Length of posterior wing, ^ 40-41 millim., $ 43-44 

 millim. 



Seven males, four females. 



A very remarkable species and the only one in the genus 

 with the same sharp delimitation of the pale apical portion of 

 the wings ; at first sight it reminds one of a gigantic Euphoea 

 rather than a Cahpteryx. The female has a vague resem- 

 blance to C. Cornelia, and in its elongate and comparatively 

 narrow wings the species may be compared with C. Cornelia 

 and C. atrata, both Chinese and Japanese forms. All the 

 examples before me are mature. 



C. grandceva, Hag., described in 1853, remains known 

 only by the probably immature female type. There are many 

 points in the description opposed to identity with C. Oherthiiri 

 (notably the absence of a pterostigma). 



Archineura incarnata, Karsch. 



Echo incarnata, Karsch, Berl. ent. Zeit. xxxvi. \9Q\, = Archineura 

 basilactea, W. F. Kirby, Ana. & Mag. Nat. Hist., January 1B94 

 (very immature). 



One male of this magnificent insect. 



I marvel that Dr. Karsch did not draw any comparison with 

 the American genus Hetctrina in the way of coloration, the 

 carmine-red at the base of the wings existing only in that 

 genus (with the allied Lais pudica) and in the species now 

 under consideration ; but of course it is only analogy. I am 

 convinced that (as noticed by Karsch, Ent. Nachr. Heft vi. 

 1894) the type of A. basilactea is only an extremely imma- 

 ture example of the same species, and I am of opinion that 

 the locality (Foo-Chow) given for it is erroneous, although 

 it may have been brought to that port from the interior. 



There is no connexion with SapJw as indicated by Kirby ; 

 but I doubt if the insect can be retained in Echo (which was 

 unknown to Karsch, save by description). It is not necessary 

 to go into minute details here ; but the long, narrow, and 

 only slightly dilated pterostigma is opjiosed to Echo, and the 

 arrangement of the branches of the ramule, especially in the 

 posterior wings, is consjncuously diiJ'erent. At present I 

 retain Kirby's generic and Karsch's specific name. 



Caliphcea consimilis, sp. n. 



Head above metallic green, passing into blue, with a 

 yellow spot on each side of the labrum and the second joint 

 of antenna* yellow outwardly ; back of head and under mouth- 

 parts black. Thorax above metallic cupreous or green ;
