she must liavo several eggs ready for laying. While in the air 

 Avith her vietiiii, her abdomen could be seen curved towards it; 

 she is provided with a sharp corneous ovipositor, with which 

 she either pierces the hopper's body oi- inserts her very small 

 egg (not seen) under a body fold. At any rate the liberated 

 homopteron seems unhurt and usually hops away. If the 

 young hopper is too large, the fly is sometimes apprised cf the 

 fact by being hurled back by the insect's vigorous leap. 



In catching recently pipunculated hoppers, I found it best 

 to sit down before a sort of clearing among cane plants, shake 

 down a number of hoppers and place leaves bearing many 

 young, in suitalde positions and wirh a whiti- cloth or handker- 

 chief held beneath her, carefully but (piickly follow a burdened 

 PipiincuJus. As soon as the hopper is liberated, it falls on 

 the cloth and a wide-mouthed vial is clapped over it. I was 

 unsuccessful in many attempts but numaged thus to secure 6-7 

 parasitized hoppers in about an hour. 



The life of the young Pipiinculus is rather long, inasmuch 

 as it is not ready to leave its host's body until some time after 

 the latter has become mature. Then a male hopper thus 

 parasitized develops a much swollen abdomen, but I was not 

 able for certainty to distinguish similarly affected females. 

 The latter often have the body noruuilly swollen with eggs, 

 but when pipunculated, these eggs are consumed by the grow- 

 ing parasite. In its early stages, the maggot is rather soft and 

 delicate, in later development it is decidedly tough ; then it is 

 tinged with orange, is wrinkled and active and short-oblong in 

 shape. 



On April 12th, I captured a few small hoppers which had 

 been caught \\\) and dropped by Pipuncuhis. Some of these 

 Avere successfully transported to the Experiment Station in 

 Honolulu, whei-e five of them nuitured in the tirst part of 

 ^lay. By IMav 14th one male was seen to have a swollen 

 abdomen and thus to be certainly parasitized but unfortunately 

 it died shortly thereafter. The last of these hoppers to die, a 

 shoi't-wiuued female, did so on ^Mav 20th, and her abdomen
