Dec. 1897.] Webster : Notes on Coleoptera. 203 



Our Coccinellidse do not appear to have many Hymenopterous para- 

 sites. I have, however, the dried skin of a nearly fullgrown larva of 

 Coccmella g-7iotata Hbst., probably, punctured by several round holes, 

 showing that a parasite had developed within and several individuals 

 made their escape. Just what the parasite is, aside from its being a 

 Hymenopter, I cannot conjecture, but the h( les for escape are un- 

 mistakable. This was found at Painesville, Ohio, August 5th. 



Valgus canaliadatus Fab., Plate X, Fig. 5. This has come to be 

 a fruit tree pest in southern Ohio, where the adult works very serious 

 injuries by eating out the fruit buds of the pear and other fruits, in 

 spring. I can find little regarding this habit in our literature, the 

 single instance of this injury being recorded in Insect Life, Vol. i, p. 

 53, where Mr. W. W. Meech, Vineland, N. J., stated that the adult ate 

 out the young buds of the quince. The larvae are known to develop in 

 decaying wood, and my assistant, Mr. Mally, has found the beetles 

 hibernating under decaying stumps. 



Crioceris asparagi Linn., is making its way slowly but steadily 

 west and southwest into Ohio, seemingly spreading more rapidly in 

 these directions than to the southward. There is hardly a doubt but 

 that it has made its way through New York, and along the south shore 

 of Lake Erie, between the lake and the Alleghany Mountains, broaden- 

 ing out in its area in northwestern Pennsylvania and northeastern Ohio. 

 It now covers the area laying east of a line drawn from a point located 

 some distance west of Cleveland, to near the point where Ohio, Penn- 

 sylvania and West Virginia corner upon each other, and the Ohio river 

 ceases to form the boundary line betv/een the two States and passes into 

 Pennsylvania at this place. Professor A. D. Selby, Botanist of the Ohio 

 Experiment Station, informs me that an introduced plant, the Golden 

 Hawk-weed, Hieracium aurantiaciwi L., a native of the Alpine regions 

 of Europe, and introduced into this country prior to 1818, without 

 much doubt, is now apparently spreading over Ohio from western Penn- 

 sylvania in almost exactly the same way. 



In regard to Oberea bimacjilata Oliv. , I have only to again call at- 

 tention to a point already published, unillustrated,* in regard to the 

 astonishing amount of excreta evacuated by the larvse during the space 

 of 24 hours. The adult is shown, slightly magnified, in Plate X, Fig. 

 I, the larva, also magnified at the left. These larvse burrow out the 

 center of the twig as shown in Plate X, Fig. 2, cutting out round holes
