24. Dakruma coccidivora Comst.?—Larve feeding on <Acanthococcus n. sp.? on 
unknown plant. Valles (Tamaulipas). 
25. Chrysopasp.—Victoria, October 16. Larva found preying on Icerya purchasi on 
orange. 
26. Chrysopa sp.?—Monterey, October 17. Attacking Icerya purchasi. 
27. Psocus sp.?—Found eating Aspidiotus n. sp.? (related to A. persew and A. 
fodiens) on orange. Victoria, October 16. 
Norre.—At Guaymas and Hermosillo, in Sonora, Vedalia cardinalis is well known 
by reputation. [am informed that Don Luis Torres, governor of Sonora, brought 
the Vedalia to Hermosillo from Los Angeles, Cal., in 1895. Specimens were taken in 
June, 1894, to Aranjuez, near Guaymas, and placed on the five or six Icerya-infested 
orange trees on that place. They seem to have done their work well at Aranjuez, for 
all the Iceryas I found there seemed to be dead and empty. They ought now to be 
well distributed by the authorities in Magdalena (where there are many thriving 
colonies of Icerya), and in Victoria and Monterey. 
INJURIOUS INSECTS OTHER THAN COCCIDS. 
Material was collected on the trip that does not appear below, as only 
species of economic importance are mentioned. 
1. Aleyrodes corni Hald. ?—Specimens of this species were found on leaves of orange 
in Guadalajara; and on orange, lime, and Catalpa leaves in San Luis Potosi. 
2. Aleyrodes sp.?—On leaves of orange, Tampico. 
3. Aleyrodes sp.?—On leaves of Tecoma stans, Guaymas. 
4, Aphides.—Plant lice often occur on orange in Sonora and other parts of Mexico. 
They were mentioned as injurious in Guaymas in summer months. 
5. Cicada sp.—Apple twigs at Magdalena, Sonora, showed unmistakable signs of 
having been largely oviposited in by a Cicada. The same was observed in twigs of 
deciduous fruit trees at San Ignacio. 
6. Heanthus niveus Serv.—Found at San Ignacio, Sonora, September 26, on tobacco. 
Reported to have caused much injury in August (1894) by eating holes in the tobacco 
leaves in this district. 
7. Papilio cresphontes Cram. (?) (orange dog).—An orange dog, the larva probably 
of this Papilio, was found on orange, eating the leaves, in Guadalajara. It was also 
found on orange in Vactoria and Monterey. 
8. Thyridopteryx sp.?—A bagworm, apparently of this genus, is very bad on orange 
in parts of Mexico. It was found on orange at Guaymas, where I was told it caused 
much injury in midsummer. It also occurs on the orange trees in Hermosillo. It 
was found in large numbers on the orange trees in Guadalajara, and was also found 
on orange in Tampico. 
9. Ligyrus ruginasus Lee.—Great numbers of these beetles were observed attracted 
to light at night at Magdalena, September 26. Also at Nogales (on border). These 
immense numbers indicate much injury, in case they breed in roots of any crop. It 
is possible the lary breed in Helianthus, though it is very likely that they infest 
roots of sugar-cane which is grown in the Magdalena region. 
10. Oneideres putator Thom.—This grayish species was found girdling branches of 
Acacia, near Chocoy (State of Tamaulipas), October 15.. It is not improbable that 
it may attack fruit trees also. 
11. Trypeta ludens Lw.? (orange worm or maggot).—The oranges which come from 
the State of Morelos to Mexico City are badly infested with maggots. These are 
with little doubt the larve of this fly, which is fully treated of in Insect Life (vol. 1, 
p. 45). These wormy oranges come principally from Yautepec. So far this orange 
maggot does not seem to have spread to the other orange regions of Mexico. 
NoTE.—Succinea brevis Dkr. and Praticolella griseola Pfr.—These two species of 
snails were found on branches and trunks of orange trees in Tampico. The several 
specimens of S. brevis had all been infested with a sarcophagid fly, belonging to the 
genus Sarcophilodes, ee . os
