92 THE CANADIAN ENTOMOLOGIST. 



To Mr. Louis H. Joutel, the artist-naturalist, we are indebted for the 

 important disclosure, some unknown Papaipema larv?e found by him in . 

 the pine barrens of New Jersey ultimately proving this very desirable 

 species. The discovery happened at an early stage, and when later 

 it became assured that we were dealing with an unknown larva, a 

 subsequent visit to the locality extended our acquaintance to a small 

 but thriving colony. 



A first visit to the pine barrens is frauglu with many surprises, the 

 extremely distinct flora and fauna of such a district being a never-failing 

 source of enjoyment. One looks in vain for the usual thick-stemmed 

 weeds in which our boring friends are wont to occur, but tlie soil 

 conditions debar such a growth • in fact, one looking for them alone 

 would soon give up in despair. The herbaceous plant life runs to all 

 sorts of odd creations, with orchids and sundews and a host of bright 

 flowering plants in a variety of forms that bring joy to the heart of the 

 botanist. .Strange noises are in the air, as large, unfamiliar Hymenoptera 

 buzz past. Even the Cicada's note sounds queer, and the long-drawn, 

 monotonous bur-r-r-r proves to be produced by an unfamiliar form. 

 Only the mosquitoes, the untold hosts of mosquitoes, are thoroughly 

 familiar, and even here very likely many distinctive species exist, though 

 the ordinary mortal is more intent on the virtues of some repellant, rather 

 than on the variety of species that may be feasting upon the exposed 

 l)ortions of his anatomy. So it is not strange, after all, that such a locality 

 should produce some unlooked-for novelty. 



When coming to hand the young larv?e were apparently past second 

 moult, the first pair of abdominal legs being still aborted, so that a 

 slightly-looping position occurs when moving. It still on occasion would 

 spin a silken thread when sliding from an insecure footing or upon a 

 sufficient apprehension of a fall. Appearance is very similar to 

 purpurifascia, and there exists a way of working that strongly recalls this 

 species. There appeared only one difference : with purpurifascia the 

 dorsal line is continuous, with our friend of the pitchers it is suppressed 

 on joints four to eight. In the succeeding stage developments bespeak a 

 greater individuality. We have the typical Papaipema larva, of exceed- 

 ingly cylindrical build, the longitudinal stripes queerly broken at its 

 middle. The colour is a good shade of sienna, somewhat livid, the dorsal 

 and subdorsal lines ]iure white. The tubercles, thoracic and anal plates 

 are all very pronounced and follow the usual positions. On joint ten
