Coleoptera from Ceylon, 155 



Differs from other small pallid Tachydes iu its more oblono- 

 and less convex form of body and the smaller thorax strongly 

 narrowed towards the base. The eljtra are flattened on the 

 dorsal surface and the three punctured stride on each side of 

 the suture are somewhat sharply impressed with a very faint 

 and short rudiment of a fourth stria. There arc two strongly 

 impressed marginal stria3 on each side. 



Tachys amplians. 



T. globulo (Doj.) proxime affinis et simillimus : ditfert solum colore 

 piillide testaceo striisque paullo distiactius punctulatis vel crenatia. 

 Brevis, coiivexus, flavo-testaceus, antennis (articulis 1-2 exceptis) 

 fusceseentibus ; thorace valde transverse, lateribus versus basia 

 sinuatis, angulis posticis subacutis ; elytris stria suturali Integra 

 striisvque 2-4 valde abbreviatis, parum iucisis, crenulatis, stria 

 marginali uuica, puncto dorsali anteriore deficieiite. 



Long. 2 millim. 



Kandy. 



The elytra appear a little longer and more pointed at apex 

 than in T. globulus. To this small group of Tachysj distin- 

 guished by the disappearance of the submarginal stria (the 

 eighth), of which a few large punctures at the base and apex 

 only remain, belongs also T. perhUus (Bates). 



Tacliys emarginatus.

Putzeys's description (Ann. Mus.Civ. Genova,1875, p. 739) 

 does not agree with Nietner's, nor with the numerous speci- 

 mens taken by Mr. Lewis, as he gives the size as 1\ millim. 

 and states that the elytra have four red spots. The size is 

 2 millim. or a little longer (1 line, Nietner), and the elytra 

 have only two subapical spots. The colour varies from pale 

 testaceous, through castaneous, to bright pitchy black with an 

 aeneous tinge. 



The species occurs in China (at Fu-chau and on the 

 lower Yang-tsze Kiang) as a pale variety, exactly similar to 

 the pale Ceylonese form, except that the lighter subapical 

 spots are not quite so well defined ; this is the insect alluded 

 to as T. scijdmeno'idesj Nietn., in Geod. Col. Japan, Trans. 

 Ent. Soc. 1873, p. 299.
