Invercargill. Mr. Alf. Philpott sent me a specimen, and 

 Mr. T. F. Cheeseman, the Curator of the Auckland Museum, 

 found a mutilated example on Mount Arthur several years ago. 



Group Cistelidae. 



Omedes apterus, sp. n. 



Oblong-oval, slightly convex, almost glabrous, fuscous ; 

 the legs and antennas testaceous. 



Head rounded and narrowed behind, finely but distinctly 

 and irregularly punctured ; between the eyes there is a broad 

 depression ; the space between the forehead and labrum is 

 very short, almost linear. Labrum reddish, pilose. Ei/es 

 large, but not protruding beyond the lateral outline of the 

 head ; they are touched by the raised antennal orbits and 

 they are quite transverse. Antennce pubescent, reaching the 

 hind thighs, third joint longer than the first, twice the length 

 of the second. Thorax broader than long, finely margined ; 

 the sides rounded before the middle, nearly straight behind ; 

 posterior angles rounded, base bisinuate ; its disk with rather 

 fine, shallow, irregular punctures ; there are two rounded 

 fovese near the middle and two smaller ones close to the basal 

 margin. Scutellum triangular, transverse, red. Elytra finely 

 margined, shoulders somewhat narrowed; each elytron has 

 eight series of rather fine punctures ; there is an additional 

 scutellar row, the sutural two almost form strige and are 

 recurved at the apex ; there is a slight longitudinal impression 

 inside the shoulder; the interstices are minutely and densely 

 sculptured and have a few very fine punctures. 



Tarsi pubescent, the basal two joints of the anterior 

 narrowed towards the base, the second slightly shorter than 

 the first, third short and broad, with a short membrane under- 

 neath ; fourth with a large semitransparent membrane, 

 extending nearly halfway under the fifth ; posterior pair 

 elongate- 

 Most nearly resembles 0. fuscatus ; the terminal joint of 

 the maxillary palpi more transverse and cultriform ; scutellum 

 shorter and broader ; hind angles of thorax more obtuse :
