genera and species of Malacoderm Coleoptera. 403 



characteristic is that there are three nearly equal and 

 squarish pits in front, while behind there are two lateral 

 ones opening into a very short central groove. The 

 excavated production of the head in front is very 

 remarkable. P. nasutus differs from P. minutus in its 

 more sordid yellow colour; in the thorax not being black 

 but pitchy, with yellow ridges and margins ; and in the 

 coarser sculpture of the elytra, which are also not 

 clothed with minute scales. The antennae in P. minutus 

 have the apex yellow ; this is not the case here. 



Conderis, Waterhouse [111. Typ. Col. B. M., p. 59.] 



The genus Conderis, as proposed by Mr. Waterhouse 

 for Calopteron signicolle, Kirsch., has the thorax with 

 four areolets, and a central diamond-shaped groove, and 

 the antennas simply serrate, but with the apical joints 

 diminishing in width, in the degree of serration, and 

 obliquely truncate at their apices. To this type he has 

 united a species from India, C. major, Waterh., and I 

 have described a third, C. miniatus, from Sumatra 

 ('Notes from the Leyden Museum,' iv., p. 98, 1882). 

 The central channel, groove, or fossa increases in dimen- 

 sions in some nearly-allied genera, which should, I 

 think, all be placed in the subfamily Erotides, till it 

 forms an open lozenge- or diamond-shaped areolet, 

 whose angles reach the front and hind margins and 

 sides, or nearly so (Taphes, Pyropterus). The two 

 species now described are typical Conderides, having a 

 small central pit, formed as it were by the divided carina 

 on the disk of the thorax, and united laterally with the 

 side margin by a transverse ridge, running a little back, 

 and faintly sinuous. 



Conderis orientis, n. s. 



Ater, opacus, thoracis carinulis et marginibus parum 

 nitidis, elytris striga humerali, sutura, margine, et costis 

 pube purpureo micantibus, antennis maris corporis fere

The rufous appearance of the margins, suture, 

 shoulder-stripe, and costae is owing to a velvety pile,
