THE CADELLE. 



black; abdomen and elytra red, except for tip and two 

 black spots on each elytron. Carpophilus hemipterus 

 is an introduced species which is found in grocery and 

 bakery shops. It is about .17 in. long; black, except for 

 the pale legs, a dull yellow shoulder-spot and an irregular 

 area of the same color covering the distal half of each 

 elytron. Omosita colon is often seen on greasy bones in 

 the back yard. 



The LATHRIDIID/E are rarely more than .1 in. long. 

 They are usually reddish-yellow or brownish. Most of 

 the species occur under bark and stones, or in decaying 

 leaves; some are found on plants and some, e. g. Corticaria 

 ferruginea, in dried products such as drugs. 



TEMNOCHILID^E 



There are not many species and most of them live 

 under bark. 



Two species, mauretanica (the Cadelle) 

 Tenebrioides 



and corticahs, are found in granaries 



throughout the world. The eighth antennal joint of 

 mauretanica is equal to the ninth; in our other species it is 

 smaller. Plate LXXVII is sufficient additional descrip- 

 tion of the blackish adult Cadelle. The dark areas shown 

 in the illustration of the larva are reddish brown. It 

 feeds on wheat, flour, and other foodstuffs. The fact that 

 it has been found in milk has been used to help prove 

 that milkmen enrich their goods with cornstarch. This 

 larva seems to be rather hardy as Webster recorded its 

 feeding on hellebore. It is said also to feed on other 

 insects and it has been known to bore into the wood of 

 grain bins. 



The PARNID^E are small (less than .25 in.) beetles which 

 cling with their long tarsal claws to sticks and stones in 

 water, often even in swift streams. The flat, circular 

 larvae occur in the same places, clinging tightly to their 

 support. Neither stage swims. 



It may be of some use to name the families we now 

 skip. It would be of little use to describe them, as the
