taken feeding in the manner described by Britton. Also observed 

 on these plants at various other localities in Pennsylvania and in 

 Connecticut. 



Phytonomus meles Fab. This imported species has not yet been 

 recorded from Pennsylvania. It is represented in the collection of 

 the Bureau of Plant Industry from Cresco, Pa., V 1-2-18, coll. by 

 H. B. Kirk; Uoxborough, Pa., VI-6-1!, F. Haimhach, collect.. r. 



'Dorytomus indifferens (.'asey, identified by Prof. H. C. Fall. This 

 species was beaten from Suli.r spp. on June 26th at Harrisburg, Pa., 

 and was exceptionally common. 



Dorytomus subsimilis Hlatchley. Identified by C. A. Frost as 

 nearest this species. Poplar catkins collected by (.'. X. Greene were 

 infested heavily by Curculionid larvae. The larvae left the catkins 

 and entered the ground about April loth. One adult reared. 



Otidocephalus myrmex Hbst. In Blatchley and Leng, Rliyn. 

 X. F. Am., this species is recorded as abundant on hickory, grape. 

 hazel, oak and other plants. 



The sycamore trees in the vicinity of Harrisburg are attacked 

 by the sycamore blight. 



"This disease is common over the eastern range of the sycamore, and 

 in some sections it kills back the young twigs so severely each spring 

 that a pronounced zigzag branching habit results. The fungus, Gnomoma 

 vetieta, is a bark parasite, which is most active in the period between the 

 beginning of spring warmth and the advent of cambial growth, which 

 soon becomes sufficiently rapid to bar further progress down the twigs. 

 Later on, in summer, there are produced in the bark of the twigs already 

 killed the characteristic pimple-like pustules of the fungus, from which 

 the creamy spore masses oo/e in wet weather."'' 



These dead or dying twigs are in turn attacked by Otido- 

 cephalus )iiyniic.r and it is possible that they do their part in 

 spreading the disease. It would be of interest to know if this 

 condition exists in other localities where this blight occurs. 

 Nearly every dead twig examined contained from one to four 

 larvae of this beetle and occasionally the larva of Lciopns alpha. 

 They all work in the slender blight-killed stem, completely 

 hollowing it out. The adults of Otidoccphahts upon emerging 

 in confinement, glass jars being used for cages, feed upon the 

 fungus pustules on the bark, chewing off the top of the- pustule, 

 leaving a round scar. \V. A. Mcl'ubbin. riant Pathologist 

 of the Bureau, to whom these specimens were submitted.
