Moimtaius of Spain the species appears to be sj^ecially variable : one 

 example from there is of such large size and dark colour as to simulate 

 T. oscillator. An example from the Ionian Islands is of very pale 

 colour, has the pronotal grooves unusually deep and definite, and the 

 punctures of the elytra quite twice the size of those of the English 

 specimens. Another from Smyrna is also highly aberrant; the general 

 form approximates much to T. mauritanicns, and the median interval 

 of the pronotum is on each side joined to the sub-median so that the 

 sub-median groove is interrupted. 



The distribution appears to be from England, south and east to the 

 Mediterranean shores, but I have not seen any from N. Africa or Syria, 

 and am not aware of any records from there or from Scandinavia. 

 G-anglbauer only says " Mediterranean region abundant," and Reitter 

 does not recognise its existence in G-ermauy. Montpellier abundant 

 and variable ; Guadarrama the same ; islands of the Mediterranean, 

 Sicily, Majorca, Malta, Ionian Islands, Sardinia teste G-ene. 



It occurs both in fresh and salt water. Mulsant described it in 

 the 1st edition of his " Paljncornes of France " under the name of 

 H. intermedius, and stated that it is " southern" ; in the 2nd edition 

 he adheres to the name intermedius, and says that it is common in little 

 streams throughout southern France. Gene's description and figure 

 are extremely poor, but probably refer to this species, and they have 

 several years priority to Mulsant. 



Mulsant mentions a black individual found at Fort Queyras by 

 Garret. This would probably be similar to the dark individual I have 

 mentioned above from the Escorial. 



2.—Trichelop7iorus tnauritmiicus sp. n. 



Testaceus, elyt^-is fusco-maculatis, capite thoracisque medio aenescentibiis, 

 subtus plus minusve late nigricans : elytris parum convexis, fortiter sculpturatis, 

 callo intra-humerali bene prominulo, costis bene elevatis, longius setosellis. Long. 

 3f— 5 mm. 



Hah. : Africa bor. 



Closely allied to T. alternans, and mixed therewith in collections. 

 Rather smaller and more oval, the elytra being more pointed behind, 

 the sculpture and setosity more marked, and the pseudepipleura broader. 



The species is easily separated, once it has been recognised, by the 

 greater torsion of the elytra at the shoulders, the lateral margin 

 springing out there with greater abniptness from under the callosity. 

 A specimen in the Laferte collection was named by Mulsant " Elophorus
