ready shown that Mihniella and interpunctella were only dimorphic 

 forms of one species. The larvae figured and described by Professor 

 Riley as those of interpunctella (Fig. 30, a b d) are in reality those of 

 the Angoumois Moth {OelecMa cerealella'^. Oliv.), with which they agree 

 (see Report Commissioner Agriculture, 1884). That they do not repre- 

 sent Epliestia is shown by their not having the long bristles so charac- 

 teristic of deltoid larvte. 



The dark form, Insect Life, Fig. 30, should be known as huhniella^ 

 the light form, ihid.^ Fig. 28, as interpunctella {zece). 



NOTES UPON SOME INSECTS AFFECTING CORN. 



By F. M. Webster. 



Clivina impressifrons. — Under date of June 11, 1890, I received from 

 Mr. William E. Lawrence, of Whitley County, Ind., a considerable 

 number of these beetles with the statement that "they were found in a 

 piece of ground which had been broken the preceding spring, the field 

 being swampy and of a black soil, like those infested by wire- worms. 

 The beetles attacked the seed grains as soon as the latter became 

 moistened." 



When received one of the beetles had burrowed into a kernel of corn, 

 in the vicinity of the germ, and was engaged in devouring the sub- 

 stance. 



Ligyrus rugiceps. — On April 25, 1888, this beetle was observed de- 

 stroying corn in Tensas Parish, La., and on May 14 still greater num- 

 bers were observed working a like injury in St. Francis County, Ark. 

 Considerable damage had been done by the pest in this last locality, 

 and the beetles, at night, were literally swarming about the lighted 

 lamps. In both instances the injury occurred on clay soils. 



Euplioria sepulchralis. — This beetle was observed at La Fayette, on 

 August 16 of the present year, eating into the kernels of corn, on the 

 tips of ears, in the fields. Mr. L. O. Howard states that he observed 

 this same insect depredating upon corn in the same manner in Georgia 

 in 1881. 



Sphenophorus ochreus. — The finding of eggs in the stems of Scirpus, 

 growing in fields where the beetle was very abundant, and these eggs 

 seeming to agree with those dissected by myself from the ovaries of 

 feuiales, would appear to indicate that the egg may be deposited in the 

 stem of the plant after the manner of other species of Sphenophorus, 

 and not always in the root. 



Calocoris rapidus. — In a former report I stated that these insects were 

 sometimes to be found attacking the kernels of ripening wheat. Dur- 

 ing the fall of 1888 they were observed at La Fayette, Ind., engaged 

 in puncturing the exposed kernels on the tips of ears of corn, and ex-
