It is well known by the yellow colour of the scutellum and 

 of the underside of the prothorax and ventral plates, by the 

 purple spot on the disc of the pronotum and by the distinctly 

 punctured surface of the latter >. The discal spot is nar- 

 rower than that on North African examples (Nefich) belong- 

 ing to the same variety in my cabinet The antennal stern- 

 ite is quite entirely yellow, not or very slowly infuscated 

 near the median spot of the head, so that the yellow colour 

 of the sides of the prefront reaches the eyes and that the 

 antenno-frontal suture is drawn through it. Nothing of the 

 specula or goggles discovered by D. Sharp on the underside 

 of the labrum in the tf of several European species of Laccobius 

 is to be detected on leucaspis.

Three specimens captured in a small pool at the edge of 

 Lake and one at that of a small spring on the shore three miles 

 north of Tiberias belong to this chiefly mediterranean beetle. 

 The antennal sternite of this species is dark on the whole and 

 the little yellow lateral spot on the prefront is placed immedi- 

 ately before the antenno-frontal suture. No specula seem to 

 be present under the labrum of the <? of gracilis. 



Laccobius (s. str.) sp. 



A single Laccobius from W. es Semakh, closely allied to 

 gracilis, Mots., is not sufficient in itself to identify the species 

 accurately. It seems therefore better to leave it undeter- 

 mined for the present, the more as it is represented only by a 

 2 specimen. From gracilis it may at once be distinguished 

 by the finer and sparser punctuation of the head, faintly 

 indicated metopico-sagittal suture and distinctly alutaceous 

 interspaces. The pronotum is also much more feebly punctu- 

 ated and very obscurely alutaceous under a good microscope; 

 the discal spot instead of being transverse is rounded, being 

 only a little broader than long and triangularly emarginated 



J The specimens at hand are blackish here and there, but this is due 

 to the manner wherein the beetles were mounted on card.
