SPONGILLA-FLIES— PARFTN ANT) GURT^TEY 495 



In striata, the antennae are banded with a brownish black portion 

 between the basal and distal yellow portions, whereas in californica 

 the antennae are more or less solidly brownish black, sometimes 

 becoming only slightly lighter toward the apex. Tlie wings of tenebra 

 have the greatest amount of brown on the membrane, and are the 

 darkest of the species of Climacia. The notch in the anterior margin 

 of the male parameres is shallower in striata than in californica. 



Climacia chapini, new species 



Figure 22; Plate 2, figure 2 



Male (holotype) : Head with vertex yellow, faintly reddish in 

 center, small brownish spot behind antennal socket adjacent to eye; 

 face yellow; palpi yellow; basal antennal segment light yellowish 

 brown (rest missing); legs yellow, faint brownish traces on coxae; 

 pronotum yellowish with blackish brown mottling dorsally, indication 

 of a short longitudinal dark brown naiTow streak medially not reaching 

 anterior or posterior margin, also a shorter posterolateral longitudinal 

 streak on each side, mesonotum and metanotum yellowish brown 

 dorsally, pleura with brown streaks particularly anteriorly, some 

 yellow posteroventrally; abdomen yellowish. 



FoREwiNG (pi. 2, fig. 2) : Length 3.8 mm., width 1.6 mm.; membrane 

 yellowish with three pronounced dark brown spots, the first the basal 

 radiomedial streak, longitudinally elongate, crescent shaped, beginning 

 about where K. and M approach each other basally, with the anterior 

 margin of streak running slightly anterior to Rs+MA and Rs to a 

 point between 1st r and 1st r-m, the posterior margin running along 

 Rs+MA and MA to slightly beyond 1st m, then ciu-ving back an- 

 teriorly to meet the distal end of anterior margin of streak; the second, 

 the antepterostigmal spot from costa to subcosta; and the third, the 

 dark brown intervenational anal streaking basally from near 2d A to 

 margin; most longitudinal veins brown except for costal vein to and 

 beyond antepterostigmal spot, Rl to just before 2d r, and short basal 

 portions of MA from radiomedial streak to slightly before 1st r-m; 

 MP, Cul, Cu2, 1st, 2d and 3d A pale basally; inner and outer gradates 

 and radial cross-veins brown, bordered, subcostal cross-vein brown; 

 costal ends of costal cross-veins yellow, subcostal ends brown except 

 for two basad of antepterostigmal spot; pterostigmal cross-veins in 

 center, 1st m between MA and MP14-2, 1st and 2d m-cu, cubito- 

 anal and anal cross-veins yellow; light brownish streaks between 

 longitudinal veins from region of outer gradates to margin and from 

 branches of Cu to margin; Rs forking into R24-3 and R4-f 5 basad 

 of point of coalescence of Sc and Rl; MPl+2 with first branch at 

 angle, closer to stem of MP than second fork; R2+3 with terminal 

 fork slightly distad of 3d r; Cul with four branches to margin in left 

 wing, three in right; three radial cross-veins, 2d r to Rs before fork,
