624 THE DISTRIBUTION OF SCALE<>INSECTS—COCEEBELL.

still without ii recnid. In tbe Lesser Antilles we have one or two addi- 

 tional records due to Mr. Barber; thus Dominica now has two instead 

 of one, Montserrat six instead of four. Martinique has a record of 

 Dkispis lanatiis (Insect Life, Vii, p. 288). Puerto Eico still seems to be 

 without a record. 



The recent visits to the West Indies of Dr. Riley and of Mr. Hubbard 

 who gave spe;'ial attention to Coccid.e, will r.o doubt in due time lead 

 to many new records, for which we must wait until the material can be' 

 worked over. 



There now remains ]Me\i(*o, which I will for convenience treat as a 

 whole, although parts of it are hardly neotropical. Until recently (and 

 now, so far as published records go) the Mexican list stood at 28, hav- 

 ing gradually attained that figure in the following manner: 



Species kuo wn before Signoret's " Essai " ( 1818-1868) 



Species acldetl by Siguoret in his "Essai " (1869-1876) 3 



Species added by Comstock (1883) 2 



Species added by Riley and Howard in Insect Life 3 



Species found by Dr. A. Duges (1886-1894) 5 



Species found by the present writer on journey tLrough Mexico in 1893 12 



Total 28 



Having in view this deplorable want of information as to Mexican 

 Ooccida?, the Department of Agriculture lately sent Prof. C. H. T. 

 Townsend into that country to collect these and other insects. I 

 examined the Coccidic collected, and may remark that they add con- 

 siderably to our knowledge; but beyond this, I do not now feel at 

 liberty to go, since they are the property of the Entomological Division, 

 which has the right of first announcing the discoveries made. 



NEARCTIC REGION. 



A catalogue of the uearctic species has appeared in the Canadian 

 Entomologist for February, 1894, and I understand that Mr. Ashraead 

 has in press a complete bibliographical list of all nearctic Heteroptera 

 ami Ilomoptera, including also those of the northern portion of the 

 neotropical region. 



In the Canadian Entomologist's list, I was so unfortunate as to acci- 

 dentally omit Dactijlopius ephedrw, Coquillett, 1890, Lecanium tarsale, 

 Signoret, 1873, and Ortliezia catajjJiracta, Shaw {Cliiton, Zetterstedt). 

 The last mentioned has, according to Hart, been found in Greenland, 

 as well as in Ireland and Scotland. 



Furthermore, since my list appeared, it has been shown that Aspi- 

 fliotus convex lis is not a valid species, and that ^1. abietis and A.pini are 

 synonyms of A. abietis (Schrank) of Europe. I do not think Mr. Pet- 

 tit's manuscript A. abietoides can be any better distinguished from 

 abietisj and until he sets forth some reasons for maintaining its validity, 

 it had better be left out of account. Eiley's manuscript A. corticalis 

 must also be droi)ped until we are informed what specific characters it 

 exhibits; likewise his Ceroplastes artemisiw. Lecaniodlaspls yuccce can
