234 EXOTIC NEUROPTERA. 



2. Cross-veins in four series, or rather irregular (except first series), 



hind femora thickened- testaceus. 



Cross-veins is three series; hind femora normal capensis. 



There is also another African species in which the front 

 femora are black on the apical half, probably a new species. 



Paiiorpa niexicaiia n. sp. — Pale yellowish ; antennae, except 

 basal two joints, black; thorax unspotted ; wings hyaline, a transverse 

 brown spot over forking of radial sector, a narrow band below basal 

 part of stigma, somewhat bent and interrupted beyond the middle, ex- 

 treme apex very narrowly brown, and a narrow brown band before tip 

 (in one wing interrupted); venation black, the five cross-veins in api- 

 cal part of wing pale; stigma pale yellowish. Wings slender; the 

 subcosta runs into the costa much before stigma in all the wings ; 

 stigma long and slender; radial sector connected back to radius twice, 

 once at stigma ; behind the basal connection is a cross-vein between the 

 lower branch of the radial sector and upper branch of median, the fork- 

 ing of median hyaline. Fifth abdominal segment without tooth or 

 process, sixth rather short, seventh more slender than usual. Expanse 

 25 mm. 



Type. — d". From Orizaba, Mexico (Crawford). 



TRICHOPTERA. 

 Plectrotarsus graveiihorsti Kol. 



Several specimens from Hobart, Tasmania, differ in sev- 

 eral respects from Kolenati's description, but also vary 

 among themselves. All are females, and have the mouth- 

 parts as figured. The radius is plainly curved at stigma, 

 and several specimens have an extra fork in apical part of 

 wing as in figure, in one specimen the discal cell in the hind 

 wings is very much longer than in the others. The speci- 

 mens in good condition show three hyaline spots on each 

 fore-wing covered with snow-white hair, one at base of the 

 third apical cell, one on the thyridium, and one on arculus ; 

 the " margine antico croceo " of Kolenati is scarcely evident, 

 except in one specimen. From Kolenati one would infer 

 that the legs, except tarsi, were pale ; in these specimens the 

 legs are black, except the front femora and hind tibiae, and 

 in two specimens the front femora are blackish. The spines 

 are very prominent, longer than the width of a joint. 



I should think that the insect should be placed in the 

 Limnephilidae, or rather, Phryganeidae.
