did not secure more specimens. The variation among the workers 

 of a single nest of ants is often very great, and more specimens 

 oi this form would probably show whether it deserves to rank as 

 an independent species. I believe it safe at present to call it C, 

 lineolata, Say, subsp. coarctata, Mayr. n. var." 



I quote the above in the hope that some member of the South- 

 ern California Academy of Sciences may be able to secure more 

 material of this new ant. The species of Cremastogaster are 

 rather easily recognized by their abdomen, which is more or less 

 heart-shaped and shiny. Specimens should be sent to Prof. W. 

 M. Wheeler, University of Texas, Austin, Texas.

Discovery of Another Food Plant of Uranotes (Theckla) 

 Melinus, Hub. 



BY PROF. J. J. RIVERS. 



A flat or somewhat compressed larva was found feeding upon 

 the parenchyma of a pod of a cultivated pole bean (known as 

 Irwin's bean); when disturbed the larva lost its hold and fell to 

 the ground. A slight examination told that it was of the Ly- 

 caenidae. Many pods were excavated after the manner of Dia- 

 brotica, but only to theextent of the inner lining of the legume. 

 Others bored through and attacked the seed and devoured a con- 

 siderable part of a large bean. 



In Dr. Holland's book on butterflies Uranotes melinus, Hab. 

 is mentioned as "one of the hop butterflies" but this citation is 

 incomplete and a little misleading for the butterfly is common 

 where no Htiinulus grow. Another author records it feeding 

 upon Hiimuhis and Crataegus. Thecla humiili Harris, as cited in 

 "Prof. G. H. French's Butterflies" appears synonymous with U. 

 melinus. Hub. As this species has shown in California a partial- 

 ity for Leguminosae it would not be very prophetic to suggest 

 that it might be found upon Lupinus CJiam.issonis so common on 

 our coasts. The tone of color of the larva and the bean pod 

 agree and the texture is similar, the larva having a short, smooth 

 pile, while the pod is less conspicuous, being coated with a bloom 

 having a semi-velvet appearance. 



Chrysalis: held by a few silken threads. The chrysalis is of 

 a dark brown color, head and thoracic parts having an undertone
