^ Fitijogenes scitus n. sp. 



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

 pean Tuviicus (or Fiti/ogenes) chalcogr aphis, from which it can be sepa- 

 rated only by careful comparison. 



Pityogenes. — Bedel. Fauna des coleoplercs du bassin de la Seine. VI, 

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

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

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

 Elytra is in)punctate. The type is F. ckalcographns. 



F. scivus sp. nov. Mihi. — Sub-elongatus, nitidus, sub-glaber, nigro= 

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

 et margine laterali (et a^^ice in maribus sat maturis) infuscatis; thorace 

 ante medium lateraliter coarctato, post medium impresso, antice fortiter 

 exasi^erato, postice punctis fortibus, sparsisque notato, linea sub-elevata et 

 plagakterali laevibus; elytris tenuissime striato-punctatis, punctis versus 

 apieem obsoletis, prope suturam profunde impressis et dentibus tribus in 

 utroque depressionis latere armatis. 

 Long, j 1*7 — 2 mm. 



1 This insecb was originally sent to the ludian Museum, as attacking the Shores 

 rasMMizcatreeinSibsagar, Assam (see Volume I, p. 42 of this serial). On Mr. Blandford's 

 noticing-, liowever, that other species of Tomicus and Fityogenes, in the modern limits of 

 these-geneia, 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 Botanical Gardens, Sibpore, for 

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

 they do not belong to the Shorea. assamica tree, but possibly to Finns hhasya, the sticks, 

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

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

 the conifers. 'J"he 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.
