AI;ir expanse : J -' nun. 



Habitat: Departure I'.ay, T.-C, ( C. 11. Voinigj ; Victoria, B.C., (W'. 

 Downcs). 



T\fc in Canadian National Collection, Ottawa; Cotypc, VS. National 

 Museum No. 23502. 



Named in honor of niv friend C. II. ^'oun,L;■, who lias added very many 

 new records of .Microlepidoptera Ironi Canada and whose e.\(iuisitely motinted 

 specimens add charm to any collection. 



'J'his is the tirst record of the (>l_\-phipteryi;id i;'enus H ilarof/ra/^lia Zeller, 

 from North .America, hut rc(jalis W'alsingham descrihed as a Clyphiptcry.v is also 

 referahle to this i;"enus. 



The jL^enus has heen considered tropical, ranjL^int; from India to Atrica 

 and hest represented in Central and vSoulh .\merica ; one species is recorded 

 from japan. The food plant of Ililarot/ra/^lia nu/alis is /'linis sahiiiiaiia and I 

 e.xpect the present species also feeds on conifers. 



HilarugrapJia Zeller. of which the Central and South .\merican H. si^'cd- 

 criana Stoll is the tx'iK'. has the following;- characters. Lahial palpi somewhat 

 flattened, slighth' tufte(l; terminal joint tolerahly pointed, ahout as liMig as 

 second. Forewin^;- hroadU- trians^ular ; 12 veins, all separate, 7 to termcn. 3 

 from hefore the end of the cell, 2 hefore three-fourths of the cell, ih furcate 

 at ba.se. IJindwin^s broader than forewings, triangular rounded, cS veins, 6 

 and 7 stalked, 3 and 4 cf)nnate. 



Male genitalia with 8th segment strongly modified as a covering 

 for the genitalia ])roper ; uncus sharply i)ointed ; aedoeagus long, stout, straight; 

 annulus broadly heartshaped ; vincuhnn narrow. 



Tha gentis Sctiostoiiia Zeller, tv|)e .vanfliobasis Zeller, which was de- 

 scrihed in this faniilv and wliich has hitlu'rlo been placed close to IUhnuxjrapJia 

 Zeller (according to Mevrick actualK- a devt'lopment from it) has no affiliation 

 whatever with this group, but belongs to the fannly Slcuoiiiidac, (not e(jua! 

 .\ yloryclidiic Ale\rick ) constituting a t\pical genus of that lamil\-, amplv dil- 

 ferentiated genericalK- b\- \cin 7 of the forewing to costa. but otherwise with 

 ever\- characteristic of that famil\-. lis wing foi'ni and oi-namenlation indicate 

 that it is probablv de\'eloped from forms similar to SIciidiiui lad is llusck and 

 Stoioiiia orioii I'.usck. 



From the venation and oral characters alone Sctiostonia may be mis- 

 taken for Cilyphipterygid, as indeed it has Ix'cn all along, though careful study 

 of these characters also clearh- shows its true relations, but the genitalia give 

 these at once and without doubt. 



The genitalia of Srtiostoiiia are t\])ical vStenomid in every respect and 

 very dilTerent from anything in the (ityf^hl/^trrvj/idac. The evidence of the 

 genitalia is so clear cut and conclusive that there can be no doubt about the 

 position of the genus. It is one of the ver\- many instances, where the value 

 of the genitalia as an aid in the svstematic work bec(jmes ai)parent to anyone, 

 who will look into the subject even sui)erliciallv.
