VOLUME XI. 



On the Mortli American ASIL.IDAE fI>as.vpo;;oninae, I^a- 

 plirinue), with a new genu<i» of SYKPIIIDAK. * 



BY S. W. WILLISTON, -M. D. 



In the following pages I have endeavored to tabulate the genera of 

 Diis)jpogon!ii(ie and Laphrinae from the United States. The genera 

 SphagcuH from Cuba, Arc/iilestris, LusfaHrus, Ahgapoda and Pacudorus 

 from Mexico and Fsllociinis from Texas are not included, all of which 

 have but one known species each. Dlzontna (1 sp. Tex. and Fla.) 

 and Blacoiha ( 1 sp. Texas) are unknown to me and their positions have 

 hence from necessity been wholly drawn from figures and descriptions. 

 On the other hand there are added Tn'cds, ILdjropogoii, JIj/priTc/u'd 

 and Maria, not hitherto recorded from North America ; whether cor- 

 rectly or not the detailed descriptions I trust will show. A new generic 

 name is also proposed, and the earlier name of Ihromijia adopted fur the 

 species of Dioginitea. Laparus ? picflftirsis Bigot from California does 

 not belong in that genus, nor can it be well placed with Cti/fiiiiciiK to 

 which it is most nearly allied. Moreover several species now placed 

 under Cz/rfopngmi are provisional, and will some time require generic 

 separation. Altogether then, with the genera and species herein added, 

 thirty-five genera with one hundred and twenty-five species of Daxypn- 

 gintlnae and eleven genera with fifty species of Laplirlnne represent the 

 extent of our knowledge in these two sub-f\imilies in North America. 



The Ast'/inrir are but little known. From the Western regions I 

 know three species of Mallophont, three of rromachits, three or four 

 of Pioctacnntltiia, five or six of Kin.r, with others of To/iiicnts, 

 Mdc/ii'miis, and a number whose positions I am in doubt about. Oni- 

 iiKifiiis. two species of which I know from New Knglaiid and (Jeorgia, 

 I have not yet seen elsewhere.
