THE YOUNG NATURALIST. 



light grey, the following seven are ruddy, like those described above, the next 

 seven vars. from very dark well marked specimens, to almost Gothicina form, 

 followed by seven vars. Gothicina, some of these have no indication of stig- 

 mata or of the usual " Hebrew character/' the row being finished by seven 

 specimens all varying from each other, one being quite as dark as the dark- 

 est form of T. instahilis or T. qpima I ever saw, yet still the Hebrew charac- 

 ter is well pronounced in all of them. In the seven Gothicina var. named 

 above no two are alike, and one only approaches the form of the five recently 

 bred, it will thus be seen how difficult it is to say what is Gothicina, except 

 we adopt the canon laid down in Robson's new list " without the black 

 marking between the stigmata/' but the fact that five per cent of the bred 

 specimens have thrown back to the grandmother, and that one half of the 

 balance being dark well pronounced grey drabs, seems to point to drab 

 grandfather, of course is not proved, but in the first case I think we may 

 fairly say it has been shown that fugitive species have thrown back to the 

 grandmother.

BlapS similis* This species is broader, with shorter legs, and more dis- 

 tinctly punctured, it occurs in houses and bakehouses, in the South of Eng- 

 land. 



Blaps sulcata is a very large species, one of which I obtained at Ashton- 

 under-Lyne ; it was found in Egyptian cotton, in which it had probably been 

 imported from Egypt, it was living when I received it. According to Eabri- 

 cius the women in Egypt eat this species, which is cooked in butter in order 

 to make them grow fat, it is very common in that country. 



Tribolium ferrugineum is often found in bran and flour, on which 

 the larva feeds. It has also been found in profusion in cotton goods, doing 

 great damage, probably in consequence of the goods being heavily sized with 

 flour. 



Tribolium COnfusum is often found in bran and flour, in bakehouses 

 and provender stores. 



Gnathocerus COrnutllS is common in bakehouses, cornmills and 

 granaries, the larva feeds on flour, meal, &c.
