Florida. In Tampico, Mexico, Townsend found a variety of Conchaspis 

 (Dn/nrci, Cockerell, on Jrihisnis. There are, in addition, several quite 

 l)robk'niatical species reported from tlie same genus of plants: Pulriii- 

 aria cestri, Boucbe, Lecanium hromelioe^ Coccus erion, Anderson, and C. 

 trichodrs, Anderson. The last two are from II. ro.sa-sinensis. II. {Abd- 

 vioschus) esculent UK, Linna'us, is a food plant of Diaspis aiiiyffddJi. The 

 unidentified Coccus oofjencs, Anderson, lives on Thespesia (olim Hibiscus) 

 2)(>i)uhic(i, TiinuM'US. In Jamaica the cotton ( (rossypinm Jtarhadcnse) grown 

 about the town of Kingston becomes infested by I>((cfi/lopius virgatus, 

 Cockerell, Cliionaspis minor, ^laskell, and IHaspis ami/f/ddli, Tryon. In 

 China, on cotton, is the unrecognized IHaspis or rather Chionaspis flos- 

 fii/pii, Fitch. 



Professor C. II. T. Townsend wrote me from Brownsville, Texas, 

 Aprils, 1895: 



I mail yoii ln!r«!\vitli some scales I found on cotton the other day. They are all I 

 have. Could find no more. It is the iirst seale I have ever found on cotton. 



The material was very scanty, but with little doubt belonged to 

 Lecanium imhricatum, Cockerell. Professor Townsend had the follow- 

 ing note on the fresh specimens: 



Liver-colored, verj' convex, oltlon.n, with a broken longitudinal carina. Scah; 

 transversely and r.ather irregularly ribbed on sides. The broken keel siiows .a whiter 

 surface tliau the rest. Length of large scale, 4 A mm. ; width, ',\ mm. ; lieight 2 mm. or 

 slightly over. Smallest scale is 1| mm. long. 



STERCULIACE.^. 



A large order of tropical herbs and trees. The Indian I'riolnmn 

 hoo]ccrian<(,W\'g^ht and Arnot, is a food ])lant ol' Tuchardia lacca, Kerr. 

 Comstock records Lecanium ole<v, Bernard, from ^^ Brachaton,^^ meaning 

 perhaps lirachj/t-lilton. Sasaki reports IHaspis pafeUi/ormis, Sasaki, 

 iVom >iterculi<i pUiianiJ'olia. 



TILIACE.^. 



A cosmopolitan order of over three hundred species. Crcwia cxccha, 

 Vahl (syn. roihii), a native of the oriental and Ethiopian tropics, 

 exhibited sonu^, exogenetic CeropUisies florideusis when cultivated in 

 Jamaica. Triumfctta rJioniboidea, Jac(iuin, also in .Jamaica, nourished 

 some Ceroplastes cerifcrus, Anderson.' 



Tlic temperate-zone genus Tilia supports several coccids, namely 

 Aspidiotus (ineylus, Putnam, A. tilia', Signoret, Myfilasjyis poniorum, 

 Bouche, I'ulrinaria inntimerabilis, liathvon, Lecanium tilicc, Cook, 

 A'ylococcus fili/erns, Loew, and the pioblematical Lecanium vagabnndnm, 

 Kaltenbach. The species of Tilia infested is not in every case clear. 

 L. titi(v and X. filifous are from T. fjrandifoHn, niore correctly called 

 T. platyphijllos, Seopoli. Aspidiotus tiliwiiud Mytilaspis linearis [porno- 



' Anier. Nat., ISO."), p. 731.
