1881.] COLEOPTERA OF SOCOTRA. 473 



The fine frontal line in my spades can scarcely be described as a 

 channel ; and there is no fovea on the vertex. 



4. ZOPHOSIS ^auALis, u. sp. 



Statura fere Z. orientalis, Deyr., at minus conve.va, magis paral- 

 lela, ceneo-niffra, parum nitida; thorace creberrime et subti- 

 lissime punctulatos elytris sat crebre subtilissime puncttilatis. 



Long. 3 lin. 



Oblong-ovate, not very convex ; slightly tinted with eeneous. 

 Head convex, densely and very finely punctured ; labrum not very 

 closely but extremely delicately punctured. Thorax evenly convex, 

 deflexed at the sides, finely margined anteriorly, twice as broad as 

 long, arcuately narrov?ed anteriorly, very closely and extremely deli- 

 cately punctured. Elytra as broad as the base of the thorax, nearly 

 straight at the sides, arcuately narrowed at the apex, moderately 

 convex ; the punctuation is extremely fine, but rather more distinct 

 than on the thorax, and decidedly less close ; on the margin, near the 

 apex, some of the punctures are longitudinally asperate ; the epi- 

 pleural line is completely marginal ; the epipleuron has a few sliort 

 longitudinal impressed lines. The antennie are black ; the second 

 and fourth joints are nearly equal, both a trifle shorter than the 

 third. The spurs on the tibite are reddish. The prosternal process 

 is elongate-ovate, moderately broad, finely margined, extremely deli- 

 cately, and not very thiclvly punctulate. 



Some of the specimens have the epistoma separated from the fore- 

 head by a fine sinuous line, ni the middle of which is a shallow fovea ; 

 the epistoma is more strongly punctured ; and the elytra have more 

 asperate punctures along the whole margins. I take these to be 

 merely varieties, as they vary somewhat among themselves. 



This species appears, from M. DeyroUe's monograph, to be nearly 

 allied to Z. elongata, Deyr. (Ann. Soc. Eut. Fr. 18G7, vii. p. 219) ; 

 but that species has evidently much more asperate punctuation on 

 the sides of the elytra, &c. 



.5. HiSTEROMORPHTJS PLICATIPENNIS, U. Sp. (Plate XLIII. fig.l.) 



Niger, nitidus; capite thoraceque lavibus, elytris singulatimlineis 

 quatuor longitudinalibus angulatis imjjressis, interstitiis 2., 3. 

 et 4. bene convexis angulatim flexuosis. 



Long. 4 lin. 



This species is much smaller than //. plicatus, Kz., but has 

 almost precisely the same form. It is at once distinguished by the 

 remarkable plicate elytra. Each elytron has four zigzag strise 

 (besides a portion of a fifth on the side) ; the space between the 

 first and second stria3 is only slightly convex; the three following- 

 interstices are very convex and are zigzag in the same way as the 

 strise, impuuctate ; the apex of the elytra is flattened above, but 

 scarcely reflexed.
