EROTYLIDAE FROM BURMA "28^^ 



^'2. Petaloscelis instabilis, n. sp. 



Oblongo-ovala, flava fere aurantiaca; macula hand bene discreta, 

 occipitali, duabiis prothoracis transversis, una basali, altera frontali 

 saepe obliterata, elytrisque nigris, his signatura communi litteram x 

 referente ad basim annexa, flava; antennis ficscis. Long, b-6.5 millim. 



Variat prothorace fere nigro, flavo-variegato , elijtris, signatura 

 fere obsoleta, vel fere tota flava elytris apice m versus infnscatis, pro- 

 thorace tantum maciUis basali et apicali; saltello vel flavo vel piceo. 



Hab. Burma, Garin Gheba. 



This insect is very variable in size and colour , but the pat- 

 tern can generally be made out, the variation ))eing due simply 

 to the greater or less diffusion of the black pigment. The punc- 

 tuation of the head and thorax is excessively fine, close and even^ 

 the elytra are punctate-sti-iate , similar to .1. cinctipennis. The 

 striae lightly impressed , the interstices flat and with a very 

 fine and close punctuation. The underside is yellow , in dark 

 examples it is (as are the legs) apt to become a little infuscate. 



Of P. instabilis nine specimens are before me , five of these 

 present the form \^'ith an x- like yellow mark on the base of 

 the elytra, common to both, two are of the varietj^ with the 

 thorax black with yellow marks, and two have the yellow co- 

 lour diffused on the elytra, and as is often the case in .1. cincti- 

 pennis, not always evenly on the two elytra, indicating imma- 

 turity.

1 place the following species in Cyrtomorphus, as it is hardly 

 advisable to multiply genera, but they do not altogether accord 

 with the type (C. panther inus) , and I shall accordingly note 

 under each species, the form, granulation of the eyes, abdominal 

 lines, and elytral sculpture; characters wliich have been em- 

 ployed for casting the genera of this section. 



A. Body short, gibbous.
