1892.] COLEOPTERA FROM KIN A BALU. 87 



anticis infra medimn dente acuto valde distante armatis ; hand 

 compresso-sinuatis. 



Hub. Borneo, Kina Balu {Whitehead). 



Antenuse longer than in E. marginatus, all the joints from the third, 

 and the club, being longer. The thorax is not so broad, especially 

 at the base, the hind angles in the male not being nearly so much 

 produced, but still they are acute ; its disk is more uneven, there 

 being in the single male before me an impressed pit on each side 

 of the centre ; the elytra have the expanded margin more gradually 

 widened, so that it is narrower at the shoulders than in E. mar- 

 ginatus. The four spots are larger in proportion, and placed nearer 

 together than in that species, and they are more acuminate at the 

 apex, and the middle of their disk is much more acutely raised, the 

 summit of this raised part being conical and nearer the two anterior 

 spots than the corresponding part in E. marginatus. The front 

 tibiae in the male are nearly straight, not strongly sinuous nor dis- 

 torted as in E. marginatus, but a little compressed laterally with a 

 short external groove at their apices (for the reception of the tarsi), 

 but not grooved along their whole length. 



This insect has also some analogy with E. turritus ; but the larger 

 yellow spots and the dark bkie colour of the elytra, as well as the 

 structure of the tibiae, will at once distinguish it. 



One specimen, a male, obtained by Mr. Whitehead. 



EUMORPHUS COSTATUS. 



Eumorplius costatus, Gorham, Endom. Rec. p. 34. 



Mas, tibiis anticis dente acuto valde distante in medio armatis ; 

 tibiis intermediis et posticis mediocriter curvatis, his intus 

 ciliatis. 



I believe a single male and female from Kina Balu to be identical 

 with the species described by myself from two female specimens 

 from Celebes. The male has the elytra shining, and with an indis- 

 tinct violet tint, while the female is siibopaque and is distinguished 

 by a short keel on the elytra at their base near the scutellum. The 

 yellow spots are large, and cause the species to recall E. quadrinotatus . 

 The male has the hind angles of the thorax acutely produced, by 

 which it is at once separated from E. quadrinotatus. 



EuMORPHUS GUERINI. 



Eumorphus guerini, Gorham, Endom. Rec. p. 33. 



Many specimens of this were obtained by Mr. Whitehead ; all 

 1 have yet seen are males. Hitherto only seen from the Malay 

 peninsula. 



Eumorphus LTJCiDUS, n. sp. (Plate IV. fig. 1.) 

 Nigro-subviolaceus, niiidus; elytrisovatis, apice acuminatis, maculis 



duobus rotundatis aurantiacis nitidis, anteriore parum tumida ; 



thorace (femincB) subopaco. Long. 9 millim. 5 . 

 Eab. Borneo, Kina Balu {Whitehead). 

 It is difficult to compare this species with any other of the genus ;
