joints testaceous beneatli ; the head obsoletely, the pro- 

 thorax somewhat closely, punctulate, the elytra shagreened 

 and rugulosely punctulate. Head (PI. XIV. fig. 28) nar- 

 rower than the prothorax, with an oblique, deep, angulate 

 groove on each side between the eyes above^ the two grooves 

 transversely coalescent on the vertex, and each limited 

 behind by a tuberculiform plica, the central space raised, 

 triangular, and truncate posteriorly; antennse very elon- 

 gate, rather stout, sharply serrate. Prothorax transverse, 

 obliquely narrowed posterioily; deeply foveate, binodose, 

 and produced in the middle in front, the anterior margin 

 triangularly raised in the centre. Elytra broader than the 

 prothorax, rapidly widening posteriorly. Legs slender, 

 hairy ; anterior tarsal joints 1 and 2 thickened, 2 extending

 Road, alt. 6000-8500 ft. (;S'. A. Neave : ii. 1911). 



One male. Near H. humatipygus ( c? ), the antenna very 

 long and sharply serrate, the prothoracic tuft replaced by 

 a triangular elevation of the anterior margin, the legs black, 

 the head testaceous above. 



The Abyssinian Attains grandis, Ab. (type $ ?), is very 

 like the present insect, but it is larger and has longer elytra. 

 The $ cephalic structure is somewhat similar to that of 

 H. simoni, Ab., and H. acanthopygus. 



33. Hedybius acanthopygus, sp. n, 



? . Moderately elongate, slightly widened posteriorly, 

 shining, thickly clothed with whitish or pallid pubescence 

 intermixed on the elytra with long, erect, bristl'y hairs ; testa- 

 ceous, the eyes, antennae (the basal joints in part excepted), 

 scutellum, and tip of pygidium black, the elytra and meta- 

 sternum blue or bluish-green; the head and prothorax 

 obsoletely punctulate, the elytra densely, very finely sub- 

 rugulosely punctured. Head narrower than the prothorax, 

 flattened; antennse short, serrate, rather slender. Pro- 

 thorax transverse, rounded at the sides. Elytra moderately 

 long. 



$ . Antennse longer and stouter, the basal five or six 

 joints usually testaceous ; head (PL XIV. fig. 29) shining 

 and flavescent anteriorly, subopaque at the base, with a deep,
