and two broad transverse scarlet bands, interrupted at suture and 

 connected at margin ; sutural spine small. Front short, vertical ; 

 prothorax longer than wide. Antennae like preceding. A specimen 

 in the collection of Mr. Ulke is entirely black.

Both are short, stout insects, resembling a rather stout Lamiine. 

 The body is densely clothed with long, coarse, luteous hair, with 

 some denuded spots on the thorax and elytra ; the former is quad- 

 rate transvere, scarcely rounded on the sides and coarsely punctured; 

 the flatter a little broader, truncate at tip, more faintly and \'ery 

 sparsely punctured, with several rows of very distant larger punc- 

 tures. ' ' A. do7'salis is closely related to R. confiisa, but differs by 

 ' ' the prothorax being less transverse, almost quadrate and scarcely 

 " rounded at sides, except near apex, where it is suddenly narrowed. 

 ' ' The arrangement of the denuded spots is somewhat similar, but 

 ' ' the sides of the thoracic vitta are straight and the elytral spots are 

 " confluent, forming a vitta extending nearly to the tip with two ex- 

 " ternal dilations" (Lee. 1. c.) 



LEPTUROIDES. 



The fourth and last division of the Cerambycinse is characterized 

 and divided as follows : 



Base of antennas not enveloped by the eyes, which are entire or emarginate, 

 and usually finely granulate ; front coxje conical (except in Dis- 

 tenia); stridulating plate of mesonotum divided by a smooth space 

 or furrow. 



Mandibles scalpriform, not fringed Disteniini. 



Mandibles simple, not fringed Desmocerlni. 



Mandibles acute, fringed on the inner margin. 



Elytra abbreviated Necydalini. 



Elytra not abbreviated. 



Front nearly vertical Encyclopiui. 



Front oblique, or horizontal Lepturini.
