A. (Wagneriana) undecimtuberculatus (Keyserling) is kno^vn from 

 t Colombia, Panama, Guatemala, Mexico, Florida, Cuba (Santiago de las 

 Yegas) and Haiti. 



A. (Eriophora) variolatus (Cambridge) is found in southern and 

 western United States, Mexico, f Guatemala, Tenezuela and St. Vincent. 

 It is probably in the Greater Antilles also. 



A. (Metazygia) wittfeldae (McCook) is known from fFlorida, Mexico, 

 the Bahamas and Havana, Cuba. ^Ve took it at Mavaguez, Porto Rico, 

 in a hotel. 



Gasteracantha is widely distributed in the tropical and subtropical 

 regions of the world. G. cancriformis (Linnaeus) is found from North 

 Carolina and California to Paraguay; the Bahamas: El Guama, Santiago 

 de las A^'egas and Havana, Cuba (according to Banks under the name of 

 hexacantha Fabricius) ; Haiti and Jamaica. T\^e have it from the Ba- 

 hamas, Jamaica, Mona and Banos San Yincente in Cuba. G. hiJaris 

 Thorell is recorded from fSt. Bartholomy, Porto Rico (Aguadillo and 

 Adjuntas), and Haiti. In Porto Rico we found the under side of leaves 

 of young coco palms at San Juan and also in the mountains south of 

 Arecibo festooned with its webs. Banks has referred G. canestrinii Cam- 

 bridge to this species, thus extending its range to Antigua and Dominica, 

 but Petrunkevitch does not follow him in this. G. sexserrata (Walck- 

 enger) is recorded from f Cayenne, Haiti and Porto Rico (Bayamon). I 

 took it several years ago on Key I^argo, Florida, so it is probably in Cuba 

 also. G. tetracantlia (Linnaeus) is recorded from California (if pallida 

 Koch be a synon}an), Haiti, Culebra, St. Thomas, St. Yincent, Guade- 

 loupe and three of the Grenadines. We can now add to this list Porto 

 Rico (near Arecibo) and Desecheo. 



Micrathena is the Acrosonia of autliors. As now constituted it con- 

 tains more than 125 species, all American, and the great majority trop- 

 ical. M. armata (Olivier) is known only from fHispaniola and Jamaica. 

 M. cuhana (Banks) is recorded only from fSan Diego de los Banos and 

 possibly Havana, Cuba. We took it in Cuba at Banos San Yincente. 

 M. flavoinaculata (Keyserling) is known only from Haiti: and forcipata 

 (Thorell) only from Cuba. J/, liorrida (Taczanowski) is recorded from 

 Mexico, Peru, fCuiana, Brazil and Jamaica; obtuspina (Keyserling) 

 from f Mexico to Brazil and also from Porto Rico. Finally, 7-ufo punctata 

 (Butler) and sloanei (Walcken^er) are kno^ii only from Jamaica. It is 

 decidedly curious that there are no records of the genus in the Lesser 

 Antilles. 



Glyptocranium is strictly an American genus. The related Old World 

 genera are found in Australia, Africa and southern Asia. It has two
