42 Mr. Charles J. Gahan's Revision of 



Head and prothorax yellowish-testaceous ; head closely punctured, 

 especially in front ; prothorax somewhat closely punctured on the 

 dorsal and lateral tubercles, sparsely elsewhere. Elytra violaceous 

 from the base almost to the middle, and thence to the apex pale 

 fulvous or yellowish ; the costae obsolete or represented only by 

 very feebly raised lines. Body underneath and legs pale testaceous, 

 but with a large spot on each side of the metasternum, black, and 

 the anterior abdominal segments sometimes infuscate at the sides. 

 AntennsB of the male reaching to or a little beyond the apex of the 

 elytra ; first four or five joints fulvous or testaceous, last six or seven 

 fuscous. 



Hah. Java (Hors field), Penang (Lamb), Borneo, 

 Perak, Burma, and Si am. 



In Pascoe's collection, I found two examples of this 

 species from Penang, and one from Sarawak, mixed up 

 with those of another species under the name of splendida, 

 Fab. The coloration of dimidiata greatly resembles that 

 of splendida, Fab., but the two species are easily dis- 

 tinguished by the structural characters given for the 

 respective sections in which they are here placed. 



8. Astathes limaculata. 



Cerambyx Mmaculatus, Fab., Ent, Syst.,i, 2, p. 263 (1792). 

 Astathes externa, Pasc, Trans. Ent. Soc. Lond., (2) v, p. 46 

 (1859). 

 Yellowish-testaceous or fulvous ; elytra each with a rather large 

 and somewhat rounded violaceous spot placed just in front of the 

 middle, extending thence about half-way to the base, and, in the 

 transverse direction, reaching from the outer margin to within a 

 short distance of the suture ; metasternum with a fuscous spot on 

 each side ; antennas slightly infuscate towards the apex, the first 

 three joints nitid and sparsely setose, the remaining joints pubescent 

 and dull. In structural characters agrees very closely with A. 

 dimidiata, Gory, but in general form is relatively a little longer and 

 narrower than that species. 



Rah. South India, Tranquebar, Madras, Trevandrum, 

 Bangalore. Type in Copenhagen Museum. Type ($) of 

 externa, Pasc. in Brit. Mus. 



The Fabrician description of this species appears to 

 have been overlooked by the authors of the Munich 

 catalogue, as I can find no reference to it in that work. 

 From Fabricius's description I had strongly suspected that 

 his species was identical with the A. externa of Pasc. ; and
