NOTES ON SCOLYTIDiE. 

 By W. F. H. Blandford, F.E.S., F.Z.S. 



1 Pityogenes scitus n. sp. 

 This species is new to science : it is very closely allied to the Euro- 

 pean Tomicus (or Pityogenes) chalcogr aphis, from which it can be sepa- 

 rated only by careful comparison, 



Pityogenes.— Bedel. Fanne des coleoptercs du bassin de la Seine. VI, 

 p. 388. A genus formed to contain those species of Tomicus (as 

 limited by Eichhoff, etc) in which the prosternum has no intercoxal 

 process, the anterior tibiae are sublinear, and the apical depression of the 

 Elytra is impunctate. The type is P. chalcographus. 



P. scitus so. nov. Mihi. — Sub-elongatus, nitidus, sub-glaber, nigro- 

 piceus, autennis et pedibus ferrugineis; elytris ferrugineo-testaceis, basi 

 et margine laterali (et apice in maribus sat maturis) infuscatis; thorace 

 ante medium lateraliter coarctato, post medium impresso, antice fortiter 

 exasperato, postice punctis fortibus, sparsisque notato, linea sub-elevata et 

 plaga laterali laevibus; elytris tenuissime striato-punctatis, punctis versus 

 apicem obsoletis, prope suturam prof unde impressis et dentibus tribus in 

 utroque depressionis latere armatis. 



Long.; 1*7 — 2 mm. 



1 This insect was originally sent to the Indian Museum, as attacking the Shored 

 assaniica tree in Sibsagar, Assam (see Volume I, p. 42 of this serial). On Mr. Blandford's 

 noticing", however, that other species of Tomicus and Pityogenes, in the modern limits of 

 these genera, are only to be found in conifers, some small pieces of stick that were ori- 

 ginally forwarded with the insects, were sent to the Royal Botauical Gardens, Sibpore, for 

 further examination. Here they were kindlv looked at by Dr. George King, who found that 

 they do not belong to the Shorect assamica tree, but possibly to Pinus khasya, the sticks, 

 however, not being sufficient for precise identification. The tree therefore that is 

 attacked by Pityogenes scitus Bland., though not definitely ascertained, is no doubt one of 

 the conifers. The figure shows the imago dorsal view, also much enlarged diagrams of the 

 legs and antenna. The actual size of the insect is shown by the hair line.
