CURCULIONID^. HYLOBIUS. 107 



rounded : elytra oblong-ovate, with a callous towards the tip ; shoulders ob- 

 tusely angulated : femora clavate, more or less unidentate : tibits with the 

 apex furnished with a hook within. 



Hylobius differs from the foregoing germs, to which it is allied, 

 by having the elytra free and the body winged, exclusively of its 

 other distinctions : all the known species delight in the sap of fir- 

 trees of various kinds. 



Sp. 1. Abietis. Nigro-piceus, opacus,Jlavescenti-pilosus, thorace antice coarctaio, 

 elytris tenuiiis cancellato-striatis, interstitiis valde rugosis fasciis macularibus 

 Jlavescenti pilosis. (Long. corp. 5—9 lin.)

 Don. V. XV. pi. 529. 



Pitchy-black, opaque: head thickly rugose-punctate, with an impression between 

 the eyes, and a tuft of flavescent hairs near the latter : thorax thickly and 

 deeply rugose-punctate, with an obsolete central carina, and some scattered 

 yellowish hairs on the sides and dorsal line: elytra with cancellated strise, 

 the interstices ruggedly tuberculate, with several spots composed of yellowish 

 depressed hairs, and disposed in irregular fasciee, varying somewhat in different 

 individuals; an abbreviated one towards the base, near the suture, but not 

 touching it, and an oblique one laterally rather behind, are most constant and 

 distinct: the sides of the abdomen have also some tufts of similar hairs, 

 forming a row of spots : legs pitchy-black. 



Rarely found in the south of England, but apparently very 

 abundant in the north, whence I have seen hundreds of speci- 

 mens : how far south it extends in plenty I am not aware, but it 

 has been frequently captured in the fir plantations in Norfolk.

tSp. 2. Pinastri. Nigro-piceus, subnitidus, cinereo-pilosus, thorace lateribus 

 rotundato, elytris profunde cancellato-striatis, interstitiis subtiliiius rugosis, 

 fasciis macularibus albido-pilosis, pedibus rufis. (Long. corp. 6 lin.) 



Rh. Pinastri.— G3///eraAa/.—Hy. Pinastri. Steph. Catal. 170. No. 1742. 



Pitchy-black, slightly shining : head, rostrum, and antennae rufo-piceous : thorax 

 with the sides rounded, sparingly clothed with cinereous hairs : elytra rather 

 deeply cancellate-striated, with the interstices finely rugose, adorned with two 

 rather distinct Jiijciw of whitish hairs, and other scattered irregularly placed 

 ones: body beneath slightly clothed with ashy hairs: legs elongate, rufo' 

 ferruginous ; femora acutely dentate. 



I believe there is a specimen of this insect in the collection at the 

 British Museum, which was taken in Scotland.
