THE CANADIAN ENTOMOLOGIST. 21 



against the ocelli. Front with twelve pairs of distinct fuscous arcs which 

 emit a broad definitely-margined stripe of yellow bearing a black spot 

 above. Pronotum with a submarginal row of irregular spots, heaviest 

 near the margin. Elytra sometimes of a unicolorous dirty straw, 

 sometimes pale yellow, with the spaces between the nervures scarlet,' 

 except along the costa.* 



Described from four specimens from Santa Clara Co., Calif. 

 (Coquillett), and three from Santa Cruz Co., Calif. (Koebele). 



This is a very puzzling form and seems in several characters to 

 connect the Tettigonidcc with the Jassidce through some of the lower 

 forms in that group. 



Paropulopa interrupta, n. sp.— Form of M. scanicus nearly, 

 slightly smaller, vertex flat and not extending behind the eyes ; colour 

 very variable, usually pale straw with interrupted fuscous markings on 

 pronotum and elytral nervures. Length, 2.5-3 mm.; width, 1.25 mm. 



Vertex fiat or slightly depressed on the disc, deeply, coarsely pitted, 

 a little over twice as long on middle as next eye, two and one-half to 

 three times wider than long, the anterior margin rounding or bluntly 

 angulate, face retreating, forming a very acute angle with vertex. Front 

 flat, slightly depressed above, broadest across the antennal pits, from 

 which ridges extend nearly to the apex, forming shallow pits between 

 these and the vertex margin in which the ocelli are located. Whole face 

 deeply pitted, ocelli slightly nearer each other than the eyes, clypeus 

 rounding at the apex and extending some distance beyond the gense 

 Pronotum with the entire posterior margin nearly straight, anterior and 

 lateral margins in a broad curve. Elytra coriaceous, apex bluntly angular, 

 nervures raised, distinct, cells somewhat irregular, often a few extra 

 nervures along costa, a cross nervure between the sectors before the 

 anteapical cells and often two behind this opposite the anteapical cells. 



Colour : very variable, often pale straw, with more or less of fuscous 

 markings on pronotum and with the nervures and margins of elytra 

 interruptedly fuscous, sometimes these marks are arranged in the form of 

 oblique bands. Sometimes the whole insect is of a rather uniform 

 brownish fuscous and sometimes of a tawny reddish shade, the punctures 

 on pronotum are usually dark marked. 



Genitalia: female segment shorter than the penultimate, the 

 posterior margin trianguarly emarginate from the lateral angles clear to
