larva under the name DyscriHna, being unable to place it, owing to the extra- 

 ordinary caurial HCfrmented set«^, which have since been explained by 

 Mr. Green's observations. 



Mr. Green's work upon the life-history and development of the two 

 Ceylonese species has since become historic, and should be consulted by 

 everybody iuterested in the subject,

DIPLA TYS GERST^CKERI (Dohrn.)*» 



Colour reddish-testaceous, varied with brown. Head te taceous, sometimes 

 darker anteriorly ; eyes prominent, black. Pronotum reddish, sometimes 

 varied with brown. Elytra red, with an occasional brownish pa ch in the 

 centre. Wings witb the scale reddish, brownish on the outer border. Abdo- 

 men dirker-reddish, shining. Feet testaceous : the tubercles of the second 

 and third segments are small and difficult to discinguish. Branches of the 

 forceps stout, simple. 



Long, corporis 10* 5-l4"75mm. 



„ forcipis =. l-l"25mm. 



This species varies is colour from a uniform bright-red to a dull-brown 

 in colour ; the elytra may be plain-red or dull-brown. The whole body is 

 pubescent.

* As to the identity of Nannopyyia gevsUecken, Dohrn, and Diplati/ Icgisetosa, W'-stw., I 

 am indebifd to Heir Dr Mobius, Director of the Koni 1, Museum fiir Ndtaurkune of Berlin 

 for the following notes, made by Herr Dr. Kuhlgaiz, of the same muspum. Dc-hrn's lypp of 

 Nannopygia ^er«trec/{ert is in the Berlin o;>llection. '' Diplatys lonffisetosa, Westw , is ve-y 

 cloBely allied to this species, but not actually iden'ical with it. ^annc/'ygia gerstceckeii 

 is entirely bronze-coloured with black eyes ; in Diplatys longiseOisa the head is black. The 

 forceps increas' a little more in thickness from the apex t - tt'O has than in Nanno/jygia 

 gerstcsckeri. T^e elytra nf the latter are uniform in colour and broader ihan in D. longise- 

 tosa, in which on the two posterior third of the elytra there is a long blackish shadow streak 

 (at least in the two specime' s in the Berlin Museutu), B"h forms prob bly bel6ng to 

 one and be same g' nus (?). In structure they scarcely differ at all.' 



From tl'is it wiU appear that I was perfectlj justified in rejecting Di hr- 's genus 

 JVa«n"/)»/^!0)as idepitical with the earlier Di/ilatys, but apparet.tly 'he two s ecies are 

 dis'inct, though very clo-ely aQied : it is possi le that t ey may i e dimurp ic f^jrms if one 

 Bpecies, " hich i doubtless mo e r 1 ss v riab e in size and colour 



De Bor ans set arates them by the form ■ f the last abdominal i-egtiient, wh'ch is S( uare 

 in Diplatys &aA ^czxQ \y i.>r not aX ull produced in ISannoi ygia\ in the form r the bead is 

 narrower behind, the sec nd tarsal segment is broader in the latter. I still prefer to regard 

 the two as one genus making A", gcrstceclceri identical with D. longisetosa and moving
