136 THE ENTOMOLOGIST. 



Hab. Falls Church, Virginia, August 26th and September 

 7th (Nathan Banks). T. donatus I have from Ames, Iowa. 



From the descriptions this may seem somewhat like T. 

 ivyomingensis, Ckll., but that has the pattern of the first abdo- 

 minal segment entirely different ; and the colour of the light 

 bands of banksi, when placed beside ivyomingensis, appears quite 

 different — a sort of pale bluish by contrast. 



Epeolus semilectus, sp. nov. 

 $ . Length about 9 mm. ; black, shining ; vertex, mesothorax, 

 scutellum, and pleura with very large irregularly-placed punctures on 

 a shining surface, the punctures dense in places, in others sparse ; face 

 with silver-white hair ; labrum black, mandibles red in middle ; second 

 antennal joint red beneath, and scape red at extreme base ; light 

 markings white, not noticeably yellowish (but not bluish) ; mesothorax 

 with two rather inconspicuous stripes ; middle of ventral surface of 

 abdomen densely covered with white hair ; scutellum strongly bilobed, 

 the axillar teeth sharp, but not surpassing it ; tegulae apricot-colour ; 

 wings with the basal half hyaline, the apical half strongly rufo-fuscous ; 

 legs red, but the trochanters, and the hind femora and tibiffl, mainly 

 black, the hind knees broadly red, however ; spurs on hind legs brown, 

 on middle ferruginous ; abdomen shining, with the punctures small 

 and feeble ; the light bands on apices of segments very narrow, that on 

 the first broadly interrupted ; transverse black area on first segment as 

 broad as possible, ending obtusely and rather suffusedly very near 

 lateral margins ; extreme hind margins of segments, especially the 

 apical ones, brownish ; basal part of apical segments brownish ; apical 

 plate broad ; ventral segments two and three with narrow white hair- 

 bands. Close to E. lectus, Cresson, but abdomen not strongly punc- 

 tured, half of wings darkened, and band on apex of first abdominal 

 segment broadly interrupted. Still closer to E. lectoides, Kobertson, 

 but only one band interrupted. It may perhaps be a geographical race 

 of lectoides, which is known at present from Illinois. 



Hab. Falls Church, Virginia, July 4th (Nathan Banks). 



Epeolus vemonice, sp. nov. 

 $ . Length 7^ mm. or a little less ; vertex, mesothorax, scutellum, 

 and pleura coarsely rugose ; colour black, including scutellum, but 

 tubercles and axillar teeth bright ferruginous red; clypeus very minutely 

 and densely punctured ; face with much silvery hair, slightly stained 

 with yellowish about base of antennas ; labrum black, with two little 

 ridges on its lower half in the middle ; mandibles ferruginous, simple ; 

 antennas brown-black ; pubescence of thorax and abdomen above, 

 forming the light markings, pale ochreous ; mesothorax with two 

 lines, not very conspicuous ; scutellum emarginate in middle ; axillar 

 teeth large, conspicuously surpassing scutellum ; pleura crossed by a 

 rather indefinite band of light hair ; tegulm bright apricot-colour ; wings 

 dusky hyaline, the apical margin broadly much darker ; stigma amber- 

 colour, nervures fuscous ; legs red ; middle femora with a blackish 

 sbade beneath, hind femora mainly black beneath and behind ; spurs 

 black; abdomen broad and convex, with fairly broad entire bands on all
