102 THE CANADIAN ENTOMOLOGIST. 



So far, I cannot separate this region, zoologically speaking, from the 

 middle States. Everywhere 1 meet familiar insects, and, although I miss 

 many Northern species and find new ones, I see that I am still collecting 

 in the Atlantic District of the United States. For the present paper 1 

 select the following Lepidoptera from my collections : 



Thecla dolichos ( Attdidcs dolichos, Hubner Zutraege.) Male. 

 The ground color of the wings above is a dead black, but this is nearly 

 entirely overlaid with a most brilliant deep and changeable metallic blue. 

 On the primaries ; the external margin narrowly and apices are ol the 

 ground color as well as an outwardly vaguely defined ovate discal spot.- 

 On the Secondaries, the costal region about the apices is largely and the 

 external margin very narrowly black. There are two tails : The first, 

 obsolete at the extremity of the 2nd m. nervule; the second, long (6 m. m.) 

 and flexile at the end of 3rd m. nervule. Below this, to anal angle, the 

 wing is outwardly produced, and this exserted portion is medially cleft and 

 shows golden powdery scales on paler blue interspaceal black-margined 

 shade spots. Internal margin clothed with long blackish hair. Beneath 

 the wings are dead black. The fore wings show two white dots at base 

 and a median longitudinal metallic blue shade extending over, beyond and 

 about median-nervule : costal edge scarlet at base. Secondaries with two 

 scarlet basal patches ; internal margin shaded with pale metallic blue ; an 

 interrupted pale metallic blue shade line runs along and within the external 

 edge interruptedly from 1st m. nervule to the anal angle : on the exserted 

 portion of the wing this is powdered with golden scales. Inside of this, 

 below 2nd m. nervule, is a very dark red band interrupted by the veins.- — 

 Inside of this a narrow line of golden atoms, very narrowly separated by 

 the ground color of the wing from an inner golden similarly interrupted 

 band, widening on the last interspace. Body above, metallic changeable 

 blue, greenish (as is the base of the primaries) in certain lights, with 

 longer hairs at the base of the thorax. Beneath the abdomen is scarlet, 

 the thorax and legs black with white spots. Head black with a white spot 

 on vertex ; eyes margined with white : palpi black, white at the base.- 

 Base of the head white : the ocular marginations are interrupted, forming- 

 lines on the front and spots behind. Antennae rather stout, gradually 

 swelled, black. Expanse, 42 m. m.
