the series of 31. Palla does not exist here and the female is sometimes quite like 

 the male. Sometimes the ground color alternates transversely with a slightly 

 diluted tint, and for the female this character would be sufficient. But both 

 sexes differ in the constant absence of the eye-spots of the submarginal band. 

 I received this species from the headwaters of the Tuolumne Kiver where it 

 was collected during the stay of the State Geological Survey in the elevated and 

 uninhabited regions. I take this opportunity of showing my respect for Prof. 

 Whitney and the other members of that learned party, to all of whom I am 

 under obligations for the kindness with which, under all kinds of hardships, 

 they collected materials for a Fauna of our Californian Lepidoptera. 



3. 31. Gabbii, Behr, n. sp. 



Alae maris supra ut in 31. Palla, feminae fasciis transversis alternantibus luteis 

 et fulvis totae nigro clathratae. 



Alae inferiores ut in 31. Palla, sed maculae radicales candidae pruinaque 

 argentea renitentes ita ut fascia intermedia lunulaeque marginales. Fasciae, 

 maculae, et margo aurantiacae ordinariae. Fasciae submarginalis spatium, quae 

 non occupatur lunulis aurautiacis, sulphureum. 



I received this species from the mountains near Los Angeles and have seen a 

 series of specimens constantly showing the same characters. This description 

 I made from a pair kindly communicated to me by Mr. Lorquiu. 



4. 31. Hoffmanni, Behr, n. sp. 



Alae et maris et feminae a radice usque ad medium nigrae hinc et illinc 

 maculis luteis fulvisque obsitae, a media ala luteae marginem versus fulves- 

 centes plus minus nigro clathratae. 



Alae inferiores subtus ut in 31. Palla, sed fascia submarginalis inter lineas 

 undulatas nigras, non lunulis sed punctis omnino rotundis constituta. 



This species is less rare than the two preceding. Nevertheless it has not 

 yet been found near San Francisco and seems peculiar to the higher regions of 

 California. 



Melit^a, Type III. 



Of this type, we know already as many Californian as European species, 

 but except 31. Phaeton, I do not know any Eastern representative of this 

 type. The most robust and gaily colored species belong to this type and 

 it is one of the most predominant of the diurnal types in California, not only 

 from the number of its species but also of its individuals. 

 1. 31elitaa Chakedon, Doubleday. 



This showy species is very common around the Bay of San Francisco. The 

 caterpillar is somewhat of the coloration of that of Vanessa Antiopa, but short 

 and thick like all the Melitwt caterpillars and beset with short fleshy thorns. 

 The dorsal row of spines is brick red and so is the lateral stripe above the feet. 

 All other parts, both of the body and spines, are black, which tint, being 

 thickly sprinkled with white dots has a bluish luster like the same tint in the 

 caterpillar of V. Antiopa. 



Most commonly this caterpillar is found on Scrophularia, but I have found 

 it also on Diplacus glutinosus and on a Lonicera, related to L. Caprifolium.
