ioo R. W. CROSSKEY 



The following summary shows the main characteristics of Linnaemya (including 

 Palpina and Xanthoerigone). 



Eyes densely haired. Parafacials bare or at most finely haired on upper part. Epistome 

 moderately to very strongly prominent, visible in profile. One pair of strong reclinate orbital 

 setae (often crossing at their apices, sometimes preceded by a pair of rather strong slightly 

 reclinate frontal setae that simulate orbitals). Second aristal segment at least twice as long 

 as broad, usually more. Palpi very reduced, not more than half as long as third antennal 

 segment, usually shorter than second antennal segment and sometimes papilliform; if longer 

 than second antennal segment then filiform and usually with one or two very long apical hairs. 

 Propleuron, prosternum and prosternal membrane bare. Humeral callus with four or five 

 strong setae of which three stand in a straight (or almost so) basal line. 3 + 3 dc setae. Three 

 post ia setae. Three stpl setae (exceptionally only two). Pteropleural seta rather weak (tip 

 not surpassing apex of upper calypter) to moderately strong or very strong (at its strongest 

 reaching back to a level with the apex of the lower calypter). Scutellum with four or five 

 pairs of marginal setae (including crossed horizontal apical setae and either one or two pairs 

 of laterals). Mid tibia with at least two ad setae and usually with a submedian v seta (this 

 seta reduced to a small setula or absent in some males). Hind tibia usually with a strong 

 pv apical seta, sometimes with very small inconspicuous pv not clearly differentiated. Vein 

 i?! almost always bare (setulose on basal or median part in some forms) ; setulae on vein 7? 4+5 

 confined to basal node or at most extending only as far as r-m. Bend of vein M strongly 

 angulate, with a long well developed M 2 appendix or at least a short dark M 2 fold. Cell i? 5 

 open. Second costal sector bare ventrally (very rarely with a few scattered setulae). Basicosta 

 pale yellow. Abdominal Ti + 2 excavate to hind margin. Sternites at least slightly exposed. 

 Suture between T4 and T5 often partially or almost wholly obliterated. 



Lepidoptera provide the hosts for members of the Linnaemyini, especially the 

 Noctuidae, but almost nothing is known of the hosts in the Oriental Region. L. 

 vulpinoides has been reared from an unidentified noctuid in Malaya. 



Key to Oriental Species of LINNAEMYA Robineau-Desvoidy 



[Note. Most Oriental species are known from very little material and it is not necessarily 

 certain that all names cited are valid. The key is merely a preliminary attempt to segregate 

 the species on external features: male genitalia have not been studied. L. paralongipalpis 

 Chao and L. rohdendorfi Chao from southern China have not been seen and are omitted.] 



1 Wing vein i? x bare ........... 2 



- Wing vein R 1 setulose on its middle section. Undescribed sp. (near montshadskyi Zimin) 



2 Wings tricolorous, creamy white at the base, extensively dark brown medially, and 



hyaline apically. Upper occiput with a regular row of strong black occipital setae 

 behind the postocular row. Scutellum creamy white and sharply contrasting in 

 colour with the mesonotum and abdomen which are shining black to naked eye. 

 Fore tarsi of $ dorsoventrally flattened, very broadly and conspicuously dilated 



Undescribed sp. (near speciosissima Mesnil) 



- Wings not so, more or less uniformly hyaline. Upper occiput either without dark 



vestiture behind the postocular row or with inconspicuous and irregular black hairs 

 or weak setulae. Scutellum not creamy white, usually dark yellowish to brownish 

 and not, to the naked eye, strikingly contrasting in colour with the mesonotum or 

 abdomen. Fore tarsi not flattened and dilated or at most only slightly and 

 inconspicuously so .......... . 3 



3 Scutellum with one pair of lateral setae ........ 4 



- Scutellum with two pairs of lateral setae (but not equally strong) . . . 17
