94. M. carnosa Biickton var. impatientis (Williams) {Siph. carnosa 

 Buckton var. impatientis Williams). 



" Siphonophora carnosa Buck. var. impatientis n. var. No. 

 127. On Impatiens pallida, W., Aug. 22, 1890." 



Two other slides bearing the same data as above but numbered 

 "128" and "129," respectively, are examined. Slides number 

 127 and 128 bear only pupae and immature wingless. No. 129 

 bears one wingless viviparous female adult and several pupae. 



Wingless viviparous female: Segment III of the antennae with basal 

 half swollen and bearing 9 circular sensoria in a row. One of the cor- 

 nicles completely gone and the other broken off at the middle, so that their 

 characteristics cannot be described. Only one of the antennae is measur- 

 able—Segment III, 0.98; IV, 0.79; V, 0.66; VI, base, 0.178; VI, filament, 

 1.24; total length, including the two basal segments, 4. 114 mm. Length of 

 body, 2.63 mm; to tip of style, 2.99 mm. 



Camera lucida drawings of the antenna and style of wingless 

 viviparous female are given on Plate V, figs. 89 and 90. 



94. M. chrysanthemi (Oestlund) (Siph. chrysanthemi Oestlund). 



95. M. sanborni Gillette {Siph. chrysanthemicolens Williams). 



"Siphonophora chrysanthemicolens n. sp. No. 131. On 

 Chrysanthemum in greenhouse, Omaha, Jan. 13, 1891." 



Only wingless individuals on the slide. This is a synonym 

 of Gillette's M. sanborni described in the Canadian Entomologist, 

 40: 65, Feb., 1908. 



96. Microparsus variabolis Patch (Siph. dcsmodii Williams). 



" Siphonophora desmodii n. sp. No. 133. On Desmodium 

 canescens. West Point, July 29, '90." 



On this slide is one or possibly two wingless adults, the others 

 being immature. This species is synonymous with Patch'.s 

 Microparsus variabolis, described in Entomological Nezvs, 20: 

 337, Oct., 1909. I have recently received this species from Dr. 

 C. C. Adams who collected it on. Desmodium at Charleston, 

 Illinois. The species has not heretofore been reported from 

 Illinois.
