The distribution of M. aeqnalis appeal's to be much the same as 

 that of aquaticus, and the form seems to be quite as common. As I 

 have already said, at BroL'lcenhurst the two live in the most intimate 

 association, and yet they are in nearly all cases easily distinguished. 

 This, however, cannot be the same in all localities, for a collection of 

 72 specimens made in Epping Forest by Mr. C. J. C. Pool proves to 

 consist of 71 aquaticus, with very little variation, and 1 aequalis. 



3. — Meghelopliorus manchuricus sp. n. 



Capite pronotoque viridis, hoc sulcis cupreo-auratis,parumprofundis, antennis, 

 palpis (?), pedih^is elytrisque testaceis, his paulidum iiigro-maculatis ; suhtus 

 nigricans, ahdomine rufo-variegato. Long. 5|, lat. 2j mm. 



Extremely close to M. aequalis, especially to var. splendevs, but 

 with the sides of the thorax less sinuate and the front margin straighter, 

 and distinguished by the brilliant metallic colour of the head and 

 thorax. The sculpture of the latter granular, but very shallow, sub- 

 effaced. The elytra are yellowish, with vague fuscescent areas, with a 

 few black marks across the middle. The under-surface black, with the 

 sides and hind-margins of the ventral segments reddish. Legs very 

 slender. I have seen only one example (probably a female), slightly 

 immature and bereft of its maxillary palpi. 



Manchuria (Adams, from the Fry collection). 



4. — MeghelopJiortis frigidus, Grraells. 



This is closely allied to the small dark examples of M. aeqtialis I 

 have mentioned as occurring in the Tyrol, but it is always distinguished 

 by the greater smoothness of the median intervals of the thorax ; in 

 the smaller examples there is only a feeble punctuation on the middle 

 of this interval, in the largest there is a very effaced granulation. The 

 interstices of the elytra are flat, and their pubescence very minute. 

 The length varies from 4-5^ mm. The lateral and median lobes 

 of the aedeagus are shorter in proportion to the basal piece than they 

 are in aequalis, the median lobe being especially short and broad. 

 Grraells' description and figure being very poor, this species has been 

 quite misunderstood. Seidlitz thought that frigidus Gr. was the 

 southern M. milleri, whereas it is a sub-alpine form. Kuwert believed 

 it to be the same as aequalis (having apparently seen no example) . Bedel
