GRAPTA VI. 



In Grapta Interrogationis there are also found three celhilar spots, but dif- 

 ferent in shape and position from those before mentioned; one being sub-rhom- 

 boidal, depending from subcostal and running obliquely back to a point on a 

 central line from base; just below this spot and a little anterior, and separated, 

 starting from the central line, is another spot of nearly same shape that extends to 

 median, the two forming a broken line; near base, running with the central line is 

 the third spot, small, long oval. In J album, which should be classed with the 

 Graptas, very much such an arrangement of the three sjiots occurs as in Interroga- 

 tionis, but the two outer spots are connected at their angles on the central line, and 

 the smaller one is much enlarged. In the true Vanessans there are also three cel- 

 lular spots, but more widely differing still from those of the small Graptas. In 

 Antiopa the lower spot is turned obliquely to the upper, the position of this last and 

 the basal spot being much as in Interrogationis. In M'dberi'ii the two outer s2)ots 

 are large and confluent forming a broad zigzag band across cell; the third spot 

 does not run with the central line but crosses it obliquely from its origin on median 

 near base. In Californica the arrangement is much as in Milbcrt'ii. Such features 

 illustrate affinities, and also show how a genus becomes broken into groups with 

 a tendency to further division. 



ZepJigrns was taken abundantly by Mr. Mead, during the mouth of August 

 1871, in Colorado, and was found throughout the State wherever collections were 

 made, frequently in company with a small specii's allied to Faunus, to which I 

 have given the name of ILjIai^, and of Vanessa Antiopa. Mr. Mead writes, "On 

 the 28tli, on South Park road, in the mountains about twenty miles from the Park, 

 I found a large, smooth rock, exjsosed to the sun, on which were several Grajitas, 

 Zephyrus and a species nund>ered three {Ilglan). On this rock and in immediate 

 vicinity I captured twenty Zephyrus and five of the other. I had jjreviously, on the 

 16th, found both species together in the vicinity of Berthoud's Pass, where fifteen 

 of the smaller one were taken with a few Zephyrus, on a small patch of flowers 

 high lip the mountain. These were the only oc^casions on which the small Grapta 

 (Ilylas) was seen." I have also received Zephyrus from Nevada, and from Fort 

 Simpson, Mackenzies River.
