with which it has probably been hitherto confounded ; but it dif- 

 fers from that beautiful species by its pellucid wings, pale tibia, 

 broader bands of the tergum, color of the thoracic hair, and by 

 having silvery hair on the hypostoma and front. It belongs to 

 the second division of the genus, in which the palpi are cylindri- 

 cal, or slightly clavate and recurved.

Desc. Body above rufo-yellowish ; hypostoma chestnut; antennae 

 yellowish-white ; seta black ; palpi and rostrum white ; cheeks 

 somewhat glaucous, with whitish ^jair ; thorax three or five lined 

 with black, the three intermediate lines being obsoletely separate ; 

 scutel immaculate ; wings hyaline, costal margin tinged with yel- 

 lowish ; nervureS; particularly those of the inner margin, those that 

 are transverse, stigmata and tip of the wing margined with fus- 

 cous, more obvious and dilated at tip of the wing, and on each 

 side of those transverse nervures that are beyond the middle ; 

 tergum with a large rounded black spot on each segment, and a 

 black line on the lateral edge. 



Ohs. Very closely allied to L. scolopacea Fabricius, of Europe, 

 but it differs from that insect in several particulars, as iu the 

 color of the antennae, stethidium, feet, &c. The specimen is a 

 male.
