knipper, der tjener til at bevæge den ovrige frie 

 Del af Føleren. 2det Led, der ialmindeliglied er 

 rettet lige fortil. dannende med Iste en mere eller 

 mindre t^uleligt udpræget albuformig Boining, er 

 omtrent saa langt som de 2 følgende tilsamnien og 

 noget forstykket paa Midten, næsten tendannet. Det 

 bærer i Midten af den ovre Kant en enkelt stærk 

 Fjærbørste og i den nedre Kant, nærmere Enden, 

 en Rad af omkring 8 saadanne, der hurtigt aftager 

 i Længde udåd; ved Spidsen af Leddet findes des- 

 ^^den et Knippe af divergerende simple Børster. 3die 

 Led, der sædvanlig med det foregaaende danner en 

 meget stærk, retvinkJet knæformig Bøining, er noget 

 indknebet ved Basis, men iidvides suceessivt mod 

 Enden, der er skjævt afskaaret i Retningen forfra 

 bagtil. Det har i hver Kant, nær Enden, en Rad 

 at cilierede Børster, hvoraf de i Bagkauteu er længst. 

 4:de Led er meget kort og bredt, næsten triangulært 

 ug ligesom foregaaende skjævt afskaaret i Enden, 

 men i modsat Retning, hvorved dets Bagkant bliver 

 meget kort. Forkanten er bevæbnet med en Rad af 

 korte Torner og ender med et noget sammentrykt, 

 kort triangulæx"t Fremspring, der ved Spidsen bærer 

 en noget ste ne Torn'). At de 2 terminale Vedhæng 

 har det forreste Formen af en oval Plade, omtrent 

 af samme Længde som Skaftets 3die Led, og langs 

 Yderkanten og Spidsen tæt besat med fine haar- 

 formige Børster ordnede i to Rader. Det bagre 

 Vedhæng, der repræsenterer den egentlige Svobe, er 

 omtrent af Skaftets Længde og afsuialnes suceessivt 

 mod Enden. Den bestaar af omtrent 15 Led, hvoraf 

 dog de 3 første ikke er tydeligt sondrede fra hin- 

 anden. Hvert Led bærer ved Enden i Forkanten et 

 Knippe 'af smaa Børster, hvoraf nogle har Charac- 

 teren af Sandsevedhæng (Lugtepapiller), og i Bag- 

 kanten en enkelt simpel Børste. Hos den endnu 

 ikke slægtsmodent udviklede Han (Fig. 1) ligner 

 disse Følere temmelig samme hos Hunnen, alene med 

 den Forskjel, at Svøben er mere opsvulmet ved 

 Basis og delt i et noget større Antal Led. 



De nedre Følere (Fig. 1, a-. Fig. (!), som ud- 

 springer tæt bag de ovre, mangler ganske det blad- 

 formige Vedhæng, men er forovrigt hyggede efter 

 samme T3^pe som hine og har ligeledes Skaftet dob- 

 belt geniculeret. Iste Led er, som paa de evre, 

 meget fast forbundet med Hovedet, stærkt musculost 



') Hos Sl. Paramhalia er dette Fremspring betydelig større 

 og grovt sagtakket i Forkanten. 



fig. 7, a'), without trace of any setaceous armature, 

 and filled with strong muscular bundles, which serve 

 to move the remaining free part of the antenna. 

 The 2nd joint — which is usuallj^ directed straight 

 forward, forming with the 1st a more or less dis- 

 tinctly marked elbow-shaped bend — is about as 

 long as the 2 succeeding ones together and some- 

 what tumefied at the middle, almost fusiform. It 

 carries in the middle of the upper edge a single 

 strong, plumose bristle, and on the lower edge, 

 nearer the extremity, a series of about 8 similar 

 bristles that rapidly diminish in length outwards: 

 at the tip of the joint there is, further, observed 

 a bundle of divergent simple bristles. The 3rd joint, 

 which with the pi-eceding one usually forms a very 

 strong right-angled geniculate bend, is somewhat con- 

 stricted at the base but gradually expands towards 

 the extremity, which is obliquely truncated in a direc- 

 tion from before backwards. It has on each edge, 

 near the extremity, a series of ciliated bristles, of 

 which those on the posterior edge are the longest. The 

 4th joint is very short and broad, almost triangular, 

 and like the preceding one obliquely truncated at the 

 extremity but in tlie opposite direction, causing its 

 posterior edge to be very short. The anterior edge 

 is armed with a series of short spines and termin- 

 nates in a somewhat compressed short triangular 

 prominence, which at tlie point carries a somewhat 

 largish spine ') Of the two terminal appendages 

 the foremost one has the form of an oval lamella, 

 about the same length as the 3rd joint of the pe- 

 duncle, and along the outer edge and at the point 

 it is closely beset with delicate capilliform bristles 

 arranged in two series. The posterior appendage, 

 which represents the flagellum proper, is about 

 same length as the peduncle and tapers gradually 

 towards the extremity. It consists of about 15 joints, 

 of which, however, the 3 first ones are not distinctly 

 separated from each other, llach joint carries at 

 the extremity, on the anterior margin, a bundle of 

 small bristles, of which some have the nature of 

 sensor}^ appendages (olfactory papillæ), and on the 

 posterior edge a single simple bristle. In the still 

 incompletely sexually developed male (fig. 1) these 

 antennæ resemble prett}^ much those of the female, 

 with the sole difference, that the flagellum is more 

 tumefied at the base and divided into a somewhat 

 larger niimber of joints. 



The inferior antennæ (fig. 1 a-, fig. 6) which issue 

 close behind the superior ones, are completely without 

 the foliaceous appendage, but are constructed, other- 

 wise, according to the same tj'pe as those, and have 

 also the peduncle doubly geuiculated. The 1st joint 

 is, as in the superior ones, very .firmly united to 



') In the gen. Paranehalia, this prominence is considerably 

 larger and coarsely serrated on the anterior edge-
