Astathes and allied Genera of Longicom Coleoptera. 57 



be distinguished by its relatively narrow form. In general 

 form it is more like the species of the next section ; but 

 from the structure of its prothorax I consider it to be more 

 nearly allied to the species placed in the present section. 



SECTION V. 



Centro-dorsal tubercle of prothorax small and narrow, not pro- 

 longed in front to interrupt the anterior transverse groove, the latter 

 being continued in a straight line right across the pronotura ; dorso- 

 lateral tubercles not sharply edged behind. Elytra each with two 

 distinct dorsal costae in addition to the sutural costa. Last ventral 

 segment of the female not foveate. The species of this section are, as 

 a rule, smaller, and relatively narrower than those of the preceding 

 sections. 



32. Astathes straminea. 



Astathes straminea, Pasc, Trans. Ent. Soc. Lond., (2) iv, p. 

 108 (1857). 

 Head and prothorax black ; elytra entirely yellowish-testaceous ; 

 underside almost wholly pitchy-black ; femora and tibiae more or 

 less piceous ; antennae pale testaceous with the basal joints more or 

 less brown. Head distinctly and rather closely punctured in front, 

 less closely on the vertex ; pronotum closely punctured at the sides 

 of the central tubercle and in the groove in front of and behind it. 

 Elytra feebly punctured. 



Hob. Burma. Type in Brit, Mus. 



The type specimen appears to be slightly immature, 

 the legs antennse and elytra being paler than in other 

 specimens, and the centro-dorsal tubercle of the prothorax 

 slightly testaceous instead of black. 



33. Astathes bipartita. 



Astathes bipartita, Thorns., Syst. Ceramb., p. 558 (1865). 

 Astathes pulchella, Pasc, Trans. Ent. Soc. Lond., (3) iii, p. 

 354 (1867). 



Keddish-testaceous or fulvous ; with the basal half of the elytra 

 violaceous-blue, the apical half yellowish, the metasternum at the 

 sides, and the last three or four joints of the antennae dark brown. 

 Head densely punctured in front. Pronotum less closely but more 

 strongly punctured, except on the central and lateral tubercles which 

 are somewhat smooth and glossy. Elytra sparsely and rather feebly 

 punctured, each with two distinct dorsal costae in addition to the one 

 alongside the suture.
