diagonal carinae across basal portion of basal plate are very unusual and 

 seem to be the support of the endomeral sac. Species represented by the 

 9 holotype, cf allotype, and 3 cf cf and 1 9 paratypes. 



Menacanthus koreae, new species 

 Figure i:9,b 



Type, 9 adult (cT unknown) from Picus canus jessoensis Stejneger, 

 collected by C. Fennel, at Kwangnung Kyonggi-do, Korea, Apr. 7, 1957. 

 Type in USNM. 



Note: The name of host on slide is Picus canus griseoviridus, which has 

 been placed under the synonym of P. c. jessoensis. 



Diagnosis: The host of this species is conspecific with that of Mena- 

 canthus picorum (Eichler), but since specimens of picorum have not been 

 seen by the author it is not possible to make a comparison between the 

 two. It is possible that the present species may prove to be conspecific 

 With, picorum (Eichler), but it is hardly likely. 



M. koreae is very close to pici dryobates (Eichler) in size, but the thoracic 

 segments differ considerably (see table). The frons is decidedly conical, 

 with rounded tip; the temples are rather narrow, giving the head a tri- 

 angular shape; thoracic segments small, in comparison to abdomen and 

 head, and abdominal pleurites clearly visible, as well as the outer end of 

 sternite VIII. The coxae are unusually large, with femora and tibiae 

 short and thick, the tibiae thickened distally. Especially noticeable are 

 the rather heavy spines on second and third coxae and all femora, with 

 the usual spines on tibiae somewhat thicker. The patches of setae on 

 femora are more like spines than setae, while the patches on the sternites 

 are of usual thickness. 



Unfortunately the species is known by a single female so that the male 

 genitalia cannot be checked with others. Measurements follow next 

 species. 



Menacanthus bruneri, new species 



Figure i:IO,a 



Holotype, 9 adult, and only specimen, from Dendrocopos v. villosus (Lin- 

 naeus), collected by Prof. Lawrence Bruner at Harrison, Nebr., Feb. 25, 

 1895. Type in USNM. 



Diagnosis: Of rather large size, with very short and wide head, the 

 frons being very flatly conical, the ocular slit prominent, and the temples 

 narrow (longitudinally) ; sides of prothorax straight and of pterothorax 

 but slightly convex ; narrow pleurites and last, wide sternite clearly visible, 

 the fringe of setae on the latter short and sparse; first and second coxae 

 large, third small and elongate; third femora and tibiae unusually long. 



Measurements of types are given below.
