27G Mr. F. P. Pascoe on new Genera 



posticeque bisulcato, utrinque fortiter dentato, antice in medio 

 tuberculis duobus iiitidis subapproximatis instructo ; scutello sub- 

 orbiciilari ; elytris remote puctulatis, in medio depressis, fascia 

 indeterminata albida iiotatis, singulis tuberculis quatuor, tribus 

 basalibus, uuo antemedio, pone medium parte elevata literam X 

 (lambda) simulante signatis ; corpore infra pedibusqiie griseo- 

 pnbescentibus, his satnratiore anniilatis ; tibiis anticis intus baud 

 dcntatis; tarsis anticis, art. ultimo excepto, subnigris. Long. 

 6 lin. 



Hah. Sierra Leone (Sherbro' Island). 



The absence of the tooth on the inner edge of the anterior 

 tibige, and tlie presence of a horn in front, as in Prosopocera^ 

 seem to indicate tliat this species shouki scarcely be referred 

 to Ancylonotus. For the present, however, I am content to 

 consider it a somewhat aberrant species of the genus. My 

 specimen is a male ; but, from a note, I see that the female 

 has much shorter anteunaj, although the third joint bears the 

 same relative proportion to the two following. 



Distema Mastersii. 



T>. saturate cinnamomea, vix nitida, lineis maculisque fulvis e pube 

 adpressa efFectis ; capite utrinque lineis duabus verticalibus, una 

 ante, altera pone oculum sitis ; antennis tenuibus, infra vago 

 ciliatis ; prothorace valde transverso, disco baud tuberculato, lineis 

 transversis ornato ; scutello semicirculari, densius pubescente ; 

 elytris cuneiformibus, singulis bicostulatis, basi bituberculatis, 

 apicibus bispinosis, spina exteriore longiore, in medio punctis nudis 

 plurimis notatis, maculis plus miuusve contiguis oruatis ; corpore 

 infra nitido, lateribus fulvo maculatis. Long. 4|-5| lin. 



Hah. Queensland (Wide Bay). 



This species, with D. j)umila and I>. cuneata^ seem to be 

 intermediate between Zygocera and Disterna, having the nar- 

 rower prosternum of the former, but with its anterior portion 

 abru]3tly vertical and a little excavated as in the latter ; yet 

 Lacordaire places them in different groups. Zygocera was 

 originally characterized by Erichson (Wiegm. Arch. 1842, 

 p. 224) ; but as it was in German, and after the Latin descrip- 

 tion of Z. canosa, it has been generally overlooked. Dr. Ho witt 

 informs me that the latter is identical with the species T sub- 

 sequently described under the name of Z. luguhris. The type 

 of Distema, J. Thoms., is Z. hifasciata, Pasc, erroneously 

 printed ^^inji.iscata^'' in the ' Systema Cerambycidarum ' (p. 88). 

 I owe my specimens of the well-marked species described 

 above to Mr. Masters, to whom I dedicate it.
