Liphanthus sabulosus, Reed. 



This insect was described by Reed as a new genus of 

 Pliilanthidfe. Friese and Diicke refer it to Psaenythia^ but 

 it is a peculiar little species, with remarkably long filiform 

 male antennae, and I am inclined to accept Reed's generic 

 name. A specimen from the British Museum is labelled 

 " Chili," and Mr. Meade-Waldo informs me that Philippi 

 had proposed a new generic and specific name, which was 

 not published. 



Tetralonia hirsulissima, sp. n. 



? . — Length about 14 mm. 



Robust, black ; the head, thorax, and two basal segments 

 of abdomen with long erect white hair ; sides of face, vertex, 

 and cheeks anteriorly with black hair; head extremely broad; 

 mandibles robust, black, with no orange spot ; labrum 

 covered with white hair; clypeus strongly punctured; 

 antennae black, third joint almost as long as next three 

 combined ; mesothorax dull ; no intermixture of dark hair 

 on thorax above ; legs with hair mostly white, but black on 

 inner side of basitarsi and dark chocolate on inner side of hind 

 tibioe ; hind spurs not hooked ; tegulffi black. Wings dusky 

 translucent, venation ordinary. Abdomen with white hair- 

 patches at sides of segments 2 to 5, that on 2 rather small, 

 the others large, transverse, and brilliant white ; other parts 

 of these segments (except second) black ; apical segment with 

 shining chocolate hair ; venter with bands of white hair. 



Hab. British Columbia, 4. 11. 07 {Capt. O. A. Beazeley; 

 British Museum). It also has a type-written label, " Toba." 



Among the North-American species it falls nearest to 

 T. lata (Prov.), described from Vancouver I., but it is easily 

 known by the long white hair and spotted abdomen. It has 

 a South-American aspect, recalling such species as T. hi- 

 punciata, Friese. The locality may be erroneous ; could it 

 have come from Chile, where the bees are so often black and 

 greyish-white haired ? I do not find any S. -American species 

 with which I can identify it. 



Protandrena scutellata, sp. n. 



$ . — Length nearly 7 mm. 

 Rather slender ; head and thorax black, with very scanty
