PRACTICAL ENTOMOLOGY. 4^5 



proximal third, then rapidly narrowed and bristle-like. Sides of the face very 

 narrow, with five rather strong bristles, situated near but not upon, the border 

 of the facial grooves. Dorsum of thorax wholly shining black, without gray 

 dust, with rather strong bristles. Pleurae faintly grayish dusted. Scuttellum 

 with four strong bristles, directed backward. Abdomen ovate, shining ; the sec- 

 ond,third, and fourth segments in the middle, each with two pairs of rather strong 

 bristles, forming two longitudinal rows, the first pair situated a little before 

 the middle, the second pair a little before the posterior border of each segment ; 

 on the lateral borders of each of these segments there are also two, less 

 strong, bristles, situated as the median ones are, but forming a single row; 

 fifth segment and below near the anal orifice with numerous bristles. Legs 

 black, not shining, with numerous bristles. Tegulaj white. Wings nearly 

 uniformily lightly tinged with blackish, more distinctly so along the costal 

 border and the cross-veins; veins dark luteous, except the two outer cross- 

 veins which are black; costa to a little beyond the termination of the second 

 vein, and the third vein as far as the anterior cross-vein, with short black 

 bristles, the first vein bare; cross-vein at outer part of the first posterior cell 

 considerably bent and its anterior part directed outward, posterior cross-vein 

 gently sinuate. 



One specimen, reared by Professor Cook from- the larvae of Agrotis fennica, 

 an immature specimen \7ith0ut wings, sent with this has the same structure of 

 the antenna} ; whether it belongs to the same species or not it is impossible to 

 definitely say. Brauer, in his recent valuable review of the larval forms and 

 habits of diptera, makes no reference to this genus, and the only reference 

 that I can find to the habits of any species is the following from Schiner 

 (Fauna Austriaca, i, 539) : "I possess one specimen of Scopolia reared from 

 an Agrotis larva; nothing further concerning the metamorphoses is known to 

 nie." 



THE STRAWBERRY CROWN GIRDLER. 



liY CLARENCE M. WEED. 



Oliorhynchus ligneus OUv. Order, Coleoptera. Family, Otiorhynchidx. 



A small pinkish or white footless Grub girdling the crown of Strawberries in May- 

 or June. 



This new pest, for which I propose the above name, was first noticed in the 

 college strawberry beds on June 8, by Mr. James Troop. As the larva and 

 its mode of working are similar to the crown borer, it was at first supposed 

 that this famous pest had been introduced, but an examination at once 

 showed that it was a different insect, nor could it be referred to any other 

 species known to attack the queen of summer fruits. Its identity remained 

 in doubt, until on June llth, a newly transformed beetle was found which 

 was kindly determined by Mr. E. A. Schwarz of the Department of Agricult- 

 ure as Otiorliynclius ligneus. 



NATURAL IIISTOIIY. 



It seems probable that the insect hibernates in the beetle state, but 

 whether it also passes the winter as a larva is not known. A near relative, 

 {Oliorhynchus sulcatus) which injures strawberries in Europe hibernates as a
