HYPHASOMA. 



171 



Head with vertex impunctate, frontal elevations broad, nearly 

 contiguous, carina strongly raised, convex. Antenna? extending 

 to about the middle of the elytra, covered with line hairs ; first 

 segment elongate, club-shaped, second small, shorter than either 

 first or third, the latter shorter than the former, fourth slightly 

 longer than third ; from the fifth to the end the segments are 

 almost equal. Prothorax much broader than long, sides rounded, 

 lateral margins somewhat explanate and reflexed, anterior angles 

 obliquely thickened; upper surface almost impunctate, but under 

 a high power and in a suitable light some very fine punctures are 

 visible. Elytra somewhat broader at the base than the prothorax 

 finely and confusedly punctate. 



Length, 4 mm.

I am uncertain of the whereabouts of the type of H. parvula : 

 that of H. few is in the Genoa Museum. There is a co-type of 

 H. few and another specimen bearing Pea's locality label in the 

 British Museum. An example from the Mentawei Islands 

 {Modigliani) is also in the British Museum. I have compared a 

 co-tvpe of H. parimla with a co-type of H. fern and am of opinion 

 that they are the same species, and that it has a very wide 

 distribution in Assam, Burma and the Malay Archipelago.

Broadly rouuded-ovate. Colour yellow-brown; antenna? (the 

 three basal segments excepted), scutellum and breast, piceous. 



Head with vertex impunctate, frontal elevations transverse, 

 quadrate, contiguous, separated from the vertex by a deep 

 transverse impression, and carina strongly raised. Antenna? more 

 than three-fourths the length of the body, slender; first segment 

 elongate, club-shaped, second small, shorter than either first or 

 third, the latter shorter than the fourth ; the following segments 

 are almost equal, except the eighth, ninth and tenth, which are 

 somewhat shorter. Prothorax about three times as broad as long, 

 sides broadly margined, edges reflexed, nearly straight and parallel 

 behind the middle, rounded and converging in front, front 

 angles ending in an obtuse, outwardly curved point, hind angles 

 distinct, subacute ; upper surface impressed with minute punc- 

 tures, the interspaces still more minutely punctate. Scutellum 

 triangular with apex rounded and surface impunctate. Elytra 

 broader at base than prothorax and broadening much more 

 behind, distinctly and rather closely punctate, with lateral margins 

 broadly dilated and only slightly reflexed. Underside : prosternum 

 narrowly oblong, slightly sinuate at the sides, with apex obtuse 

 and surface only slightly excavated ; posterior tibia? unarmed at
