140. Rhembus laevigatus, n. sp. 



R. polito affinis et similis, sed certe differt thoracis angulis 

 obtusis (apice rotundatis). Caput laeve (absque rugulis), labro 

 et epistomate similiter emarginatis. Thorax laevior, linea dor- 

 sali minus impressa. Elytrorum striae minutissime punctulatae, 

 interstitio angusto 9.°" cum margine fere laevi nitido, nee sicut 

 in affmibus ruguloso opaco. Subtus fere laevis, lateribus haud 

 coriaceo - rugulosis , sed sericeo - nitentibus. — Long. 15 mil- 

 lim. c/'. 



Kawkareet in Tenasserim. One example only.

Palon (Pegu). 



The only Eastern species hitherto described in which the 

 scutellar striole is wanting, as in the North American Rhemhi 

 and in R. Aegyptiacus. The small head gives it a distinctive 

 facies. Dejean gives the length as 9 y^ ^i^^s (circa 21 millim.). 

 The single specimen from Palon measures 19 millim. and I 

 have examined a c/' from Assam which reaches the same length 

 as that of Dejean. 



142. Rhembus colossus, n. sp. 



R. impresso proxime affinis sed multo major, palpis apice late 

 truncatis etc. Elongatus, elytris lateribus sat rotundatis, niger 

 nitidus, minutissime discrete punctulatus. Caput relative parvum, 

 foveis frontalibus latis, elongatis, vagis; epistomate apice medio- 

 criter et late arcuato-emarginato ; labro parum profunde et 

 triangulariter emarginato. Palpi articulo apicali ( 9 ) maxillaribus 

 rectilineo apiceque recte truncato, labiahbus fortiter dilatato 

 (haud compresso) apice truncato. Antennae comparate breves. Ely- 

 tra oblongo-ovata, convexa, striata (striis haud distincte punctu- 

 latis) interstitiis paullulum convexis. Thorax quam in R. impresso 

 brevier, panilo transversus, elytris multo angustior, panilo ante 

 medium leviter rotundatus ante medium curvatim, post medium 

 sinuatim et minus, angustatus, angulis posticis subrectis sed
