On two new and some already known Longicorns, belonging to the Batoceridae
In the Trans. ent. Soc. IV (1845) p. 86 Mr. Parry gives a very short diagnosis of his Batocera Calanus, a description so incomplete that it is impossible to find out which of the Batocera-species with eight elytral spots is meant. — In the Catalogue of Messrs. Gemminger and von Harold B. Calanus is placed as a synonym of B. Roylei Hope. As I visited last summer the British Museum, I found there among the Batocera’s a species labelled B. Calanus Parry, quite distinct from B. Roylei Hope, but with the aid of Parry’s description I could not ascertain whether that determination was correct or not. — Happily Mr. B. W. Janson informed me that Mr. A. Fry was the possessor of Parry’s Longicorns and as I visited that gentleman he kindly allowed me to take Parry’s type specimens with me for comparison. — B. Calanus differs so largely inter alia by the absence of the spine at the scape of the antennae and the much smaller and otherwise shaped spots on the thorax and elytra) from B. Roylei that it will not be necessary to give an ample description of the differences, the more so because it is so closely allied to an other species, viz. B. guttata v. Vollenh. (Fabricii Thoms., vide Ritsema’s synonymical remark in »Notes from the Leyden Museum” III (1881) p. 10) from Java and Sumatra. — I think it even probable that having large series of both the species, the intermediate forms to unite them may be found. — For the present it will be useful to point out that B. Calanus differs in having a general narrower shape, the basal portion of the elytra covered with smaller granules, the scutellum more triangular, the elytral spots larger, suboval in a longitudinal direction. — (Plate 1, fig. 2 and 3, shows a female of each of equal size).
