often prove a greut jinnoyance to the entomologist, since they jire as 

 fond of the batlies of dried insects as of any of the above named 

 snbstances. 



Fig. '2. Dermcstcs lardarius Linn, a, larva; h, one o( its barbed hairs ; c, beetle. 

 (After Riley). 



These pernicious little beetles make their way into our houses in 

 May or June, and at once deposit their eggs on their favorite food if 

 they can obtain access to it, or, if they find this impossible, they 

 frequently lay their eggs near small openings or crevices so that the 

 young when hatched may make their way in to the coveted articles of 

 food. 



The full-grown larva (Fig. 2, a) is about one-third of an inch in 

 length, of a brownish color, tapering somewhat from the anterior to 

 the posterior extremity. It is clothed with long rough hairs (Fig, 2, 

 6), and has a pair of short curved spines on the top of the last 

 segment. 



The perfect beetle (Fig. 2, c), is from one-third to one-fourth of 

 an inch in length, black, with a broad gray band across the base of 

 the wing-covers, upon each side of which are three .small black spots. 

 The under side is black with a yellowish tinge. 



Dr. Hagen states that if pieces of old cheese be placed in favorable 

 situations, the beetles will be attracted to them, and may then be very 

 easily destroyed. 



CLOTHES MOTHS. 



There are three different species of clothes moths in this country, 

 all of which were undoubtedly imported from Europe, where they 

 have been known from the earliest times. 



The first of these moths {Tinea tapetzella Linn.) is quite rare in
