148 EROTYLIDAE. 



PseudotritOTna p u l c h r a , n, sp, 



Fere hemisphaerica , rufo-picea, nitidissima ; prothoracis 

 disco utrinque et lateribus indistincte infuscatis, elytris 

 laete rufis , punctato-striatis , humero piceo , puncto com- 

 muni suturali in medio , trienteque apicali obliquiter nigris. 

 Pedibus rufis. Antennis ad apicem infuscatis. — Long. vix 

 4 millim. 



Hab. Sumatra: Moeara Laboe, one specimen (Scient. 

 Sumatra-Expedition). 



This pretty little beetle is very evenly round , the tho- 

 rax being as wide at its base as the elytra, and the head 

 deeply received ; both are thickly and finely punctured , 

 the former more distinctly so than the head. The elytra 

 are evenly punctate-striate , in this differing from P. ni- 

 grocruciata Crotch , in which they are rather strongly 

 punctured all over with very little indication of series ; the 

 interstices in P. pulchra have however numerous minute 

 points. 



The pattern of the elytra is singular, and probably va- 

 ries. In our single specimen the black central spot is round 

 and well defined , the apical black portion is somewhat 

 indefinite, and shades off into a livid yellow at the apex, 

 it extends across the apical third of the elytra obliquely 

 to near the middle of the margin. Underneath the body 

 is rufous with the middle of the breast pitchy. 



Phoxogenys^ n-g- 



Corpus breviter ovatum , convexum. Palpi maxillares 

 articulo ultimo lunato hand perlato; mentum triangulare, 

 antennae tenues breves , clava brevi , debili. Prosternum 

 latum, antice subcompressum , postice truncatum vix 

 emarginatum , valde punctatum , processu intercoxali mar- 

 ginato, lineis baud antice productis. Mesosternum trans- 

 versale , punctatum. Metasternum lineis obliquis tenui- 

 bus utrinque impressis , episterna vix attingentibus.
