can be referred to those species (of which I am not certain, not 

 having yet Ohvier or Knoch to consult), but your insect maybe 

 a different one. 



" 220. This singular insect is undoubtedly allied to Mala- 

 chius, and belongs to Latreille's family JKdyrides. From the 

 first and second segment of the abdomen there issue caruncles 

 like those of 209. I believe the wings are never folded under 

 the elytra. I will make this the type of a new genus." 

 This is extracted from my journal ; but since you informed 

 me of the fact that Latreille has observed a tooth in the 

 mandibles of Malthinus, I am inclined to think with you that 

 220 mai/ be referred to that genus. Having only the Regne 

 Animal to acquaint myself with it, I was authorized to sup- 

 pose my insect could not be referred to it, since he placed 

 Malthinus in his Lampi/rides, which are distinguished from the 

 Melyrides by their simple mandibles. But even with the short 

 • account of Mcdthinus in that work, I find room to doubt. He 

 says: '' Dont les palpes sont ter7?imees j^ar une article ovoide.''' 

 The maxillary palpi in 220 have their last joint decidedly secu- 

 riform, though not strongly so ; and the labial ones have their 

 last joint subsecuriform. The outline of Malthinus in Kirby 

 and Spence's first volume, if correct, would prove that my 

 insect differs much from that genus. The antenna?, in that 

 plate, are nearly as long as the body, the thorax differs wholly, 

 and the elytra are made to appear longer than the uncovered 

 portion of the abdomen, Avhereas in my 220 they are constantly 

 shorter, in some only half the length. I shall be glad to know 

 what you think ultimately on the subject, as I mean to abide 

 by your opinion. 



725 is named S. quadrigeminatus Say, in my catalogue, and 

 the following remark is in my journal; "As Mr. Say did not 

 compare insects with this, but most probably only plates or 

 descriptions of S. qimdrimaculatics, maculosus, etc., it is very 

 probable that this insect is S. quadrimaculatus Fabr." 



The Cicindela marked 11 by me, and which you call 0. ah-
