i Kenlober kunde paa de friskt indfangede Exemplarer hverken 

 Spor af Pigment eller lysbrydende Medier bemærkes. 



Iste Par Følere (Fig. 5) udspringer vidt adskilte fra 

 Bovedets forreste Sidehjørner umiddelbart foran Øienloberne 

 og er lige udstrakte omtrent af Hovedkjoldets Længde. De 

 bes*taar, som dos Slægten Apseudes, af et 31eddet Skatt og 

 2 Svøber. Skattets Iste Led er meget stort, indtagende 

 mere end Halvparten af Følernes Længde, pladeformigt, 

 noget udvidet mod Enden og i den ydre buede Kant for- 

 synet med 4 stærke Børster. 2det Led, der tilligemed 

 den ovrige Del af Føleren danner med Basalleddet en 

 vinkelibrmig Bøining udåd, er neppe mere end '/ 3 saa langt 

 og simpelt cylindriskt samt ved Endeii i liver Kant forsynet 

 med nogle lange Borster. 3die Led endelig er særdeles 

 lidet. omtrent ligesaa bredt som langt og uden tydelige 

 Borster. Svøberne er af ulige Længde og ved Basis for- 

 bundne med binauden. Den ydre er længst og sammensat 

 af 4 Led. hvoraf de 2 midterste hvert foruden en simpel 

 Børste bærer i den forreste Kant et finalt Igjennemsigtigt 

 Sandsvedhæng eller saakaldt Lugtepapille: dens sidste Led 

 ender med et Knippe af simple Børster. Den indre Svøbe 

 er neppe mere end halvt saa lang som den ydre og bestaar 

 af 3 med simple Borster besatte Led. 



Met Par Folere (Fig. 6) udspringer ligeledes vidt ad- 

 skilte lige under Iste Par (se Fig. 3) og er omtrent af 

 samme Længde som disse, men meget spinklere. Man kau 

 paa dem adskille et 4-leddet Skaft og en enkelt kort Svøbe. 

 Skaftets Iste Led er ganske kort. men forholdsvis bredt, 

 noget udvidet mod Enden eller næsten omvendt hjerteformigt. 

 2det Led er smalt og cylindriskt; 3die særdeles lidet og 

 rudimentært; 4de derimod meget langt og smalt samt for- 

 synet i begge Kanter med flere af de eiendommelige pensel- 

 formige saakaldte Horebørster. Svoben, der omtrent er af 

 samme Længde som Skaftets sidste Led, bestaar af 4 Led. 

 hvoraf de 3 yderste er forsynede med nogle simple Haarbørster. 

 Det for Slægten Apseudes characteristiske bladformige Ved- 

 bæng til disse Folere mangler her ganske og aldeles. 



Imellem Følernes Insertion og Munddelene tindes et 

 temmelig betydeligt. noget concaveret Mellemrum. der danner 

 Epistomet. hvilket fortil umiddelbart fortsætter sig i Pande- 

 pladen (se Fig. 3). 



( hntrent i Midteu af Hovedsegmentets nedre Flade 

 sees (Fig. 3) en noget hjelmformig Forhoining, der danner 

 Basis for Overlæben. Denne har Formen af en afrundet 

 firkantet Lap. der ender med en i Midten svagt indbugtet 

 skarp Kant (se Fig 7 og 9). 



Underlæben (Fig. 8) er temmelig stor. pladeformig og 

 bestaar af 2 sy metriske, i Midten saminenvoxede Lapper. 

 Til det ydre Hjørne af hver Lap er fæstet et lidet be- 

 vægeligt indadrettet Led af konisk Form og besat med Hne 

 Borster. 



witbin the small ocular lobes. in the recently tåken speci- 

 mens, neither traces of pigment nor any visual elements 

 whatsoever could be detected. 



The Ist pair of antennæ (fig. 5) spring, widely apart, 

 from the foremost lateral corners of the head. immediately 

 anteriorto the ocular lobes. and. fully extended. aliout equal 

 the cephalic shield in length. They consist, as in the genus 

 Apseudes. of a three-jointed peduncle and 2 tlagella. The 

 Ist joint of the peduncle is very large, measuring more 

 than half the length of the antennæ. lamelliform. somewhat 

 dilated towards the extremity. and on the outer arcuate 

 margin armed with 4 strong bristles. The 2nd joint, which, 

 together with the remaining portion of the antenna, bends 

 outward. forming with the basal joint a distinct angle, is 

 scarcely more than one-third as long, and simple-cylindric, 

 as also. at the extremity. on eitber side furnished with a, 

 few long bristles. Finally. the 3rd joint is exceedingly 

 small, about as long as broad, and without distinctly de- 

 veloped bristles. The tlagella are unequal in length and 

 at the base connected together. The outer flagellum is 

 longest, and composed of 4 joints, of which the 2 median 

 have each. exclusive of a simple bristle on the anterior 

 margin, also a narrow. translucent sensory appendix, or. as 

 it is termed, olfactory papilla ; its last joint terminates in a 

 fascicle of simple bristles. The inner flagellum is scarcely 

 more than half as long as the miter, and consists of 3 joints, 

 beset with simple bristles. 



The 2nd pair of antenna' (fig. 6) take their origin, 

 likewise widely apart, just under the Ist pair (see fig. 3), 

 and are about of the same length. but much more slender. 

 On these antennæ can be distinguished a four-jointed peduncle 

 and a single, short flagellum. The tirst joint of the peduncle 

 is quite short. Out comparatively broad. somewhat expanded 

 towards the end. or almost inverted - cordiform ; the 2nd 

 joint is slender and cylindric: the 3rd exceedingly small 

 and rudimentarv. the 4th. on the other hand. verv long 

 and slender. as also furnished on both margins with several 

 of the peculiar scopiform. so-called auditorv. bristles. The 

 flagellum . about of the same length as the last joint of the 

 peduncle. consists of 4 articulations. of which the 3 outer- 

 most are provided with a few simple bristles. The squami- 

 forrn appendix to these antennæ characteristic of the genus 

 Apseudes is entirely wanting. 



Between the points of insertion tor the antennæ and 

 the oral appendages. occurs a comparatively extensive, some- 

 what concave space. forming the epistome. which, anteriorly, 

 protends straight into the frontal plate (see fig. 3). 



About in the middle of the lower surface of the cephalic 

 segment, is seen (fig. 3) a somewhat galeate prominence, 

 that forms the base of the labrum. The latter has the form 

 of a rounded quadrate lobe. terminating in the middle with 

 a faintly incurved sharp margin (see figs. 7 and 9). 



The labium (fig. 8) is comparatively large, lamelliform. 

 and consists of 2 symmetrical lobes, connate in the middle. 

 To the outer corner of each lobe. is attached a small niov- 

 able, inward-directed joint, of conical form. and beset with 

 delicate bristles.
