entirely yellow except au iufuscatiou of the apical part of the terminal 

 segment of the tarsus. The upper surface bears an abundance of 

 short curved setae. The grooves of the thorax are deep, the external 

 one more definite than usual ; the intervals are roughly granulate and 

 setose, the median one extends quite to front margin, where it is a 

 little broader and flatter ; it is only a little broader in the middle, and 

 not angularly prominent externally, so that the sub-median groove is 

 not very irregular ; the sub-median interval is rather narrow behind 

 but considerably broader in front, so that its inner edge is sinuous, it 

 does not reach to the front margin ; the sub-external groove is well 

 marked. The sculpture of the elytra is coarse, the costae strongly 

 raised, and there is a slight transverse depression a little in front of 

 the middle that gives rise to a slight irregularity there of the elevated 

 second interstice. 



Considerable variation occurs, especially as to colour. In a few 

 the thorax is a good deal infuscated, and the elytra are more extensively 

 maculate, and the sterna and base of the abdomen are also infuscate. 

 In some cases the depression on the elytra is more marked. 



Empleurus nnhilns is widely distributed in the British Islands, 

 and is no doubt common over much of Western Europe. French 

 specimens from as far south as Lyons agree with the ordinary form 

 found here. Mulsant says " common in Trance, but I have not seen, 

 any from the Mediterranean zone." In the Fry collection there is, 

 however, an old and bad example labelled " Nice." Common in 

 Germany, according to Reitter, and according to Ganglbauer over 

 the greater part of Europe. Kuwert says " Northern and Central 

 Europe," but he gives a var. costatus as to which cf . E. hispanicus. 



2. — Emjpleurus hispanicus sp. n. 



E. nubili proxime affinis ; colore obscuriore, statiira magis depressa, siilcis 

 prothoi'acis minvis argutis, aedeago longiore, etc., distinctiis. Long. 3^ — 4 mm. 



Extremely close to E. nubiliis, but with the after-body more elongate and 

 depressed and the colour not so pale as in the type form of nubilus, though 

 somewhat similar to the dark var. There is considerable variation analogous 

 to that of nubilus, but I have not seen an example that really agrees with any 

 specimen of that species. 



The aedeagus is larger and more elongate than that of tiubilus with a 

 longer median lobe, and the apices of the lateral lobes not quite so widely 

 separated. We have mounted the structures of the two side by side, and I 

 hope to have them photographed and illustrated. 



Found by me in the Asturias and Gruadarrama. I have not seen 

 any other examples.
