470 ANNUAL REPORT SMITHSONIAN INSTITUTION, 192r) 



whole proleg structure by tlio movement of wliich it must be ex- 

 panded and contracted so as to take and relax its hold. 



The true legs are rather small and rather thick, and densely, or 

 at least very closely and regularly, clothed with fine white hairs. 

 They terminate in a claw, slightly hooked, slender as compared with 

 the last joint of the leg, dark in color, making it look very strong 

 and sharp, and capable of being flexed so as to fold up on to the 

 last (tarsal) joint of the proleg, renjinding one of the tibiae of Neya 

 or Mantis. 



The head is nearly colorless, about 1.7 mm. wide. Centrally below 

 the mouth and pointing backward is the labium, or part of it, a 

 pale conical rather than cylindrical process ending in a short 

 chitinous tube (spinneret?). On each side is a long palpus 

 (maxillary?) of three joints, the last very small, projecting ven- 

 traily and apparentl}'^ with a fleshy process (maxilla?) toward the 

 middle line. In front is a tolerably normal labrum, square and 

 notched below, with a good many short hairs on its anterior surface. 

 The antennie are very long, about 1.1 mm., and regularly clothed 

 with fine hairs; Doctor Chapman could not recognize a basal joint, 

 if there be one; the next, therefore the first, is very long, 1 mm., 

 and also thick, about 0.22 mm. The last joint is a small square piece 

 about 0.1 mm. 



The labrum is very fixed in its position and moves little. Doctor 

 Chapman says that even if he is deceived in this matter by having 

 only stiff preserved specimens to deal with he is certain that it fits 

 down very closely and tightly laterally in the maxillary bases, leav- 

 ing in front an oval opening between it and the labium within which 

 the jaws are visible, with apparently some room for movement in 

 the cavity thus formed. 



Each jaw carries three teeth, each a long sharp spine capable of 

 piercing, but certainly not of biting. P^ach jaw is probably capable 

 of meeting the other, so that the teeth ma}'^ interlock; but in the 

 specimens examined one jaw is entirely in front of the other. 



There are six eye spots, five of them in a circle, the other separate. 



The head, which looks sunken into the white fleshy tissue of the 

 under side of the larva, is really very moveable and has a definite 

 neck ( ? ) , so that the mouth parts, which are at the front of the 

 head and point more or less forwards, can be directed directly 

 backwards between the true legs, exposing the front or dorsum of 

 the head, which is rather longer than broad, nearly colorless, and 

 has some hairs and the usual suture marking off the clypeus. 



Doctor Chapman also had a larva of intermediate size which 

 differed from the larger one in nothing except, perhaps, that the 

 spiracles were more readily seen than in the full grown one.
