furtiter punctatis ; thorace medio suh-laevigato, ad latern aranulaio. Loncj. rorj>. 

 3-3 i mm., elytr. 2^ mm. 



Distinguished from miibutus by the rather shorter and more convex elytra, 

 which are more strongly punctured ; by the side of the thorax very little set 

 out, with the sculjiture of the disc less, and by the median interval very strongly 

 angulate in the middle extei'ually. The basal piece of the aedeagi^s (fig. 57) is 

 short, scarcely so long as its terminal segment ; the median lobe and the lateral 

 lobes elongate and slender, the latter slightly sinuate externally. 



Hah. : Arabia (Millingen, five specimens iu the Trj collectiou). 



It is interesting to find a species so closely allied to our common 

 European form at so great a distance. H. fruamis has the palpi very 

 much as in mimdus, and also the flanJ:s of the elytra not visible 

 beneath, by which it is distinguished from II. arahicus. 



44. — -Helophorvs hqjponicus Thorns. 



H. lapponicus Thorns, is treated l)y Ganglbauer and Zaitzev as a 

 synonym of the common H. tninufus Fabr. (=^gri»eiis auctt.). I have 

 long entertained doubt as to this, and having now received two speci- 

 mens from Prof. Sahlberg as lapjjonicus Th., I apply the name to the 

 one of these that agrees best with Thomson's and Kuwert's descriptions. 



The individual in question is a different species from H. mitmtus. It is 

 larger and broader, length 4 mm., the thorax is straight in front, strongly 

 granular everywhere, drill greenish-metallic in colour, with pale cupreous 

 grooves ; the yellow lateral margin is well oiitstanding ; the juxta-median 

 groove is narrow and sinuous but not angulate, the sub-external interval qiiite 

 broad. The terminal joint of the maxillary palpus is large, much darkened at 

 the tip ; legs stout. The aedeagus (fig. 58) is on the whole nearest to that of 

 viinutus, but is not very close ; note especially the great difference in size. 



This specimen is from Muouio, Finland. The second example sent 

 by Sahlberg is remarked on vmder H. jenifieiensis. 



45. — Helophorus jeniseiensis Kuwert. 



H. jeniseiensis was characterised by Kuwert in 1866 as a variety 

 of lapponicus Thoms. As usual his judgement cannot be trusted, but 

 I have received from Prof. Sahlberg a specimen bearing a label in 

 Kuwert's handwriting, " lapuonicns Th. va,Y. jeniseiensis Kuw." The 

 individual is a female, It is however, I believe, distinct from laptponi- 

 cus, though probably closely allied. 



The last joint of the maxillary palpiis is elongate, only very slightly darker 

 on the apical part ; the last labial joint is stout, rather short, yellow. The thorax 

 is moderately large, the sculpture of the median intervals consists of ocellated
