58 THE CANADIAN ENTOMOLOGIST. 



Dr. Mayr, in " Die Europaischen Torymiden," in a foot note gives the 

 synonymns of this genus as follows : 



Podagriofi Spinola. Ann. du Museum d'Hist. Nat., xvii., 1811, p. 147, 



Faimon Dalman. Vet. ac. Handl., 1825. 



Priomerus Walker. Ent. Mag. I., 1833, p. 118. 



Bactyrischioji Costa. De quib. nov. Ins. Gen., 1857, p. 5, f. 4. 



Several species in this genus are known to science, and it is a remark- 

 able fact that the habits of only one species are known, Podagrmi (Pal- 

 tno7i) religiosus Westwood, and that that also should be parasitic on 

 Mantis eggs (Mantis religiosus). 



NOTES ON THE LARVAE OF HARRISIMEMNA 

 SEXGUTTATA, Harr. 



BY CHARLES F. GOODHUE, WEBSTER, N. H. 



During August and September the larvae of this fine moth are often 

 seen feeding on the lilac. When full grown it is of peculiar shape and 

 markings, and taken altogether, a hideous looking object, and one which 

 i<f^^ people besides an entomologist would care to have anything to do 

 with. 



Mature larva, 1.75 inches long. 



Head and adjoining segment black, segments 3 and 4 yellow with 

 black points, segments 5, 6 and 7 are brown varied with white, and 8, 9 

 and 10 are white, 11, 12 and 13 are brownish black. It is deeply incised 

 between the segments, and the abdominal feet are long, especially the 

 first two pair. Segments 6 and 12 are much produced dorsally, being 

 very pointed; this, together with the habit of arching the body between the 

 anterior feet and the long abdominal ones, causes it to present a very 

 irregular and jagged outline. 



On the top of all the segments are a few rather long scattering hairs. 

 It has the peculiarity of retaining the cast off skin of the head and part of 

 second segment on these hairs, which are not shed with the rest of the 

 skin ; first near the tip of the hairs the head case is small, a little below 

 this is another, and so on. We have quite often seen three of these cast 

 off skins on a larva at one time. 



They will, if ever so slightly disturbed, raise the front part of the body 

 back to the abdominal feet, and thresh it violently from side to side ; in 

 fact, their heads shake nearly all the time, like a person with the palsy.
