Genus LXIX. — Auctia * Schrank. 



Paljii porrected, short, very hairy, triarticulate, the basal joint longer than the 

 second, tlie terminal ovate, or cylindric : rnaxiUu; short. Aniennoj rather long, 

 slender, bipectinated in the males, serrated in the females, the serrations and 

 pectinations terminated by a fine bristle : head small, pilose : thurax stout, 

 densely pilose : abdomen robust, tufted at the apex in both sexes, transversely 

 streaked or spotted: loings deflexed, densely scaly, elongate -trigonate: legs 

 short, femora very pilose : anterior tibice vsrith a compressed lobe. Larvcs 

 solitary, cylindric, thickly clothed with elongate fascicles of hair, each fascicle 

 arising from a tubercle ; when touched roll themselves into a ring: pujm rather 

 elongate, with a spine at the apex, enclosed in a loose extended web ; eggs 

 naked, deposited with regularity. 



Tlie lively and brilliant colours of tlie Arctite offer a splendid 

 contrast to the sober and chaste hues of most of the foregoing g<inera 

 of Arctiidpe, of which family this genus appears to be the type. 

 From the preceding and following genera this may be known by 

 the robustness of its thorax and abdomen, and by the latter being 

 transversely stnped or longitudinally spotted: the basal joint of the 

 palpi longer than the second, and the antenuEe rather elongated. 

 The species hereunder given appear to differ considerably from each 

 other ; but as they will not associate with any other genus, and I 

 have not an opportunity of being acquainted with- their habits, &c., 

 it must be understood that they are merely placed In this genus 

 provisionally, as being apparently their best location.

A highly beautiful insect: antennae with the shaft white, the ratlii fuscous: 

 head and thorax fuscous, the latter v/ith a narrow ring anteriorly, and the 

 apex posteriorly red : anterior wings fuscous, with numerous white irregu- 

 larly waved strigte: cilia brown, except at the anal angle, where they arc 

 white: posterior wings red, with the cilia flavcscent, sometimes speckled with

* In restoring the name Arctia to this genus, I have adhered to the rule, which 

 is with justice generally adopted, of employing that which has the claim of 

 priority. Why Ochsenhcimcr should have rejected the term so aptly given by 

 Sclirank, I am at a loss to determine.
