sm.iU box of living specimens of the 

 above mentioned coccid from Prof. 

 Cockerell ; which contained three old 

 females giving birth to young ; all of 

 the others were adult but younger and 

 contained eggs, embryonic larvae, and 

 some with the embryo removed, while 

 others were nearly matured larvae. 

 The three individuals which I have 

 termed old, all proved to have eleven 

 segmented antennae, with the eleventh 

 segment always longest, two and three 

 next, and five shortest ; four, six and 

 seven seem to be nearly equal, as also 

 do eight, nine and ten. The width of 

 the several segments is quite uniform 

 with the first of course as usual broadest. 



(i) 260. (2) 128. (3) 120. There is 

 very little difference in their width after 

 leaving segment four, the average being 

 about 104. Length of middle leg: 

 Coxa 200-260. Femur with trochanter 

 680-720. Tibia 580-600. Tarsus 

 360-380. Claw 108. Width: Coxa 

 420. Trochanter 306-320. Tibia 160. 

 Tarsus 108. Claw 48. The younger 

 forms have ten and eleven segmented 

 antennae ; those with eleven segments, 

 the eleventh were longest, one, two and 

 three next, with five shortest. In the 

 ten segmented forms, ten is longest, 

 then three, two next, then one. The 

 segments of these younger forms seem 

 to be quite variable as do also the 

 middle legs, from the following measure- 

 ments : The eleven segmented form, — 

 Coxa 200. Femur with trochanter 600. 

 Tibia, 480. Tarsus 300. Claw 100. 



The ten segmented form, — Femur 



with trochanter, 560. Tibia 544. Tar- 

 sus 300. Claw 104. Newly hatched 

 larvae, red, elliptical in shape, i mm. 

 long, J mm. broad. Antennae and legs 

 black. Eyes black, large, 56 micromilli- 

 meters in diameter. Antennae six seg- 

 mented, 6 very long, 3 next, 2 and 4 

 nearly equal, i next, and 5 is shortest, 

 although 4 is but very little longer. 

 The formula of their antennae would be

white at first but turn red later on, 

 but when cannot be stated, owing to the 

 fact that all takes place inside of the body 

 of the female. A sketch is given, show- 

 ing the position and size of the genital 

 orifice, just behind the hind legs, and is 

 a known character of Crypticerya. Dr. 

 L. O. Howard seems to have been the 

 first to call attention to this character, 

 together with an exhibition of speci-
