sumac. There is much doubt about the identity of the species on all of 

 the above food plants. The only way to be sure about these Pulvinaria 

 spp. will be to get a large number, say 25 or 50, of each and measure all 

 the antennse and legs. (Ckll. in litt.) 



(43) Ptdviiiaria inmimerabilis, var. tilite ; King and Ckll.; 1898-1S98. 

 A variety readily recognized from hinuvierabilis by the colour of the 



female scale, which is gray with several black spots, giving it a mottled 

 appearance. Found at Methuen and Lawrence, Mass., on Tilia avieri- 

 cana, white oak, and elm. 



(44) Pulvinaria Machirce, Kennicott in Fitch ; 1855-1898. N. 



What I take to be this species is found on Sumac. It is the largest 

 of the Ptih'ifiaria type found here, and not very often found. It has 

 been recorded from New York, New Mexico, and Pennsylvania, on Osage 

 orange. 



(45) Lichtensia vibur?ii, Sign.; 1 873-1 898. I. 



The species is new to America and was found at Lawrence, Andover, 

 and Methuen, Mass., on leaves of Spircea salicifolia, L., and Prijios 

 verticillatus. It is parasitized by Aphycus Lounsburyi, How, Ur. 

 Howard, who has so kindly determined all the parasites of my rearing 

 from coccids, also says (in litt.) that he agrees with me that the supposed 

 Pulvinaria innutnerabilis from different localities and food plants needs 

 further study. 



THE MEDITERRANEAN FLOUR MOTH AGAIN. 



BY PROF. W. G. JOHNSON, COLLEGE PARK, MD. 



Some few weeks ago I had an inquiry referred to me by the Editor 

 of the American Miller from a Canadian correspondent, who stated that 

 the flour moth was less than fourteen miles away from his mill, in 

 Wellington (Ontario) district. I contributed a short article regarding 

 this moth in the May number of the American Miller^ in response to 

 which two other localities have been discovered. One comes from York 

 district, along the Lake, and one from Leeds district, along the St. 

 Lawrence River. It seems clear to me that this insect is spreading 

 along the watercourses of the lakes and inland along the railroads. 

 Four other cases were reported to me, with larvae and pupce from each, 

 from the United States side, one coming from Ohio, the first reported 

 from that State, and three from New York. I also have one from 

 Southern California. In every instance the pest has maintained it§ 

 former reputation as a most dangerous insect.
