(249) 11. * Leptura similis. Similar Leptura. 



L. ( similis ) linearis, niyra, punchdaiissima, corpore subtus ex pvbe subargenteo; ehjtris apice rotundaiis ; antennis scapo femori- 



busque rvfis. 

 Similar Leptura, linear, black, very minutely and thickly punctured, body underneath, rather silvery from down ; elytra 



rounded at the apex ; scape of the antennae and thighs rufous. 



Length of the body 3^ lines. 



A single specimen taken in Lat. 65°. 



DESCRIPTION. 



This may possibly be the other sex of the preceding species which it resembles in every respect, 

 except that the antenna are rather longer, the scape or first joint, all but the base on the upper side, 

 is rufous, as are likewise the thighs and four anterior tibia ; the posterior thighs are however black 

 at the apex. 



(250) 12. * Leptura longicornis. Long-homed Leptura. 



L. [longicornis) nigra, elongata; ehjtris grosse pvnetatis, vitta pedibnsque basi, testaceis ; antennis mediocribus. 

 Long-horned Leptura, black, elongated, stripe of the grossly punctured elytra, and base of the legs, testaceous ; antenna? as 

 long as the body. 



Length of the body 5 lines. 



A single specimen taken in Lat. 65°. 



DESCRIPTION. 



At first sight this species a good deal resembles L. semivittata and gulosa of the former section, 

 but its eyes are entire, and its antenna? much slenderer and of a different type, more nearly resemb- 

 ling those of L. argentata and similis. Body black, minutely punctured, downy, especially under- 

 neath, with silvery hairs. Head minutely, thickly, and confluently punctured ; labrum and base of 

 the mandibles rufous ; last joint of the palpi securiform ; antenna very slender nearly as long as the 

 body ; scape incrassated, rufous, black at the base : prothorax a little constricted anteriorly, very 

 thickly punctured with a longitudinal dorsal impunctured line or channel : scutellum longitudinally 

 concave, rounded at the apex ; elytra nearly linear, grossly punctured, glossy, nearly black, with a 

 pale stripe extending from the middle of the base to near the apex, and gradually approaching the 

 suture : apex subtruncated : legs rufous at the base.
