A small species allied to T. chilensis^ A. & S., from which 

 it differs by its smaller size, the black lateral margins to the 

 pronotum, the black centre of the cruciform elevation, the 

 much less pilose surface of the body beneath, the less broadly 

 sulcated face, &c. 



Melampsalta luheculata^ sp. n. 



$ . Head and thorax above ochraceous ; head with the 

 margins of front, a lineate spot near anterior angles of vertex, 

 and a very broad fascia between the eyes, enclosing the ocelli, 

 black. Pronotum with two central fascial rounded and joined 

 posteriorly, a spot on each side, and the fissures, black ; a 

 black spot on posterior margin at the lateral angles. Meso- 

 notum with four large obconical spots (the central pair 

 shortest), a central lanceolate fascia, anterior margin of cruci- 

 form elevation, a spot on its anterior angles, and a small spot 

 in front of the same, and the posterior lateral margins, 

 black. Abdomen black, moderately pilose, the posterior 

 segmental margins very narrowly ochraceous; a spot on each 

 side of the last dorsal segment, two large lateral spots (basal 

 and apical), and two central lines to anal appendage, ochra- 

 ceous. Body beneath and legs ochraceous ; a broad central 

 fascia to face on each side of the sulcation, base and apex of 

 rostrum, sternal spots, longitudinal streaks to femora, anterior 

 tibiffi (excluding bases), bases and apices of intermediate tibise, 

 apices of the tarsi, a broad central fascia to abdomen, and anal 

 appendage (the last centrally united with the dark coloration 

 above), black. 



Tegraina and wings pale hyaline : tegmina with the vena- 

 lion fuscous, the costal membrane ochraceous, and with a 

 large blackish spot on the transverse veins at the bases of the 

 second and third apical areas ; wings with the venation 

 ochraceous and fuscous.
