OLIARUB LEPORINUS. 17 



near Marley Wood, at Lul worth, and afterwards in the 

 Isle of Purbeck, and at Ryde, Isle of Wight. Time of 

 appearance, June and July. 



The narrow head and yellowish elytra will easily 

 separate this species from the next. My figure is from 

 the cabinet of Mr. J. W. Douglas. 



Length, with wings closed, 5*08 millimetres, or 

 0*220 of inch.

 Edw. i. 51. 



Large, general colour blackish, with reddish keels 

 and eyes. Crown broader than long. Contour of 

 head, with eyes, somewhat circular ; together narrower 

 than prothorax. A transverse keel occurs between the 

 eyes. Frons yellow. Elytra clear and hyaline ; stig- 

 matic patch marked. Nervures brown on a fuscous 

 membrane. Scott says " finely granulated," but I 

 could not see any such punctuation on the specimen 

 lent to me. Scutellum large and black, with five dark 

 raised keels. Anal tube of the male yellow, with a 

 brown dorsal streak, lanceolate, and obliquely truncate 

 behind. A triangular lobe at its extremity. — (Fieber). 



The figure on my Plate is from a specimen taken 

 by Mr. E. Saunders, in August, on the Tamarisk 

 {Tamarix gallica), at Heme Bay. The same Entomolo- 

 gist also captured specimens at Deal, in June, on the 

 same plant. 



A larger specimen was lent to me by Mr. Douglas. 

 Fieber says that the insect is scattered over the greater 

 part of Europe, but its appearance in Britain has been 

 rarely recorded.
