372 THE CANADIA.N ENTOMOLOGIST. 



The abdomen is rougher, more hairy and duller than that of A. pltivialis. 

 The form of the process of labrum at once separates it from A. anogr^. 

 The two following species are entirely black, with black pubescence ; 

 they have the colour of A. Porterce, but are larger and stouter, and have 

 not the strongly produced clypeus of that insect. They are considerably 

 larger than A. nigerrima, Casad. 



Andretia pertristis. n. sp. 

 %. — Length about 15 mm.; black, with black pubescence, that on 

 sides of metathorax slightly brownish ; wings deep fuliginous ; clypeus 

 ordinary in form, strongly and very densely punctured all over, except a 

 shining median line ; malar space practically •obsolete ; process of labrum 

 narrowly truncate, with sloping sides ; thorax above dull, with a dense 

 velvety pubescence ; enclosure of metathorax a nearly equilateral triangle, 

 the sides of which are gently concave, the lateral ones bounded by an 

 incised line, the surface of the area marked by an irregular rather coarse 

 wrinkling, not forming distinct plicae, and not confined to the basal portion; 

 abdomen closely and very minutely punctured. 

 Hab. — Los Angeles, Calif. (Davidson). 



Andreiia rubtristis, n. sp. 

 ?. — Length about 13 mm.; black, with black pubescence. Differs 



from A. pertristis by its smaller size ; wings only slightly dusky ; third 

 submarginal cell much shorter ; the densely punctured clypeus without a 

 smooth line ; last joint of flagellum reddish beneath ; process of labrum 

 with its apex thickened and having a slight pit; area of metathorax shorter 

 (the angles of the triangle extremely acute), and rather more coarsely 

 sculptured. 



Hab. — Los Angeles, Calif, two (Davidson). Others are in the 

 collection of the American Entomological Society. Long ago named as 

 new in MS. by Mr. Davis, of Cambridge, but the name he used is not 

 available.
