tudinal nervures, without any transverse branches. The 

 ovipositor is about the length of the cerci ; it is slender, and 

 curved upwards. The first joint (metatarsus) of the posterior 

 tarsus has a pair of long apical spines. 



Length, 7 mm. ; pronotum, li mm. ; posterior femur, 

 5 mm. ; ovipositor, 1-| mm. 



Gryllodes maorius, Saussure, Melange Orthop., p. 377. 



This species is put down to New Zealand by Saussure on 

 the evidence of a specimen in the Berlin Museum. I have 

 never seen it. The following is Saussure's description : 

 " Reddish-fuscous, with grey tomentum ; head fuscous, with a 

 yellowish transverse band above the antennae ; lobes of the 

 pronotum washed with testaceous. Elytra much shortened, 

 covering the first abdominal segment, contiguous at their 

 bases. Ovipositor shorter than the hind femora, the valves 

 rather depressed, slightly acute. Mediastinal vein un- 

 branched. Head globose, moderately broad between the 

 antennae. Pronotum rather flat above. 



"Length, 13-5 mm.; pronotum, 2-4 mm.; hind femur, 

 8 mm.; ovipositor, 7 mm.; elytra, 3 mm. Width of pro- 

 notum, 7 mm." 



The genus Gryllodes differs from Gryllus in having a nar- 

 rower front between the antennge. The auditory pit on the 

 inner side of the fore tibia is generally absent. The media- 

 stinal vein of the elytra is unbranched in the female, and 

 singly branched in the male ; the dorsal field of the female is 

 longitudinally veined. In Gryllus the mediastinal vein has, 

 generally, several branches, and the dorsal field of the female 

 is, generally, rhomboidly reticulated.

ipeinacrida) . 



I have examined the type of this species and find it very 

 distinct, but it undoubtedly belongs to the genus Hemideina. 



The anterior femur has no apical spines. The middle 

 femur has an apical spine on the inner side, as also has the 

 posterior femur, and the latter is armed below with eight 

 strong teeth in the outer and seven in the inner row. The 

 hind tibiee above have five spines in the inner and four in the 

 outer row. The middle tibia has two spines on the upper side, 

 while below there are three in each yo\\\ The fore tibia has- 

 no spines above, and below there are four in each row. The 

 pronotum is strongly roughened, the meso- and meta-nota 

 slightly so. The abdominal terga are smooth; the second, 

 as well as those following, is emarginate. 



The two spines on the upper surface of the middle tibia, 

 place this species in a separate group from the others.
