88 Mr. D. Sharp on some 



punctate ; the vertex behmd the eyes not elongate. 

 Thorax strongly transverse, narrower than the wing- 

 cases, rounded at the sides, and narrowed behind ; on 

 each side is a large impression, j)osteriorly somewhat 

 indefinite, and more or less distinctly joined, in front of 

 the scutellum, with its fellow ; the surface coarsely and 

 rather closely punctate. Elytra densely, deeply, and 

 coarsely punctate, dull. Legs black. 



In the male the 2nd and 3rd joints of the antennae are 

 a little shorter than they are in the female. 



The species should evidently be placed with T. tele- 

 phoroides, Bates, in a different section from T. condor. 



Greymouth ; No. 251, Helms. 



Ehinorhynchus, n. g. (Rliinomacerides.) 



Corpus suboblongum, dense punctatum et pubescens. 

 Caput ante oculos subite et valde constrictum ; rostrum 

 tenue, a medio ad apicem paulo latius, deplanatum, oris 

 partibus exsertis. Mandibulse elongatse, graciles, falcatae, 

 extus (et fere certe intus) integres. Antennae elongatae, 

 rectae, subtenues. Elytra sine stria suturali discreta, epi- 

 pleuris angustis sed sat distinctis, linea externa epi- 

 pleurali ad basin parum distincta sed post basin bene 

 elevata. Tarsorum unguiculi brevi, ad basin incrassati, 

 itaque in medio dentati apparent. 



The very distinct rostrum varies according to the sex, 

 being longer and more slender in the female ; it is but 

 little curved ; the palpi and mandibles are conspicuously 

 exposed at its extremity. The anterior coxae are quite 

 contiguous, placed at a distance from the front of the 

 prosternum. The ventral sutures are very deep. The 

 tarsi of normal tetramerous structure. 



This insect is an undoubted member of the small 

 group Rhinomacerides, and appears, so far as I can judge 

 from the description of the European genus Nemonyx, 

 to be closely allied thereto. I have only before me a 

 single pair of this minute creature, and cannot, there- 

 fore, at present fully see its characters. It has some 

 resemblance in general form to Pachyura of the 

 BcUdce, but may be distinguished at a glance by the 

 flattened rostrum and the conspicuously exserted mouth- 

 parts.
