/ lignicolor as well as in the curious occurrence of white spots at 

 the spiracles of joint ii as noted above. There does not seem to 

 be any character to separate the larva of / ligyiicolor generically 

 from Schiztira. 



The larva of 6". leptinoides is protected by its resemblance to a 

 brown dead piece of Hickory leaf, and it has the habit of leaving- 

 pieces of leaf partly eaten off which soon wither and become brown ,^ 

 like the larva. It girdles the stem of the leaf that it is about to feed 

 upon, causing it to bend down and be more easily reached. This 

 habit is shared by 6^. ipomccE. 



NOTE ON LEPISMA DOMESTICA Pack. 



By E. Ber(jROTH, Forssa, Finland. 



In his synopsis of the North American Thysanura, Prof. Packard 

 has described, under the specific name of doinestica, a remarkable 

 new Lepisma living in the houses about hearths and fire-places at 

 Salem, Mass. From Packard's description there can be no doubt 

 that this species is congeneric with the European Lepisma furnorum 

 Prov., upon which Grassi (Bull. Soc. Ent. Ital. xix, 1887) founded 

 the subgenus Thermophila, elevated to the rank of a genus by Ou- 

 demans (Tijdschr. v. Entomologie xxxii, 1889), who published a 

 more complete description and an excellent colored drawing of the 

 insect. Thertnophila seems to be well distinguished from Lepisma, 

 especially by the six-jointed maxillary palpi, but the name being 

 twice pre-occupied in entomology (Lepidoptera and Coleoptera) I 

 propose to substitute that of Thermobia. 



Thermobia furnomm was detected in the Lombardy by Rovelli 

 in 1884, and has lately been found abundantly in the bake-houses 

 at Amsterdam by Oudemans. It lives in similar situations as the 

 American Th. domestica, which, judging from the description, is 

 nearly allied to, but specifically distinct from the European species. 



In accordance with custom, and for the last time in Entomo- 

 LO(iiCA Americana, ye editor wishes all our readers and friends a 

 Happy New Year. J. B. S.
