ruginous. The posterior margin of the protliorax angulated ; 

 wings slightly fuscous ; the knees, tibia, and tarsi reddish 

 yellow. Abdomen subsessile, smooth, and shining; the two 

 apical segments with a few long, erect, black hairs. 



Hab. Chili (Coquimbo). 



In the collection of the British Museum there is a single 

 example of this insect, and three of the typical species (C. 

 Kingii., Haliday) — two from the Straits of Magellan, and one 

 from Bahia Blanca, North Patagonia, Argentine Confederation. 



Genus Mygnimia, Shuck. 

 This genus was proposed by Shuckard in Lardner's ' Ency- 

 clopaedia,' published in 1840 ; he gave the name, and pointed 

 out sufficient characters for the discrimination of the species. 

 In 1855 I gave fuller generic distinctions 5 inconsequence, 

 some authors adopt the genus as being mine ; others adopt 

 the generic name proposed by Dahlbom, namely Heniipepsis^ 

 which appeared in 1845. The name proposed by Shuckard 

 must take precedence, it having the priority of date. 



Mygnimia helUcosa. 



Male. Length 15 lines. Black; the antennae, clypeus, la- 

 brum, palpi, mandibles, tibise, and tarsi ferruginous ; wings 

 dark fuscous at their base and apex. The clypeus tnincate 

 anteriorly ; the mandibles black at their apex ; the scape of 

 the antennae black above. The pro- and metathorax with thin 

 short black pubescence ; the metathorax truncate, the margin 

 of the truncation elevated, with a transverse shallow striation 

 above, and an abbreviated impressed longitudinal line in the 

 middle at the base ; wings tjlack at their base, becoming 

 lighter at the base of the first discoidal cell, from thence it is 

 flavo-hyaline, the apical margins of the wings having a nar- 

 row fuscous border ; the nenan-es are pale ferruginous in the 

 subhyaline portion of the wings, and black in the darker part. 

 Abdomen Avith the base shining, beyond opaque. 



Hah. Bengal. 



Mygnimia scevissima. 



Female. Length 9-12 lines. Black; head, legs, anterior 

 part of the thorax, and two apical segments of the abdomen 

 ferruginous ; the ferruginous parts have a line short bright 

 golden or fulvous pubescence. The mesothorax at the sides 

 and beneath, and the metathorax entirely, black ; the latter is 

 usually more or less tinged with ferruginous above at the 

 base, truncate at the apex, and transversely irregularly stri-
