every house iu St. Thomas " ; Mr. Schvilz, who apparently did not 

 distinguish the two insects, notes utereVa as the domestic species ; 

 while Mr. Grudmaun found it on the trunks of ti'ees ; and Baron 

 von Hedemann, who found the cases very common on the inner 

 walls of houses, only succeeded in breeding one specimen. The 

 larva of maculata is unknown.

If this species is correctly determined by Mtischler its occurrence 

 in the West Indies is a remarkable contribution to the study of 

 Geographical Distribution. It has not yet been detected in the 

 United States, and a myrmecophilous species could hardly be 

 imported from Europe to Portorico. Moreover, the localities in 

 which it is found in Europe are not such as could warrant 

 the suggestion of its having bfeen introduced from the West 

 Indies.

274. Xylesthia australis, sp. n. 



Antenna' simple ; dusky cinereous. Palpi with the second 

 joint widely and roughly clothed beneath, apical joint almost con- 

 cealed ; cinereous speckled with fuscous. Head and tJiorax 

 cinereous. Fort wiiujs arched at the base, apex depressed, roiuided, 

 termen oblique ; cinereous dusted with fuscous, an indication of 

 an obscure cloud-like fuscous spot at the end of the cell is followed 

 by four cloud-like spots above at the base of the costal cilia ; 

 cilia cinereous, with a fuscous shade-line running through them. 

 Exp. al. 16-20 mm. Hind iviwjs broader than the fore wings, 

 rounded at the apex ; brownish fuscous, cilia the same. Abdomen 

 greyish fuscous. Legs very pale cinereous.

 St. Thomas, 9 III. {Gudmann). Three specimens. 



The male specimen from St. Thomas is more distinctly marked, 

 having fuscous spots along the costal margin, a fuscous shade 

 along the disc from the base, and the terminal cilia are mottled. It 

 seems to be, however, only a well-marked varietj\
