Essay, Brit. Form. p. 131. 

 Nyland, Form. Fr. et d'Alger. p. 98, 26. 

 Hab. Britain, North America and Brazil. 



This insect may now be regarded as cosmopolitan, I have ex- 

 amined numerous specimens from the above localities ; Say was 

 the first who described it, and who records its habit of intruding 

 into houses. The Rev. Hamlet Clark brought it from Brazil, 

 with this character : — " It is found everywhere and upon every- 

 thing." Its native habitat, I think from this, must be Brazil, and 

 that it has been imported elsewhere in merchandise. 



Dr. Nylander has placed this insect in his eighth subdivision, 

 which embraces the species belonging to the (Ecophthora of Heer, 

 but an examination of a winged individual shows that it has only 

 one submarginal cell, and that the discoidal cell is obsolete in the 

 male. Should this prove to be the case in the females also, a new 

 subdivision or genus must be established for its reception.
