common little insect is worth the trouble of mounting 

 whole. It is found amongst dried plants, &c. 



Many other insects may be examined or mounted 

 entire, as 



943. HOUSE ANT (Diplorhoptrum molesta). Rather 

 more free than welcome in many metropolitan houses. 

 Should be caught and mounted whole. 



944. GARDEN ANT (Formica nigra). Either this or 

 the common yellow ant (Formica flava), found in banks, 

 will furnish, with the preceding and succeeding, good 

 representatives of these curious insects. 



945. GREAT WOOD ANT (Formica rufa). Plentiful in 

 woods where fir-trees predominate, building large hillocks. 

 This is a large species. 



946. HOUSE-FLY (Musca domestica). A common but 

 very interesting object. It may be mounted entire in a 

 deep cell, for low powers. 



947. RAIN FLY (Anthromyia pluvialis). Sometimes 

 almost as common in houses as the house-fly. Lighter 

 coloured, and more prettily marked and banded. 



948. GALL INSECT (Cynips Kollari). This insect may 

 be reared from the common gall of the oak, of late years 

 so plentiful in this country. 



949. OAK APPLE FLY (Cynips terminal^). This little 

 fly may easily be obtained from the common oak-apple 

 gall, and is soon developed. 



950. OAK SPANGLE FLY (Cynips longipennis) may be 

 reared from oak spangles, so plentiful on the under sur- 

 face of oak leaves. Leaves that have lain on the ground 

 during the winter should be selected for bearing the 

 insects, which are developed in March. 



951. TWENTY-PLUME MOTH (Alutita polydactyld). 

 One of the prettiest of moths for the microscope, with 

 plumed wings. Commonly beaten out of hedges, and 

 often seen at dusk, in summer, fluttering against the 

 window. 



952. TURNIP DIAMOND MOTH (Cerostoma xylostella). 

 A pretty little moth, common in turnip-fields, in which 

 the caterpillar feeds.
