40. Papilio eurymedon Bdv 



Same distribution as rutulus and at present probably ex- 

 tinct here. The climate of San Francisco is probably too cool 

 for these two species, and properly wooded land lacking. 



41. Pamphila juba Scudd. 



Taken- by Mr. Cottle in a marshy area at Mountain Lake. 

 May perhaps be still found there. 



42. Pamphila sabuleti Bdv. 



A very cor/mon insect and frequently seen in gardens and 

 public squares. The larva, as is well known, feed on grasses, 

 and as lawns are quite plentiful in the midst of the city, this 

 little insect has no difficulty in maintaining a secure existence 

 here. It is quite generally distributed over the western half of 

 the city. The females vary much in intensity of coloration. 



43. Pyrgus tessellata Scudd. 



Quite plentiful. The larva feeds on Malva sf>. and prob- 

 ably also on Sidalcea. 



44. Thanaos propertius Lint. 



Not common at present. Probably breeds in the oak thick- 

 ets. 



RESUME. 



Of the 43 species of butterflies given as inhabiting San 

 Francisco at one time, probably not more than 30 could now 

 be taken in the course of several seasons, and a newly arrived 

 lepidopterist might well be surprised on learning that such 

 butterflies as A. cpithore, S. sthenele, L. hcteronea and sagit- 

 tigera formerly dwelt here. Furthermore, it is quite possible 

 that such species as C. .vanthoides, L. amyntula, P. occidcn- 

 tails, P. nemorum and others flew in this region. 



Before a decade has passed away there will be but little left 

 of the insect fauna of our city, and therefore the importance 

 and necessity of making local insect lists while the fauna is 

 still extant and in an undiluted condition, cannot be too much 

 emphasized.
