Zerene calcnnria. — In this species tlic lalcial tlaspcis arc large and lonir. 

 (»val, ol)tusely jjointcd a( tip, with tlie upper edife thickened like the I)ack (if 

 SI back-saw. The siijira-aiial plate; is wys small, hroail, and slmrt ; llic spine 

 Ijroad at i)ase, short and stout: the last segment jiartly covers the armatnre. 



In Acidalia cnudeata the siipra-anal plate is small, solid, triani,ndar; the 

 spiiH' large and double; the lateral claspers are very small, full, and i-omidcd, 

 with a deep sinus on the upper edge. There is akso a pair of laigc. solid 

 black chitiiious hooks, which 1 liav(^ not noticed in tiie prcvioiisly-ni'iilioned 

 genera. 



In (luotcrla Jidiciildfa the last sei,nnent entirely covers the armature ; 

 the lateral claspers are very long, mendiranous, extending far beyoml the rest 

 of the armatnre; the supra-anal plate is very complicated, the end being 

 divid(Ml into two roinided, llat concave portions, from lienealh which projects 

 the broad, incurved triangular spine. 



In .\pl(j(li'S /)ti//ias(ui(i, the armature is covered as usual: tlu^ lateral 

 claspers are very long, subsjiatulate, the u])pcr edge chitinous, tin; chitinous 

 jiortion expanding and bent up al riiijht angles at the end, and ending in a 

 liroad, mueronate point. The su[)ra-anal plate is rather large, scutellale, 

 membranous in the middle, and the spine is very long aiul slender, with the 

 eml blunt. 



In ( 'i/niafopkoia iinihrot!Uii(t, the supra-anal plate is moderalely lari^e, acute, 

 scutellate, ending in a rather sliort spine; the latei'al elas])ers arc; large and 

 long, nu)dei'ately iiroad, spatnlate, the entl curved up a little and incetiiig its 

 fellow on the median line of the l>ody : on the inside, at the bend in the outer 

 edge, is a small bunch of shoit, acute spinules. 



\\\ Endropi I hi/'inc(tr'ni, {\\r hif'eral claspers are lari^e, very broad at the 

 base, somewhat upcurved, the end broad sid)spatulate, a tlee|) sinus on the 

 upper edge, with a long s[)ine projecting inward tVoni the base ot" the up[)er 

 edge. The supra-anal p.late is snudl, trianixular, (le[)resse(l. 



In Caherodes inetrocnmparii, the lateral claspers are moderalely large, 

 broad at the base, the up[)er edge straight, the end rounded, the lower edge 

 bent up a little. It is uiuiiined. The supra-anal |)late is large, broad, 

 triangular, with the median suture very deep. Tlu.' spine is large, and 

 reaches as far as the end of I he lateral claspers.
