Hab. Patagonia? 



The specimen from which the above characters are taken is a 

 male, and by accident its label, containing the habitat, is lost ; it is 

 most probably from Patagonia. In general appearance the JV. an* 

 gustata greatly resembles the JV. nodosa, but it differs in being of a 

 narrower form, and in having the terminal joints (the fifth to the 

 tenth inclusive) broader; the anterior tibiae are also broader and 

 rather shorter, and the thorax is longer in proportion to the width. 



The head is distinctly and very thickly punctured in front. The 

 thorax approaches to a quadrate form, but is slightly narrower in 

 front than behind ; the lateral margins form a very slight curve, and 

 in fact are nearly straight ; in front it is emarginated, and the emar- 

 ginated portion is in the form of a segment of a circle ; the hinder 

 margin is but little waved ; the anterior angles are acute, and the 

 posterior angles are slightly produced and rounded at the point ; a 

 faint impressed line borders the anterior and lateral margins : the 

 upper surface is but little convex and finely punctured, but on the 

 disc the punctures are scarcely traceable : the length of the thorax 

 is about equal to three-fifths of the width, whereas in JV. nodosa the 

 length is about equal to half the width. The elytra are very little 

 broader than the thorax, being scarcely dilated in the middle, and 

 are about one-third longer than broad ; they have interrupted and 

 somewhat irregular longitudinal grooves or striae, and the inter- 

 spaces are convex ; the third and fifth most distinctly so : the striae 

 and interspaces on the lateral half of each elytron have distinct irre- 

 gular rugae, the largest of which are for the most part transverse 

 in direction : the legs are long ; the claws are of a pitchy colour. 

 The fifth, sixth, seventh and eighth joints of the antennae are some- 

 what compressed, broader than long, and produced in front so as to 

 present nearly a triangular form ; the ninth and tenth are still broad, 

 but of a somewhat rounded form.

 Hab. Petorca ? 



The whole upper surface of this insect is covered with well-marked 

 irregular rugae ; these are for the most part longitudinal in their di- 

 rection on the clypeus, and there is a transverse indentation marking 

 the posterior boundary of this part : a little behind the line of the 

 eyes is a somewhat irregular transverse ridge, and in the middle, be- 

 tween this ridge and the transverse groove just mentioned, is a short 

 longitudinal ridge. The labrum is rugosely punctured. The thorax 

 is very nearly twice as broad as long ; its anterior and posterior
