Eucerceris angulata Rohwer, new species. 



Judging from the description the following new species is related to 

 Eucerceris punctifrons (Cameron), described as an Aphilanthops, but the 

 clypeus does not project outwardly, the relation of the ocelli with the eyes 

 and each other is different, and the color is somewhat different. In some 

 respects Eucerceris chapnunto? Viereck and Cockerell, seems to be related 

 to this species, but the description of chapmance does not fit the present 

 insect in all ways. 



Female. Length 11 mm. Clypeus flat, median portion with a short, flat, 

 truncate process which narrows apically and is on the same plane as the face; nasal 

 eye margins distinctly diverging beneath; facial quadrangle much broader beneath 

 than high; frontal carina uniform in width, not impressed; mandibles of the narrow 

 type; antennae rather short, the third joint much shorter than the two following; 

 postocella line somewhat shorter than the ocelloccipital line and much shorter than 

 the ocellocular line, neither of the latter are equal with the third and fourth antennal 

 joints as in punctifrons; lateral anterior angles of pronotum obtusely, distinctly 

 dentate; propodeal enclosure punctured similar to the propodeum, with the usual 

 longitudinal sulcus; entire insect closely, rather coarsely, distinctly punctured; 

 abdomen normal, pygidium about two and a half times as long as broad, rounded 

 apically, broader basally, hypopygidium with a very deep U-shaped notch. Black: 

 spot on median part of clypeus, frontal cariba, large spot on sides of face, spot on 

 superior orbits, line on pronotum, metanotum, angles of propodeum, bands of first 

 to sixth dorsal segments, uniform in width on first, narrowed in middle on following 

 and interrupted on four and five, yellow; legs black, four anterior tibse beneath pale, 

 tegulae black, piceous, and yellow, wings subhyaline, radial and subcostal cells 

 fuscous; costa and stigma reddish-yellow, rest of venation dark brown, pubescence 

 sparse, silvery. 



Lower California, between San Jose del Cabo and Triunfo. One female collected 

 by 'Albatross' Expedition, 1911.
