728 The American Naturalist. jAugust, 
Chionaspis citri Comst. “ Is the pest of our lime trees here.” 
(Hart in litt.) This extremely pernicious species has not yet 
spread generally through the West Indies, being still unknown, 
for example, in Jamaica. - 
Cotorapo (I.). 
The following species have lately been sent to me from Col- 
orado hothouses by Prof. Gillette. I refrain from giving de- 
tails as Prof. Gillette will shortly publish the full records in a 
paper on the Hemiptera of Colorado. 
*(1.) In greenhouse at Fort Collins: Lecanium hesperidum 
(L.), Aspidiotus nerii (Bouché), A. dictyospermi Morg., A. rapax 
Comst. 
*(2.) In greenhouse at Denver: Lecanium olew (Bern.), L. 
longulum Dougl., L. hemisphericum Targ., L. perforatum Newst.; 
Aspidiotus ficus (Ashm.), A. dictyospermi Morg., Aulacaspis bois- 
dwvalii (Sign.). , 
(Thus, ten species between the two hothouses! The A. dic- 
tyospermi is a species originally from Demerara; I found it 
last year on a palm in Mr. Boyle’s hothouse at Santa Fe, New 
Mexico. A. rapaz is the camelliw of Signoret, but hardly that 
of Boisduval, vide Morgan, Ent. Mo. Mag., 1889, p.351. Since 
Signoret intended no new species, but only Boisduval’s, by his 
name camellic, it is apparent that the name proposed by Com- 
stock has a right to stand.) 
It may be here added that Prof. Gillette also sent me Aspi- 
diotus perniciosus Comst., found on. pears purchased (but not 
raised) in Fort Collins, Colorado. 
New Mexico (N,). 
Lecaniodiaspis yucce Twns. I have lately found several of 
this species on Little Mountain, Mesilla Valley, living on Par- 
thenium incanum (n. o. p.) mixed with Tachardia cornuta Ckll. 
- Coccus confusus Ckll. Mr. A. Holt has found this close to 
the Agricultural College, on Opuntia leptocaulis DC. (n. p,), the 
plant determined for me by Prof. Wooton. (At Tucson, Ari- 
zona, Prof. Toumey finds C. confusus on Opuntia versicolor 
Engelm.)
