Chrysochraon anomopterus, n. sp. (Truxalinae). 



Description, male, female unknown. Very like japonicus Bolivar and genicul- 

 aribus Shiraki, but does not agree with either sufficiently well to be considered 

 identical. It differs from both the above mentioned species in lacking a longi- 

 tudinal stripe of brown on the sides, the entire insect being an almost uniform 

 brownish yellow color, faint indications of dorsal and lateral longitudinal stripes 

 on the head, and the genicular arcs of the hind femora are barely darkened; the 

 spines of the tibiae are black in the apical half; there are no spines on the femora; 

 the hind tibiae slightly more clear yellow than the rest of the insect. The

antennae are noticeably flattened in the basal third and are longer than the 

 head and thorax. The tegmina are much broadened in the apical half and the 

 tip truncate and mesially notched, as shown in the accompanying figure; the 

 hind wings are aborted, being decidedly shorter than the thorax. The cerci are 

 simple, cylindrical and pointed, as long as the flat triangular apically pointed 

 supraanal plate; subgenital plate with the tip broken off. Mesosternal inter- 

 space more than twice as long as broad, the metasternal lobes but little separa- 

 ted. 



Length, pronotum,4 mm.; antennae, about 10 mm.; tegmina, 12.5 mm.; hind 

 femora, 13 mm. 



Described from a single male, the type.

Catantops viridifemoratus, n. sp. (Acridinae). 



This rather pretty grasshopper is placed in the above already 

 unwieldy genus with considerable doubt. It runs to that genus 

 in the keys of Brunner, however, and the specimens show no 

 characters incompatible with those of Catantops. 



Description, male and female. General color brownish. Head greenish 

 brown with broad black postocular bands and some small maculations on the 

 occiput, varying in size, position and number, sometimes forming a rather uni- 

 form dorsal infuscation; eyes large and globose, especially in the male where 

 they are but a little longer than broad while in the female they are almost half 

 as long again as broad; frontal costa entending almost to the clypeus, sulcate 

 only at and below the ocellus, the sides parallel, or converging slightly at the 

 ocellus; interocular space approximately as broad as the frontal costa, slightly 

 narrower in the male than in the female; vertex lightly sulcate above, without 

 median carina, anteriorly meeting the face roundly, in the male with a scarcely
