70 A Visit to Damma Island: 



Tenebrionidae. 



DlATBRINM. 



Platydema sodale, sp. n. 



Ovale, convexum, nitidum, flavum; elytris .r-nigra ornatis. 

 Long. 1| lin. 



Head moderately closely and rather strongly punctured. 

 Eyes separated above by a space equal to rather more than 

 the width of the eye. Thorax rather closely and moderately 

 strongly punctured, but the punctures are of unequal size ; 

 a fine smooth median line extends from the base to near the 

 front margin ; there is a slight impression on each side of the 

 base. Elytra with lightly impressed stria? ; the striae closely 

 and very distinctly punctured ; the interstices gently convex, 

 closely and extremely finely punctured ; yellow, with a narrow 

 blackish-brown basal band (not extending beyond the humeral 

 callus), and a broader band across the middle, not quite 

 reaching the margin, slightly emarginate behind in the third 

 interstice; both bands united by black at the suture. Antenna? 

 with the fourth joint scarcely enlarged, the fifth distinctly 

 broader, the following joints transverse. 



Platydema plagiatum, sp. n. 



Ovale, convexum, nitidum, piceo- nigrum ; ore, antennis pedibusque 

 rufo-piceis ; thorace rufo, subtiliter crebre punctulato, basi 

 apiceque infuscato ; elytris evidenter striato-punctatis, fascia sat 

 lata ante medium (in sutura interrupta) apiceque flavo-rufis. 



Long. 2| lin. 



Antennas dilated from the fourth joint. Head finely but 

 distinctly punctured. Eyes large, separated above by a very 

 narrow space. Thorax red, blackish brown at the base and 

 behind the head, very finely and rather closely punctured, 

 the punctuation more distinct at the sides than on the disk, 

 the extreme lateral margin blackish. Elytra black, with 

 distinct lines of punctures, the punctures close together, the 

 dorsal lines fine and not impressed, the lateral ones stronger 

 and impressed ; interstices closely and extremely finely punc- 

 tured, the lateral ones very slightly convex. Each elytron 

 has near the base a transverse rectilinear yellow spot ex- 

 tending from the margin to near the suture ; this spot is only 

 a trifle wider than the black at the base ; the apical spot 

 occupies the greater part of the apex, extending on the 

 margin itself to the first spot and to the sutural stria at the 

 apex, leaving the suture black, the black widening out above.
