INSECT NOTES. 39 



COLEOPTERA. 

 (Beetles.) 



Carpophihis hemipterns. 



Alany of these beetles and their larvae and pupae were found 

 in a box of California dried peaches sent to the Station for 

 examination from a storage house in Portland. The beetle 

 (fig. 15) which is about ^ of an inch in length may readily be 

 recognized by its short wing covers which are not produced 

 over the last 2 abdominal segments. The insect is mainly dark 

 brown in color; the legs, the posterior half and a spot near the 

 lateral anterior margin of each wing cover, are yellow. The 

 legs are rather stout, the tibiae are somewhat broadened, and 

 the antennae are clubbed. Both larvae and adults feed in de- 

 caying and fermenting sap, pomace and fruit, particularly im- 

 properly cured dried figs, peaches, apples and the like, and are 

 often associated with mites and the larvae of Pomace Flies 

 (Drosopliila). The insect is very widely distributed, almost 

 cosmopolitan, and once established in a fruit packing house may 

 prove a serious pest. 



The larva or grub is a slender flattened creature about 1-5 

 of an inch in length, white in color with a brownish head and 

 3 pairs of legs. The mouth parts are as shown in figs. 20-22. 

 There is a pair of thoracic spiracles on the second segment, and 

 8 pairs of abdominal spiracles, none on the last segment. Upon 

 the body are a few scattered setae ; on the dorsal surface of the 

 last segment (fig. 23) is a pair of stout pointed tubercles, a 

 stouter pair at the apex and a smaller one at the base of each 

 of the latter. The pupa is of the simple, unprotected type, each 

 abdominal segment has about 4 strong setose spines, largest 

 posteriorly. 



The destruction of all infested fruit by burning, and thorough 

 fumigation of the warehouse by hydrocyanic gas are the only 

 remedies which can be suggested for the destruction of this 

 pest. (Lot 843.) 



Euphoria inda (Bumble flower beetles). 



Large beetles (fig. 16) about ^ of an inch in length, have 

 been reported to the Station several times this season eating
