 Long. Corp. 11'"; exp. alar, antic. 29'", postic. 27'", 



Hab. Brazil ? In my collection. 



Possibly the female of delicatulics ; but this is only conjecture. 



6. C. SKPULTUS, Walker. (Ascal. sepultus. Walk. Cat. Brit. Mus. 

 Neurop. p. 445.) Antennae alis aequales, fuscse, ad basin pal- 

 lidiores, pilis verticillatis vix instructa; ; clava fusca, ad basin 

 flava. Frons niger, fusco villosus. Thorax fuscus, infra sparse 

 cano-villosus. Pedes pallide testacei; tibiis extus fuscescentibus ; 

 tarsis nigris. Abdomen testaceum, supra fusco-varium. Ala; elon- 

 gatae, subobtusae, vitreae; venis venulisque nigricantibus; pterostig- 

 mate flavo : anticarum margine interiore ante basin leviter exciso, 

 angulo axillari rotundato : posticae anticis pauUo angustiores ; mar- 

 gine interiore ante basin longe exciso, ad basin paullo dilatato. Long. 

 Corp. 11'"; exp, alar, antic. 25'", postic. 22'", 



Hab. Brazil. 



6. C. DissiMiLis, nov. sp. S . Antennae ante medium flexuosaj, sub- 

 geniculata;, piceo-nigrae ; geniculo setis spiniformibus ad articulorum 

 apices intus instructo. Thorax minimus, supra utrinque late fusco- 

 niger, infra plerumque flavidus. Pedes testacei ; tibiis extus, tarsis- 

 que, fuscis, illis pallido-cinctis. Abdomen fuscum, supra basin versus 

 utrinque lineis nigris, rufescenti-marginatis, notatum. Ala; vitrea;, 

 paullo fumoso-tincta; ; venis venulisque nigris ; pterostigmate sordlde 

 flavo : anticarum margine postico in medio valde dilatato, ante et pone 

 medium leviter exciso ; angulo axillari prominente, obtuso : posticse 

 valde angustiores ; margine postico in medio paullo dilatato, ante basin 

 valde exciso. 

 $ . Antennae fere rectae, pilis baud iustructae. Alae vitrei, hand tinctse ; 

 pterostigmate pallidiore, fere albido : anticae postica;que in medio vix 

 dilatatse, ante basin marginis postici leviter excises. Long, corp 

 9-10'"; exp. alar, c? I7h"'. 2 21'". 

 Hab. Amazons (Bates). 



This curious little species is remarkable for the dissimilarity of 

 form in the sexes, as confirmed by the notes made in situ by Mr. 

 Bates. I have seen only one cf , which ia in the Oxford Museum.
