80 (Ap'ii. 



small, sharply sulcate down the middle anteriorly ; antennae long, slender, 

 joints 7-11 flattened, and very broadly, obliquely dilated, 3 elongate, as long as 

 4 and 5 united. Prothorax more than twice as broad as long, rounded at the 

 sides anteriorly, the hind-angles rectangular, the base sinuate, the basal foveae 

 rather deep. Scutellum very large. Elytra moderately long, broad, very much 

 wider than the prothorax, sub-parallel in their basal third, compressed at the 

 sides behind the tumid humeri. Beneath closely, finely, the metasternum very 

 sparsely, punctate ; prosternal process rather broad, abruptly declivous behind. 

 Length 9, breadth 5 mm. 



Hah.: ? Indo-China {ex coll. Bowring). 



One specimen, acquired in 1871. Easily recognised by tiie very 

 broad, flattened, 5- jointed antennal club, the metallic-blue upper 

 surface, and the large, ochreo-pubescent, cupreous scutellum. P. ohli- 

 quata F. has a similarly clothed scutellum. 



Syncheoina. 

 Synchroa Newman. 

 Synchroina Fairmaire, Ann. Soc. Ent., Fr., 1898, p. 399. 

 The type of the genus Synchroina, 8. tenuipennis, Fairm., from 

 Sumatra and Perak, differs from the N. American Synchroa punctata 

 Newm., and the very closely allied S. melanotoides Lewis, from Japan, 

 in having the raised anterior portion of the mesosternum horizontal 

 and more deeply sulcate for the reception of the prosternal process ; but 

 these characters are insufficient for generic separation, the mesosternal 

 sulcus being quite obvious in Synchroa. Fairmaire was doubtless un- 

 aware that two species of Synchroa had been recorded from Japan in 

 1895. A fossil from the Colorado Miocene was described by Wickham 

 (in 1911) under the name S. quiescens. 



1. — Synchroa cuneata, n. sp. 



Elongate, narroAV, fusiform, shining, thickly clothed with long, decumbent, 

 fulvous hairs ; fusco-castaneous, the elytra with a broad, common, attenuate 

 sutural stripe, and the antennae, femora, and tibiae, piceous. Head short, 

 strongly transverse, closely punctate ; antennae slender, not half the length of 

 the body. Prothorax transverse, arcuately narrowed anteriorly, bisinuate at 

 the base, completely margined at the sides ; rather coarsely punctate, the punc- 

 tuation finer and more diffuse on the disc, the basal foveae deep. Elytra not 

 wider than the prothorax, moderately elongate, rapidly narrowed from a little 

 below the base, rather sparsely, confusedly, aciculato-punctate, the punctures 

 moderately coarse at the base, becoming much finer towards the apex, the sutural 

 stria deeply impressed along the apical third. Beneath coarsely, closely, the 

 ventral surface finely, punctate. Mesosternal process horizontal, deepl}?^ sulcate 

 anteriorly for the reception of the prosternal piece. Length 8, breadth 2 ^ mm.
