Remarks
There are several type specimens of species described by Mellié deposited in historical collections of the MHNG and the MNHN. In the MHNG, these types are in the A. Melly collection, who has a surname similar to that of J. Mellié but shall not be confounded. We did not find type material of Xylographus richardi in the Chevrolat collection of MNHN. We located a female specimen from Colombia in the Melly collection of MHNG named as Xylographus richardi. Mellié (1849)[1] mentioned he has examined specimens from both the Chevrolat and the Melly collections, therefore there is a possibility that this single specimen we located in the Melly collection is a syntype, but we cannot assure this. We compared this female with female paralectotypes of Xylographus corpulentus and Xylographus lemoulti and they are exactly the same. Mellié (1849)[1] provided few differences between Xylographus corpulentus and Xylographus richardi, stating that they resemble each other “pour la taille et la forme”, with Xylographus richardi being more punctate. We believe the description of Xylographus richardi was based on a female specimen, because the pronotal surface between punctures is described as being finely rugose. We have observed that it is common in female Xylographus species to have pronotal surface distinctly more rugose than that of males. The type of Xylographus corpulentus was described as being black, while the one of Xylographus richardi was described as reddish. It is a common variation found in Xylographus corpulentus, in which teneral adults may be reddish (pers. obs.). Pic (1916b)[2] mentioned that Xylographus lemoulti differs from Xylographus richardi in the coloration and pronotal shape, again a consequence of the fact that the description of Xylographus richardi was based in a teneral adult female. The type-localities of Xylographus lemoulti and Xylographus richardi are approximately 200 Km apart and both are in the coast of French Guiana.
