h'omm^ epipleuris, Hnea profunda impressa basi apiceqiic 

 abbreviata. Long. 1^ lin. 



^las, tibiis anticis deformibus, intus supra medium dente 

 armatis; trochauteribus anterioribus spinosls, trochanteri- 

 bus intermediis breviter dentatis ; femoribus intermedlis 

 summo basi spinosis, tibiis intermediis unco valido ; meta- 

 sterno late transversim impresso; abdomine segmento 2" 

 ventrali, apice lamina transversa, erecta, fissjl, segmento 

 quinto fovea maxima insignis. 



Antennae longer than head and thorax, 3rd joint longer 

 than 2nd, 5th longer than the contiguous ones ; 8th joint 

 small, 9th larger than 8th, transverse ; 10th longer and 

 broader than 9th, also transverse; 11th joint very large, 

 armed on the inside at the base with a small tubercle, 

 (not very easily perceived). Head impunctate, with two 

 large foveje on the vertex, the front between the insertion 

 of the antennfB depressed. Thorax about as long as broad, 

 convex, distinctly narrowed behind, furnished Avith three 

 fovea", connected by a line, impimctate, except that there 

 are indistinct traces of punctuation near the lateral fovea?. 

 The elytra are rather brighter red than the rest of the in- 

 sect, each has a well marked sutural stria which is deeply 

 impressed at the base, and with a second stria between 

 this and the shoulder ; this stria is well marked, deeply 

 impressed at the base, but abbreviated a little before the 

 extremity, and each is also fin-uisiied on the deflexed por- 

 tion with a very deeply imjjressed line. 



A single specimen only of this extremely remarkable 

 Brt/axis has been brought back by INIr. Lewis. It is no 

 doubt a male, the sexual characters being most prominent. 



]Mr. Lewis has also submitted to me a single specimen 

 of a Bryaxis which may possibly prove to be the female of 

 B. princeps. Besides the absence of the characters above 

 assigned as those of the male of B. princeps, it differs, 

 however, in being smaller, and of a darker, more obscure 

 colour, and has the elytra very distinctly shorter. The 

 antenna, though thinner and shorter than in the male in- 

 dividual, are similarly formed, except that I can see no 

 tubercle on the 11th joint. Ha-snng a strong impression 

 that, notwithstanding the discrepancy in colour, size and 

 length of the elytra, this is the female of B. princeps, I 

 do not give it a name, though it is quite possible it may 

 prove to be the female, not of B. princeps, but of another 

 species closely allied thereto.
