 from Pines in California (Hemip.-Homop.). — Proc. Entom. Soc.

Matsucoccus fasciculensis, sp. n., is described from the needles of 

 digger pine {Pinus sahiniana) in various localities in California. Other 

 examples have also been taken from yellow pine (P. ponderosa). This 

 Coccid is closely related to M. matsumurae, Kuw., and is the first 

 representative of the genus recorded from America. The scales 

 are usually found on needles that are one or two years old. Judging 

 from the appearance of cast skins found, there are probably two 

 larval stages preceding the apodous form,

 Species of Opius (Hymenoptera-Braconidae). — Pwc. Entom. Soc. 

 Washington, B.C., xxi, no. 7, October 1919, pp. 161-170. 



The new species described include Opius cupidus, collected on beet 

 and parasitic on Pegomyia hyoscyami, Panz. ; 0. turneri, reared from 

 a Dipterous leaf-miner on cowpeas ; 0. downesi, from pupae of Rhago- 

 lefis pomonelJa ; 0. richmondi and 0. lectus, swept from blueberry 

 barrens, where they occur in company with 0. melleus, Gah., and may 

 have the same host, viz., Rhagoletis jjomonella. 



In addition to the above species from North America, 0. trinidadensis 

 and 0. cereus are described as parasitic on the fruit-flies, Anastrepha 

 striata, Schin., and A. serpentina, Wied., in Trinidad ; the former 

 may be only a geographical race of 0. craivfordi, Vier,

Myzocallis zelkoivae, sp. n., is described from the winged viviparous 

 female, the sexuales not having been found. This Aphid is common 

 on the underside of the leaves of Zelkowa keaJci in Tokyo and also on 

 cultivated beans. Greenidea kuwanae, Perg., is frequently found on 

 young shoots of Quercus from May until the end of summer. 



Nippolachmis piri, Mats., is one of the most injurious pear Aphids 

 in Japan, occurring on the underside of the leaves. Most of the 

 Aphids of this group have no alternate food-plants and are found on 

 the branches or stems of trees, but N. piri spends the winter and spring 

 on Eriobotrya japonica and the summer and early autumn on pear 

 trees. 



ChaitophorinelJa acerifoliae, Tak., is common on the leaves of Acer 

 palmatnm in spring and is also found on A. carpinifolium and 

 Aesculus sp. C. koelreuteriae, Tak., occurs on Koelreuteria macroculata. 

 C. kuwanai, n. n., previously recorded as Chaitophonis japonica, 

 Essig & Kuw., is found on Acer pictum. 



Stomaphis yanonis, Tak., occurs on Celtis sinensis. In S. quercus, 

 L., winged females appear three times in a year, but in S. yanonis 

 only a few individuals of the second generation are usually winged. 



Rhopalosiphum sambucicola, Tak., is closely related to R. magnoliae, 

 Essig & Kuw. The winter and early spring generations occur on 

 Sanibucus racemosa and the summer ones on Dioscorea japonica, 

 Lagerstroemia indica, Celastrus articulatus and Citrus sp.
