CLASSIFICATION OF THE ASCALAPHIDiE. 



251 



4. C. integer, nov. sp. Antennae alis longiores, flavidae, ad articulo- 

 rum apices nigra?, basin versus pilis verticillatis paucis instructae ; 

 clava fusca, obscure pallidiore annulata. Frons fuscus, fusco-villosus. 

 Thorax fuscus, supra flavo-raaculatus, infra cano villosus. Pedes 

 fusci femorum dimidio basali flavo ; tarsis nigricantibus. Abdomen 

 fuscum, supra utrinque lineis nigris, ochraceo-marginatis, signatum. 

 Alae elongate, subobtusae, vitreae ; venis venulisque nigris ; pterostig- 

 mate nigro-fusco, nigro-venato : posticarum margine interiore ante 

 basin recto, haud exciso, angulo axillari obtuso : posticarum mar- 

 gine interiore basin versus leviter exciso, ad basin vix dilatato. ( ? ) 

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



Hab. Brazil? In my collection. 



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



5. C. sepultus, Walker. (Ascal. sepultus, Walk. Cat. Brit. Mus. 

 Neurop. p. 445.) Antennas alis aequales, fuscae, ad basin pal- 

 lidiores, pilis verticillatis vix instructae ; 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. Alae elon- 

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

 mate flavo : anticarum margine interiore ante basin leviter exciso, 

 angulo axillari rotundato : posticae anticis paullo 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. . Antennae ante medium flexuosae, sub- 

 geniculatae, piceo-nigrae ; geniculo setis spiniformibus ad articulorum 

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

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

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

 utrinque lineis nigris, rufescenti-marginatis, notatum. Alae vitreae, 

 paullo fumoso-tinctae ; venis venulisque nigris ; pterostigmate sordide 

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

 medium leviter exciso ; angulo axillari prominente, obtuso : posticae 

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

 valde exciso. 



2 • Antennae fere rectae, pilis haud instructae. Alae vitreae, haud tinctae ; 

 pterostigmate pallidiore, fere albido : anticae posticaeque in medio vix 

 dilatatae, ante basin marginis postici leviter excisae. Long. corp. 

 9-10'"; exp. alar, o* 17*"', 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 cT, which is in the Oxford Museum.
