closed coxal cavities requires yet careful study, as it is not improbable 

 that intermediate degrees exist even in the same species, which makes 

 the conclusion in regard to the state of the cavities uncertain. 



Hyph^nia flavofemoratus, Motscli. (?). 



Closed anterior coxal cavities, unarmed tibise, a square-shaped 

 thorax, and other characters peculiar to Baly's genus are present in 

 an insect contained in this collection, which also agrees very nearly 

 with Motschulsky's species, to which I will refer for the present this 

 insect. The entire upper surface is metallic greenish or seneous. The 

 antennae are as long as the body, obscure piceous with the basal 

 joints fulvous. The head is finely granulate, the lower part being 

 testaceous ; the thorax is square-shaped, with two impressions, finely 

 granulate and punctured (Motschulsky gives the thorax as smooth). 

 The elytra are finely rugose and punctured. The colour of the legs 

 is flavous ; sometimes the tibise and the tarsi are obscurely stained 

 with fuscous. The femora are all of the same thickness, and the first 

 joint of the posterior tarsi is as long as the two following joints 

 together. Claws appendiculate. The underside is nearly black ; and 

 the entire shape of the insect is narrowly parallel with the elytra 

 flattened along the sutural margin. The size of the insect is 1| line. 



Dikoya. 



DoRYScus (gen. nov. Galerucinse). 



Body elongate, parallel ; anterior coxal cavities closed. Antennas 

 filiform, the second joint small, the third double the length. Thorax 

 subquadrate, strongly constricted at the base, the disk biimpressed. 

 Elytra geminate punctate-striate, costate, and pubescent. Tibise 

 mucronate ; the first joint of the posterior tarsi as long as the two 

 following joints together ; claws appendiculate, those of the posterior 

 tarsi very long and curved, united, but bifid at the extreme apices. 

 Elytral epipleurse narrow, but continued below the middle. 



Whether the peculiar structure of the posterior claws in this genus 

 is a sexual character only or to be found in either sex I am unable 

 to say, having only two specimens before me, which agree with each 

 other in every respect. The posterior claw seems to consist of a 

 single piece only, being joined together except at the extreme apices, 

 as is the case, but to a much smaller degree, in the genus Lema. In 

 Doryscus they are very long and curved, while the claws of the four 

 anterior legs are of normal size and appendiculate. The peculiar 

 form of the thorax, in connection with the punctate-striate elytra and 

 their pubesence, are characters which further distinguish the present 

 insect. 



Doryscus testaceus, sp. nov. 



Testaceous ; the sutural and extreme lateral margin narrowly black 

 anteriorly; head and thorax impunctate; elytra strongly geminate 

 punctate-striate, the interstices longitudinally costate. 



Var. Entirely testaceous. 



Length 2 lines.
