Dr. B. Das, of the Government college at Lahore, India, writes 

 (in lift.) under date of December 18, 1913, as follows: 



I have collected it [M. pisi] from Bengal, Behar, United Provinces, and the Punjab. 

 Though not actually collected by myself, I believe it is present in other parts of 

 India as well. What looked like a bad attack on a few plants was observed once 

 on that beautiful flower known as "Glory flower" or "Parrot's beak" (Clianthus 

 dampieri). The hosts of this species, so far known to me besides the above are: 

 Alhagi maurorum, Melilotus alba, Medicago sativa, 21. falcata, Lathyrus odoratus (rather 

 bad once in Behar), Peganum harmala, and Dolichos lablab.

 line, which is, however, indistinct with the pulverulent covering. 

 Eyes black. Antennas four-segmented and blackish green, the last 

 segment apparently black. Legs blackish green, the distal four-fifths 

 of the hind tibiae covered with a bloom giving them a whitish appear- 

 ance and as if covered with a mold. Cornicles blackish green, slightly 

 paler at the base and a black ring marking the rim of the opening at 

 apex. Cauda not visible. 



Measurements of a single individual, made immediately after 

 mounting in balsam and before shrinkage occurs-: Length of body, 

 0.956 mm., width, 0.487; length of cornicles, 0.0695 mm., width, 

 0.037; antennas (the two antennas measured exactly alike), segment 

 I, 0.052 mm.; segment II, 0.043; III, 0.191; IV, base, 0.078; IV, 

 filament, 0.178; total length, 0.542 mm. 



Wingless adult (fig. 2). — (Described from four specimens, Apr. 24, 

 1913.) Body color pale green, the abdomen bearing several dark 

 reddish dots which are the eyes of the embryos within her body. 

 The dorsal and ventral surfaces show a distinct reticulation in living 

 individuals, head bearing a faint pulverulence. Eyes dark red. 

 Antennas more than two-thirds the length of the body but not reach- 

 ing to the base of cornicles; segments I and II concolorous with head 

 and semi translucent, the remaining segments semitransparent with 

 a faint brownish green tint, excepting the tips of III and IV, distal
