two lateral, rosette- like groups of spines; abdoniinal s[)iiies directed posteriori}-; 

 all spines bearing long hairs; entire dorsal surface bears smaller spines inter- 

 n^.ixed with those mentioned above. 



Adult.- — Mycotretus piilchra. This was described by Sa\- in 1<S2() (Jour. 

 Phil. Acad. Nat. Sci. V, 301; ibid. II, 345) under the generic name Tritoma. 

 It is about 3 to 3.5 mm., long, ovate, with the head, thorax and scutellum black, 

 the elytra red with the apical third obliquely black, the black extending forward 

 on the sides almost to the humeri. The head and thorax are finely and sparsely 

 punctured, the punctures of ehtral strict are fine, the intervals finely punctate. 



Smith- records it from Hudson County and Woodside, N.J., with the state- 

 ment that it was once common. Blatchley^ states that it is frequent in Marion, 

 Vigo, Knox and Posey Counties, Indiana, April 9-June 19, and in Chagnon's 

 Coleoptera of Quebec^ it is listed from Rouville Co., June, Montreal Isl., June 

 and La\al Co., August. 



A NEW GENUS AND SPECIES OF APHID FROM JAPAN. (HEM.) 



BY RYOICHI TAKAHASHI. 

 Forest Experiment Station, Meguro, Tokyo, Japan. 



This interesting aphid, which is found in the leaves of Podocarpus macro- 

 phylla, is rather inactive in habit. Both winged and wingless forms appear in 

 May and later, in the second and subsequent generations. The sexuparse are 

 wingless, but most interesting is the fact that the oviparous female, as well as 

 the male, is winged, these forms appearing during the month of September. 

 As is common for species belonging to the Siphonophorina, wingless viviparous 

 females may give birth to both winged and wingless progeny, but winged females 

 produce only wingless forms. 



Neophyllaphis, new genus. 



This genus is closely related to Phyllaphis Koch, but differs from it aS 

 follows: 



1. Sensoria on the third segment very peculiar in shape, being trans- 

 versely narrow. 



2. Body of the wingless form covered with white secretions which are not 

 thread}-. 



3. The oviparous female is winged. 



Winged female. — Body rather narrow and without hairs. Frontal tubercles 

 absent. Antenuit nearly as long as body, six- segmented, spur of last segment 

 \-ery small, sensoria on third segment transversely narrow (ring- like in the ovi- 

 parous female). Ocelli prominent. Abdomen without tubercles. Wings 

 hyaline, the third oblique twice branched. Cornicles very small and much 

 wider than long. Cauda not globular, but is constricted at base and slightly 

 so at middle. Anal plate slightly sinuate. Empodial hairs absent. 



Wingless female. — Similar to the winged female. Body with a white 

 pulverulence. Eyes very small. Third antennal segment without sensoria. 



Type. — Neophyllaphis podocarpi, n. sp.
