half as broad as the tegmina, suddenly broadens by a narrow interior 

 shoot to double or more than double its former width, and then 

 passes nearly at right angles to the costal border, but directed a little 

 obliquely outward, slightly broadening as it goes, to the outer mar- 

 gin, which it turns toward the anal angle, narrowing and fading 

 until it has traversed nearly or quite three-quarters of the anal area; 

 its margins are ill defined and slightly irregular, but its general 

 form is a sickle-like curve, which greatly resembles that of most spe- 

 cies of Spharagemon. Hind femora ash-gray, with two or three 

 faint, ill defined, slightly oblique fuscous bands. Hind tibise yellow, 

 the spines black tipped. Length (of an average specimen), cf, 19 

 mm., 9, 28 mm.; of antennre, cf, 8 mm., ?, 9.75 mm.; of tegmina, 

 d", 24mm., ?, 30 mm.; of hind femora, d", 11 mm., ?, 13.5 mm.

Trimerotropis lauta. Head livid gray, completely sprinkled 

 with fuscous dots, giving a fuscous appearance to the upper surface; 

 antennas dirty dull luteous, annulate, with dark fuscous on basal 

 half. Pronotum fiat above, the front lobe dirty yellow, its posterior 

 half tuberculate ; posterior lobe livid, heavily dotted with reddish 

 brown on the little rugosities; upper half of lateral lobes reddish 

 brown, lower half like the head. Tegmina scarcely shorter than the 

 hind legs, obscure pellucid on basal half, heavily flecked with light 

 brownish fuscous blotches, mostly concentrated into a large broken 

 patch, occupying most of the basal third of the wing, and a triangular 

 patch in the middle of the wing, its apex next the costa; outer half 

 of wing pellucid, sprinkled almost uniformly with small moderately 

 distant subequal faint fuscous spots. Wings pellucid, with no trace 

 of any band, a few of the apical cells filled with a fuscous cloud. 

 Hind femora reaching the tip of the abdomen, ash gray, with a pre- 

 median and postmedian narrow lateral oblique brownish fuscous 

 stripe. Hind femora livid, flecked with fuscous, with a faint pale 

 prebasal annulus, the apex infuscated and the spine-tips black. 

 Length of body, 15.5 mm.; of antenna?, 8.5 mm. ; of tegmina, 18 

 mm. ; of hind femora, 8.5 mm. 



1 <$. Guadalupe Island, off Lower California (E. Palmer). Dried 

 after immersion in alcohol. 



Remarkable for the entire absence of a band, which in the other 

 Guadalupe species, T. vinculata, reaches the extremest dimensions.
