also considered aeqvalis and frigidns as synonymous, and the latter 

 name haviui> priority be adopted it for the combination ; frlgidus and 

 aequalis are, however, more different than aqvaticns and aeqvalis. 



M. frigidvs occurs in profusion at a considera])le elevation in the 

 G-uadarrama range, and Champion has found it also in the neighbour- 

 ing Sierra de Bejar and at Tragacete. 



5.^ — Meghelophorus milJeri, Kuwert. 



Although this is treated by G-anglbauer and Zaitzev as a sub- 

 species of aquaHcus, there can be no doubt as to its being a distinct 

 species. Of the size of aqnaticns, it is distinguished by the deeper 

 grooves of the thorax, and the diminished granulation of the median 

 intervals, as well as by a greater development of the setosity of the 

 upper surface, and numerous minor and more variable distinctions. It 

 appears to be a Mediterranean insect extending from Montpellier and 

 Marocco to Syria, and foiuid also in Mesopotamia and Arabia. 



Being somewhat variable in colour, and in the setosity of the 

 elytra, several races have been supposed to exist, but I cannot perceive 

 anything more than variation, a little exaggerated possibly, as to 

 certain points in some localities. 



The thorax is usually bright in colour, and is a little less strongly 

 transverse than it is in aqvaficus. Its yellow colour laterally extends 

 along the front margin, the sub-external interval is separated from the 

 lateral margin, so that there is an external groove, and the same 

 interval is much interrupted in the middle, so as to be nearly divided 

 into two parts. The colour is very variable, and in some localities the 

 elytra are usually very pale. The villosity of the elytra is often worn 

 off, but then the fine punctuation from which it arises is visible and 

 sufficiently different from that of aqiiatictis. There is no constant 

 difference in the aedeagus, though the lateral lobes are usvially a little 

 longer in miller i. 



Montpellier, Malaga, Marocco and Algeria, Sardinia, Corsica, 

 Sicily, Malta, Corfu, Grreece, Smyrna, Syria, Mesopotamia and Jeddah, 

 are localities from which I have examples before me.
