88 COLEOPTERA. 



Hylesinus jiolygraphuSy Ratz., Forstins., Kiif., 182, 

 T. vii, f. 12. 



A few specimens of tliis interesting wood-feeder, belonging 

 to a genus new to our lists, were, taken at the end of last 

 summer, under fir bark near Scarborough, by Mr. R. Lawson, 

 to whose accustomed liberality I am indebted for the insect. 



The genus Polygraj)]ius, Er., is readily separable from the 

 other Hylesinides by each of its eyes being almost entirely 

 divided into two parts, through an encroachment of the 

 canthus ; by the 3rd joint of its tarsi not being wider than 

 the 2nd; and by the non-articulate club of its antennae, 

 which is very large, flattened, and ovate, and considerably 

 longer than the funiculus, which is onIy4-jointed. Chapuis, 

 I. c, forms a sub-tribe, Polygraiyhidcu^ expresslj'' for its 

 reception. 



The insect can be superficially compared with Hylastes 

 ohscm^us, Marsh., which it somewhat resembles in size, build, 

 and colour, but from which its delicately and confusedly 

 granulose-punctate (not striate) elytra, clothed with scanty 

 scale-like pubescence and very short setae, and its anterior 

 tibiae being dilated in a much less degree and less abruptly, 

 and being only slightly denticulate-serrate on the outer edge, 

 will readily distinguish it. 



91. Cryphalus granulatus, Ratz., Forstins., Kaf , 164, 



T. xiii, f. 19; Redt., Fauna Austr., Ed. 2, 832; 



D. Sharp, Cat. Brit. Col. ; Ent. Mo. Mag., viii, 



84. 



In Dr. Power's collection (taken in June, 1867, near 



Surbiton) ; confirmed by Herr EichhofF. 



It is very like C. h'uiodulus, but considerably larger, with 

 the funiculus and legs partially yellow, and the stria; of the 

 elytra distinctly punctured near the suture.
