A Synoptic Revision of the Tanyirlijncluna?. 



II. — A Synoptic Revision of the Tanjrrliyncliinae (Curcu- 

 lionidse). By GuY A. K. Marshall, F.Z.S. 



In tlie Berliner ent. Zeits. for 1886 (p. 100) tlie late 

 Dr. Faust published a revision of Lacordaire's tribe Tany- 

 rrliyncliides, in which he then included seven genera. In 

 1889 he gave an additional table of the genera allied to 

 Myorrhinns, two of which were described as new (Deutsche 

 ent. Zeits. p. 140). Since that time a considerable number 

 of new forms have been discovered which must be referred 

 to this group, and, as many of these require new genera for 

 their reception, it seems advisable to give a fresh working 

 synopsis of the whole group. This revision has been rendered 

 possible by the kindness of Dr. K. M. Heller, of Dresden, 

 and Prof. Yngve Sjostedt, of Stockliolni, who have been 

 good enough to lend nie many types and co-ty])es from tiieir 

 museums ; and I am also much indebted to Mr. H. E. 

 Andrewes for the loan of co-types of three Indian species 

 described by Faust. 



Before entering into any definition of the group, it may 

 be well to point out that Faust, when dealing with Tany- 

 rrhynchus, always treated T. costirosiris, Boh., and its near 

 allies as the typical forms of the genus. It was for the 

 reception of these very species that, a few years ago, I 

 proposed the genus Strainia (Proc. Zool. Soc. 190-4, i. p. 140), 

 and the validity of tliat genus has been confirmed by an 

 examination of the type of Tanyrrhynchus^ viz. T. strigi- 

 rostris, Sparrm. 



The species of Stramia differ not only from Tanyrrhynchus, 

 but also from all the genera here associated with it, in the 

 structure of the mouth-parts. The peduncle of the submentum 

 is very markedly produced and the mentum itself is quite 

 small, being very little larger than the peduncle, so that the 

 maxilljB and their palpi are entirely exposed when the 

 mandibles are closed. In the Tanyrrhynchinai, as here 

 defined, this condition never occurs. \x\ their case tlic 

 peduncle of the submentum is always small, sometimes very 

 small, while the mentum is large (many times larger than 

 the peduncle) and nearly fills the whole buccal cavity behind 

 the maiuliblcs, when closed; the maxillary palpi are thus 

 entirely hidden (or occasionally their extreme apices may bo 

 seen ju.st projecting beyond the apex of the mentum) and the 

 maxillae themselves are more or less completely hidden, being 

 more exposed at the base the more thepedunele is developed. 

 \\\ addition to these buccal characters, Stramia may be dis-
