XYLOCOPA VIRIDIS Smith. 



Alhajuelo, Panama (Canal Zone), March 7 and 12, 1912 (Busck). 



XYLOCOPA VARIANS ECUADORICA Cockerell. 



Alhajuelo, Canal Zone, May 28, 1912 (Busck). A male, differing 

 from the female only in the usual sexual marks, and the abdomen 

 having very distinct but narrow marginal white hair-bands at sides 

 of segments 2 to 5. The cheeks have erect white hair, mixed with 

 black above. Face narrow, orbits distinctly converging above; 

 cl3^peus, supraclj^peal mark, lateral face-marks, labrum, broad stripe 

 on mandibles, front of scape, and narrow stripe on basal part of 

 flagellum, all very pale yellowish ; clypeus with scattered black hairs. 

 The tegulae are dark, with a red spot in front and the outer margin 

 red; in typical varians they are wholly red. 



XYLOCOPA TABANIFORRnS Smith. 



A male, Mexico (C. F. Baker collection, 2499). This has black 

 tegulae ; Smith, describing a female, says they are ferruginous. The 

 face-marks agree with those of var. clmiquiensis Perez, except that 

 they are sulphur yellow. 



XYLOCOPA RUFINA (Maidl). 



Both sexes from Mexico (C. F. Baker collection, 2321). Maidl 

 described this as a variety of X. tahaniformis, but I believe it to be 

 distinct, since the abdomen of the male is broad like that of the 

 female, and the orange-ferruginous hair on the abdomen is very dis- 

 tinctive. The male also has larger eyes than tabaniformis, and the 

 hair on the cheeks is black. There are no lateral face-marks. Baker 

 had labeled this " tahaniforrnis?'''' 



XYLOCOPA RUFINA ILLOTA, new subspecies. 



Female. — Length, 18 mm. Similar to X. ruflna, with interrupted 

 orange-fulvous bands on abdomen, but hair of head and thorax dark 

 mouse-gray (that of cheeks gray, not black) ; process of labrum more 

 slender; surface of clypeus perfectly dull (moderately shining in 

 ruflna) ; tegulae black. 



Mexico (Baker collection, 2154). 

 Type.— C2it. No. 20699, U.S.N.M. 



MESOTRICHIA CALENS MALAGASSA (Sanssure). 



Antanambe, Madagascar. Both sexes. 



MESOTRICHIA ALBICEPS (Fabricius). 



Mount Coffee, Liberia (R. P. Currie). Agrees with one from F. 

 Smith's collection, labeled Gambia.
