Length of Second Nym-phal Stadium. Of the two second nymphs 

 obtained, one transformed in five days into the adult; the other, 

 strange to say, Uved in its cell for 32 days without transformation. 

 At the end of this time it accidentally escaped. During this period 

 it frequently became quiescent but at no time did it undergo 

 transformation. 



Description of Second Nymphal Instar. Very similar to the adult; beak and palp* 

 showing more chitinization than in the first nymph. Beak and palpi very similar to 

 that of the adult. Palpi stout, extending beyond the tip of the beak by about two 

 fifths their length. Outer seirula of palpal papilla relatively larger compared to the 

 palpal claw than it is in the adult, with 12 teeth; inner serrula with teeth, wherein 

 it differs from that of the first nymph; number of teeth less than that of the adult, 

 being only 9 or 10; curved tactile seta as in adult. Anterior pair of legs shorter 

 than the body exclusive of the beak; tarsus considerably longer than the tibia as is 

 true of the adult. Second pair of legs two thirds as long as the first pair; fourth pair 

 of legs extending beyond the tip of the abdomen by one half their lengthi Total 

 length of the body, including the beak, 48mm.; width, 0.26mm. 



Length of Adult Stadium. The single adult obtained lived for 13 i 

 days and then died a natural death. This period corresponds very well 

 with the length of time some of the adults lived which were not reared 

 from eggs deposited in captivity. 



Description of Adult. A very fight yellow, almost flesh color; palpi and beak 

 darker than the body and legs. Beak as long as the rest of the cephalothorax, more 

 strongly chitinized at its tip than at its base and bearing not far from its tip a single 

 pair of hairs or setae which extend one half their length beyond the beak. Palpi very 

 stout, extending beyond the tip of the beak by two fifths their length. Last segment 

 of palpus ending in a stout, curved, simple claw which extends beyond the tip of 

 the outer serrula of palpal papilla by about one fourth its length. Two spurs or 

 tubercles of about equal size are situated on the inner margin of the segment at the 

 base of the palpal cIslw. Palpal papilla, or thumb, short, stout, as broad as long and 

 bearing two serrulae and a large, curved, tactile seta; outer serrula much larger than 

 the inner and almost as long as the palpal claw, with from 12 to 15 teeth, which in- 

 crease in length as you pass from the base to the tip; inner serrula slightly over one 

 half as long as the outer, with from 14 to 16 teeth, which are longest from the middle 

 of the organ and become shorter as you pass toward the tip or base; curved tactile seta 

 longer than the outer serrula and situated between and slightly below the two serrulae. 

 Antepenultimate segment almost as broad as long; with but two setae which, however, 

 are prominent; one is a large, curved, tactile seta situated on the inner margin of 

 the segment next to the papilla, it is longer than the palpal claw; the other seta is 

 situated on the ventral side of the segment. Femur of palpus one and a half times 

 as long as broad; inner margin concave, outer margin convex. On the upper surface 

 of the femur of the palpus is situated, a very long, simple or shghtly pectinated bristle 

 wluch is shghtly longer than the segment itself. No other bristles on the upper sur- 

 face of this segment. Cephalothorax broader than long excluding the beak. Eyes 

 absent. Anterior pair of legs shghtly longer than the body excluding the beak; 

 tactile hairs on the tarsus sub-equal, and slightly shorter than the tarsus itself; tarsus 

 longer than the tibia. Posterior pair of legs extending for almost one half their length
