yellowish (instead of white) hair on under surface and sides of head and thorax, and 

 the somewhat more slender maxillary palpi. There is also a superficial resemblance 

 to E. hoUii, but that species has white hair on first abdominal segment, no long black 

 hairs on second, glittering golden hairs at apex of abdomen, a much larger and more 

 quadrate head, etc. 



Photopsis anas-pasia n. sp. 



$. Length about 7| mm.; head round, not quite as wide as thorax; eyes 

 convex, strongly polished, slightly oval, not visibly facetted; a small round tubercle 

 above each antennal socket; scape about as long as next four joints together; third 

 joint longer than fourth, and much longer than second ; head rather densely punctured ; 

 mandibles simple; thorax short, moderately narrowed behind, with large deep dense 

 punctures; femora robust, slightly swollen in the middle; tibife large, somewhat 

 flattened, with stout ferruginous spines; femora with scattered small punctures, but 

 they are quite numerous and stronger on posterior face of hind femora; abdomen 

 broad, first segment sessile on second; second with deep punctures, which are neither 

 confluent nor elongated; carina on first ventral segment distinct, prominent but 

 obtuse anteriorly; pygidium large, strongly margined, delicately longitudinally striate, 

 except the apical fourth. 



Ferruginous; narrow apex of second abdominal segment, and the segments 

 following, and the femora and tibiae, black or nearly so; antennae ferruginous; head 

 and scape with appressed white pubescence; thorax and second abdominal segment 

 above with appressed golden-red pubescence, that on the second abdominal segment 

 not so dense as that on thorax; apex of second and following segments fringed with 

 dense white hair, except that in the middle of 3 to 5 the hair is dark brown, forming a 

 large patch, which however does not reach the second segment; scape, occiput, 

 prothorax, sides of thorax, legs and underside of abdomen with long white hairs; an 

 elongate tuft of white hair on each extreme side of second segment; maxillary palpi 

 light ferruginous ; apical half of mandibles black.

P. anaspasia belongs in Fox's group anthophoroe, and runs in his table, except as 

 to structure of antennae, to aspasia or phaedra, but does not agree with the description 

 of either of these. The color is too red for aspasia, the antennae are not fuscous, and 

 aspasia has no patch of dark hair before the apex of abdomen. From phaedra it is 

 distinguished by the color of the antennae and abdominal pubescence. In Melander's 

 table for the same group (Trans. Anier. Ent. Soc, 1903, p. 319) it runs near to P. 

 impar, but differs entirely in the color of the hair on second abdominal segment.
