88 Mr. Martin Jacoby's dpsnipHons of some 



which have their intermediate joints scarcely widened and of 

 equal length. I possess several specimens from the above 

 localities. 



Akcastes sanguinea, n. sp. 



Brigjht reddish ; the antennae, tibife, and tarsi black ; the thorax very 

 minutely punctured ; elytra finely rugose or wrinkled, and very closely 

 punctured. Length, 2^ — 3 lines. 



Elongate and rather convex, bright blood-red ; the head impunctate, 

 with a deep transverse .groove between the eyes, the frontal tubercles strongly 

 raised, nearly contiguous ; palpi piceous ; antennie robust, black, pubescent, 

 the intermediate joints widened; thorax one-half broader than long, the 

 sides roianded at the middle, narrowly margined, the anterior angles oblique, 

 the surface microscopically punctured ; elytra wider than the thorax, the 

 entire surface finely rugose and wrinkled, the interstices very finely and 

 closely punctured ; under side and the femora red ; the tibiae and tarsi black, 

 the posterior tibiae with a long spine ; the first joint of the posterior tarsi 

 half the length of the tibiae. 



Hah. Perak. (Coll. Jacohy.) 



Sermyloides dilaticornis, n. sp. 



Ovate-oblong, fulvous ; elytra black ; thorax impunctate, narrowly 

 transverse ; elytra black, closely, irregularly, but distinctly, piuictured. 



Var. Elytra with the sutural portion more or less fulvous. 



^. Antennae with the third, fourth, and fifth joints broadly dilated. 

 Length, 3 lines. 



Head impunctate, the extreme vertex more or less piceous, lower portion 

 of the face flattened ; palpi incrassate ; antennae extending to about half the 

 length of the elytra, black, the first joint fulvous, slender, the second short, 

 the following three joints broadly dilated, the rest shorter ; thorax short, 

 three times broader than long, the sides nearly straight, the angles not pro- 

 minent, the surface impunctate, fulvous ; scutellum black ; elytra rather 

 strongly, closely, and irregularly punctured ; under side and legs fulvous, the 

 first joint of the posterior tarsi longer than the following three joints together ; 

 claws appendiculate ; anterior coxal cavities closed. 



Hob. Sumatra. 



In general shape and structural characters the present insect 

 agrees with the other two species placed in this genus, but differs 

 entirely in the dilated joints of the antennae in the male, the 

 same organs being, however, simple in the other sex. (Coll. 

 Jacohy) . 



Macrima abdominalis, Jac. 



Of this species, described by me in the * Notes Leyden 

 Mus.' (vol. vi.), I have lately received some specimens obtained 

 at Perak and at Borneo ; those from the former locality seem to 

 agree with the type, some specimens having, however, a narrow 

 flavous stripe surrounding the scutellum, while others have the 

 extreme sutural margin black. The Bornean examples differ, 

 however, from the type in having a longitudinal black sutural 

 and lateral band, extending not quite to the apex. I am unable 

 to detect any other structural differences than those of colour, 

 and it is therefore probable that the type was described from 

 unicolorous fulvous varieties.
