Hub. — On Quercus alba, growing in the sand on the shore of 

 a small pond about ten miles from Stillwater, Oklahoma, Aug. 

 26, 1896 (Prof E. E. Bogue). A. eulecanium occCirred on the 

 same trees. 



K. bo^uei differs from K. galliformis by its larger size, dull 

 roughened surface and dark color, showing red. From K. gilletei 

 it differs entirely in the scale, and also in its much less elongate 

 larva. Oi the European species, it is nearest, perhaps, to K. 

 variegatus, which occurs in the south of France. 



ON TWO REMARKABLE CALIFORNIAN HEMIPTERA. 



By E. Bergroth, M.D. , Tammerfors, Finland. 



Fam. CAPSIDit. 



Dacerla inflata Uhl. 



In the Bulletin de la Soc. Ent.'de France. 1881, p. clvii, the 

 late Dr. Signoret published a short description of a singular new 

 Californian genus of Hemiptera, naming it Dacerla and placing 

 It in the division Myodocharia of the family Lygaeidse. In exam- 

 ining Signoret' s type two years ago, I at once found that it had 

 nothing to do with the Myodochinae. Judging from ihe fades, 

 and without examining the under side of the unique carded speci- 

 men, I thought it was an aberrant genus of Pyrrhocoridae. allied 

 (though not very nearly) to the American genera Arrhaphe 

 H.-Sch. , Phceax Dist. and Japetiis Dist. , and to the African 

 ^enus Myrmoplasta Gerot. , and upon my suggestion it was so 

 placed in vol. ii, of Lethierry and Severin's " Catalogue general 

 ■des Hemipteres." In the Proceedings of the California Acad. 

 Sci.. 1894, Prof Uhler described a new genus and species under 

 the name Myrmecopsis infiaUis, considering it to be a " Capsid, 

 related to Pilophorus.'^ This insect is identical with the Dacerla 

 mediospinosa of Signoret, but as the French author gave no de- 

 scription at all of the species, specific name proposed by Uhler 

 must stand. The genus, however, although very imperfectly 

 described by Signoret, must bear the name Dacerla, the more so 

 as the name Myrmecopsis is twice pre-occupied in Hymenopter- 

 ology. Having now examined the under side of the body, I find 

 that Uhler is perfectly right in placing it in the Capsidae. It is. 

 indeed, related to the divisions Pilophoraria and Myrmecophyaria
