 Hypsauchenia guttiplaga, Walk. MS. 

 Hypsauchenia hardwickii, Walk, (nee Kirby), Jouru. Linn. Soc, Zool. 



x. p. 183(1868). 



Brownish-ochraceous ; face piceous ; tegmina and legs a 

 little paler ochraceous ; tegmina with a subapical transverse 

 fascia o£ five or six white spots, commencing at costal but not 

 reaching inner margin; anterior pronotal process compressed, 

 upwardly concavely erect at base, and then somewhat 

 straightly continued to above the apex of tegmina, narrowed 

 neu- its apex, which is strongly bilobed, the apex of each 

 lobe laminately triangularly widened, before apex distinctly 

 tricarinate, the carina? at basal front distinctly paler in hue, 

 the posterior process broadly concavely erect and compressed 

 beyond middle, the central ridge very finely serrate, darkly 

 coarsely punctate, on each side at base a curved, linear, 

 longitudinal, pale ochraceous ridge. 



Long. 10| mm. 



Hab. Celebes ; Tondano (Wallace, Brit. Mus.). 



This species seems to have been originally recorded by 

 Walker as hardioickii, Kirby, and on subsequently noticing 

 the error was then labelled, but not described, as guttiplaga. 



Pyrgauchenia suberecta, sp. n. 



Dull bronzy brown, the legs and basal pronotal ridges pale 

 ochraceous. Allied to the preceding species, P. sarasinorum, 

 Bredd., but much darker in coloration, the tegmina lacking 

 the white macular fascia ; the anterior pronotal process much 

 more erect, upwardly concave, its apex scarcely passing the 

 apical region of the posterior process (extreme apex muti- 

 lated), posterior process coarsely punctate, but less convexly 

 elevated before apex. 



Long. 9 mm. 



Hab. S. Celebes, Bua-Kraeng (H. Fruhstorfer) . 



Pyrgauchenia jugulata. 



Hypsauchenia jugulata, Buckt. Trans. Linn. Soc. Lond., Zool ser 2 



vol. ix. p. 332, pi. xxi. fig. 12 (1905). 

 ? Pyrgauchenia breddini, Schmidt, Stett. Ent. Zeit. lxvii. p. 370 (1906). 



Hab. Sumatra; Swlak Daras, Korinchi Valley, 3100 feet. 



Buckton's description and figure represent a mutilated 



example in which the anterior pronotal process is mutilated.
