from Samar, were found to vary from the type, and as these varia- 

 tions occurred in all the specimens from that island, it was decided to 

 create a variety, attention being called to some differences, and the insect 

 was published as 6'. scutellaris, Walker, sub-species Satnareftsis, Ludlow.* 

 Since then a number of very perfect specimens from Samar, Leyte and 

 Mindoro have made the differentiation more perfect, and the complete list 

 of differences is given below. 



Stegomyia scuteilaris, Walk., var. Samareiisis, Ludlow. — This variety 

 differs from the type as follows : 

 L Has two white lateral bands on head ; no bands on antennae of 



female. 

 n. The silvery median line on thorax extends nearly the whole length of 

 the mesonotum, tapering from the cephalic end to just in front of 

 the scutellum, where it divides, forming two short, very fine sub- 

 median lines ; there is also a narrow straight white line on each 

 side, exterior to these, extending cephalad from the scutellum 

 about one-third of the length of the mesonotum, dividing its width 

 almost exactly into quarters.
