232 SPHAERODERArA PARVULA, 



with a small spine ; the first joint of the posterior tarsi longer 

 than the two following joints together ; claws appendiculate. 



Hah. Sumatra or.: Tandjong Morawa, Serdang (Dr. Hagen). 

 — Three specimens. 



Although the short perpendicular grooves , placed at the 

 posterior margin of the thorax, are strange to the genus Spliae- 

 roderma, I have, in the absence of other characters of 

 distinction, placed S. parvula in that genus for the pre- 

 sent. Several closely allied species have been described («S. 

 cyanipennis Jac, apicipennis Baly, apicalis Baly). S. parvula 

 differs from either in the unicolorous flavous antennae, 

 from S. apicalis and 5. apicipennis in the metallic blue co- 

 lour of the elytra and their more closely placed and stronger 

 punctures arranged in rows, the interstices being finely 

 punctured ; from S. cyanipennis , -S. parvula differs in its 

 larger size and the fulvous apices of the elytra, as well 

 as the colour of the antennae. 



Erystus clypeatus, n. sp. 



Broadly ovate , subdepressed , pale testaceous ; terminal 

 joints of the antennae and the breast piceous ; thorax trans- 

 verse , minutely punctured; elytra finely punctate-striate , 

 the lateral margin flattened. — Length P/g line. 



Head broader than long , extremely finely punctured , 

 with an oblique short groove near the inner margin of 

 the eyes; the frontal tubercles elongate, trigonate, divided 

 by a longitudinal groove and bounded behind by a trans- 

 verse groove ; clypeus transversely thickened , narrow ; an- 

 tennae half the length of the body, the four lower joints 

 fulvous, the others black, the third joint rather longer 

 than any of the following joints ; thorax three times broa- 

 der than long , the sides strongly rounded , narrowly mar- 

 gined , the surface scarcely visibly punctured ; elytra widened 

 at the middle , the lateral margin broadly flattened , the 

 surface finely punctate-striate, pale testaceous; legs short, 

 the tibiae widened towards the apices ; all the femora di-
