8 THE CANADIAN ENTOMOLOGIST 



2. Nilaparvata mahensis Dist. =DeIphacodes mahensis (Dist.)- 



Toya Distant. =DeIphacodes Fieb. 



This genus is described as having a transverse ridge between the eyes, but 

 it has the same carination of the vertex as Delphacodes {Lihurnia of some authors) ; 

 the medio-basal carina dividing the two basal areas is obscure. The pronotal 

 lateral carina slightly divergingly curved, not reaching the hind margin. Vertex 

 as wide as long. Second joint of antennae slightly more than twice the length 

 of the first. First hind tarsal joint slightly longer than the other two together, 

 spur broad, laminate, as long as the first tarsus, small teeth on the hind margin. 

 Toya attenuala Dist. = Delphacodes attenuata (Dist.). 



Kalpa Distant =I>f//j/zacorff5 Fieb. 



1. Kalpa aculeata Dist. = Delphacodes sordescens (Motsch.). 

 This is represented by one female, the type, which, on account of the dif- 

 ference in coloration appears to have more pronounced carinae on the head 

 than has the male. This species and D. bakeri Muir, are peculiar in having small 

 spines on the basal joint of the hind tarsus. 



Akilas Distant. 



I cannot separate this genus from Gelastocephahis Kirk. 



Hapalornelus Stol. 



The spur of this genus is narrow, pointed and thickened, with the inner 

 surface distinctly concave, with many small teeth on the hind margin. The 

 pro- and metanota each have three carina. The long, narrow wings constricted 

 in the middle where the cross-veins are, distinguish it from other genera. 



Sogata Distant. 



The type of the genuss S. dohertyi Dist., is represented by one female. The 

 first hind tarsal joint is longer than the other two together; tibial spur laminate, 

 many fine teeth on hind margin, not so long as the first tarsal joint. Second 

 joint of antennas more than twice the length of the first. Vertex, longer than 

 wide, base Avider than apex; length of face three times the width. This comes 

 very close to Kelesia. 



1. Sogata dohertyi Dist. 



2. Sogata sternalis Dist. Very near to Kelesia kirkaldyi, but it is necessary 

 to dissect out the aedeagus. 



3. Sogata pnsana Dist. Very near to Kelesia fieberi Muir, but it is neces- 

 sary to dissect out the aedeagus. 



4. Sogata distincta Dist. = Megamelus furcifera (Horv.). The type and 

 two other specimens are as above, while four other specimens under this name 

 are Sogata piisana Dist. 



5. Sogata pallescens Dist. Five specimens including the type are Mega- 

 melits furcifer (Horv.), while eight other specimens under this name are Delpha- 

 codes sordescens (Motsch.). 



6. Sogata thoracica Dist. =^ Delphacodes thoracica (Dist.). 



Delphax iinicolor Walk., from Hudson Bay is a nymph and not of a delphacid. 



Matutinus Distant. 



This genus was placed among the Cixiini, but it is a Delphacid, Avhich I 

 consider to be indistinguishable from Chlorionidea Fieb.
