8. Signiphora sp. — A black parasite bred from Aspidiotus nerii ontrueno. San Luis 
Potosi. 
9. Eupelmus sp. ! — Bred from Lecanium olew on oleander. Aguas Calieutes. 
10. Habrolepis n. sp. — Bred from Aspidiotus n. sp. ? (related to A. persew and A. 
fodiens) on orange. Monterey. 
11. Homalotylus n. sp. — Bred from Pseudococcus yucca- on Agave, Guadalajara. 
This genus is known to be parasitic only on coccinellids, which, must have been 
among the I'seudococcus. It is therefore an injurious species. 
12. Pachy neuron sp. ? — From Pseudococcus yuccw on pomegrauate, San Luis Potosi. 
From Pseudococcus yucca; on Agave, Guadalajara. 
13. Pachyneuron sp. ? — Bred from Acanthococcus n. sp. ? on unknown shrub at Valles 
(Tamaulipas). 
14. Tribolium confusum Duv. — From Acanthococcus n. sp. ? Valles. 
15. Vedalia sieboldii Muls. var. — This species was found among the waxy egg 
masses of Icerya purchasi which I collected in Magdalena, Sonora. It is a small 
beetle 3 mm. long, black and red in color; all red below and black above, with two 
large reddish spots on each elytron, one marginal and the other discal. According 
to Mr. Schwarz, it is a true Vedalia, whereas V. cardinally (the Australian impor- 
tation) is not a true Vedalia; Mr. Schwarz thinks there is no reason why V. sieboldii 
should not ilourish north of Mexico in the Sonoran belt, and its importation into 
California might be of much benefit. Unfortunately, it was not found in the egg 
masses until after my return from Sonora, and it was not met with elsewhere on 
the trip. 
16. Ozya orbiyera Muls. — This is a bluish coccinellid, considerably smaller than Chil- 
ocorus. It was found plentifully in Monterey preying on coccids. The large white 
cottony-covered larva' of this species were found with Lecanium hesperidum on leaves, 
branches, and trunk of large trees called "fitolaca,'' in Monterey. Many adults also 
occurred on same trees. The larvae are covered with an abundance of cottony-white 
excretion, with filamentous processes, and strongly resemble specimens of Icerya 
agyptiaca. Larva- numerous, October 17. 
17. Scymnus n. sp. near americanus Muls. — Feeding on Chionaspis citri on orange. 
Tampico. 
18. Scymnus n. sp. near auritulus. —Feeding on Acanthococcus n. sp.! Valles 
(Tamaulipas). 
19. Scymnus sp. ? — Larva- feeding on Lecanium alea- on orange. San Luis Potosi. 
A pteromalid, doubtfully belonging to the genus Arthrolytus, was bred from one of 
these scyinnid larva-. 
20. Chilocorus cacti L. — Preying on Pseudococcus yucca' on agave, etc., Guadalajara; 
on Icerya purchasi on orange, in Monterey. Found in most places devouring coccids. 
21. Tabanus punctifer O. S. — An interesting observation was made in Magdalena, 
Sonora. On the white masses of Icerya purchasi on orange there were found numer- 
ous specimens of T. punctifer, all males, busily engaged apparently in piercing thei 
Icerya; and sucking their juices. I do not know that any similar observation has 
ever been recorded. There was also among them a single male of another, smaller^ 
species of Tabanus (presumably this genus), but it escaped capture. 
It is not unlikely that the males of several species of Tabanida- may prove of much 
good in destroying Icerya and kindred coccids. T. punctifer is found throughout 
the southwestern region, and it will be interesting to know if the male has the 
same habit in California. 
22. Leucopis bellula Willist. — Bred from Eriococcus dubius Valles (State of Tam- 
aulipas). 
23. Phora cocciphila Coq. — Specimens of a fly of the family Phorida- were bred from 
Icerya purchasi collected on orange both from Monterey and Victoria, It is prob- 
ably a true parasite, though this can not be said positively.
