margins, and two more or less distinct ones towards the outer side at the apex ; the colour does not differ 

 from the dark bands of the thorax ; underside fulvous, a spot near the second pair of cox* another at 

 the sides of the abdominal segments, and the cavities for the reception of the legs black with a bluish tint ; 

 legs fulvous, all the tibise and the middle of the posterior femora with a black elongated spot; pygidium 

 closely punctured, with a central smooth line, bluish black, the basal margin fulvous; prosternum very 



narrowed behind. # . 



Pemale broader, more square-shaped; underside with the black colour predominating, last abdominal segment 



with a very shallow fovea. 



Eab. Mexico, Juquila, Cordova, Oaxaca (Salle). 



This species may be known by the blackish spot at the base of the fulvous-coloured 

 head and the dark bands of the thorax, which is constant in every specimen, one of 

 which is figured from Oaxaca. 



33. Chlamys kraatzi. (Tab. V. fig. 11.) 



Elongate, subparaUel, obscure aeneous ; antennae and tarsi fulvous; thorax with a moderately high elevation, 

 deeply channelled, closely and finely punctate; elytra with four longitudinal and two transverse raised 

 lines, the interstices deeply excavated. 



Length 2 lines. 



Head finely and closely punctate, with a longitudinal short central impressed line ; antennas transverse from the 

 fourth joint, fulvous ; thorax exceedingly closely and finely punctured throughout, with a gradually and 

 moderately raised elevation of a round shape deeply divided at the top, the division extending, although less 

 deeply, to the anterior margin ; elytra much more distantly and deeply punctured, each elytron with the 

 following raised lines— two oblique costaa running parallel from the base to the suture connected before 

 and at the middle by a highly raised transverse branch, which latter extends also to the third and fourth 

 lines, these last short, the third much shorter than the fourth and interrupted by the transverse costa, but 

 continued behind, and after ruuning parallel and close to the second line is again interrupted by the 

 second transverse costa ; this latter forms two convex branches, the outer one connecting the fourth with 

 the third line ; interstices excavated near the lateral margin ; suture crenulate at its latter half; pygidium 

 very finely punctured near the apex, the rest smooth, opaque, with a narrow but rather deep lateral 

 depression and a short raised central line near the apex ; breast deeply, abdomen finely punctate ; pro- 

 sternum greatly narrowed behind ; tarsi fulvous. 



Eab. Mexico, Cordova (Salle). 



This species is allied to C. elongata by its shape, but differs by its dark uniform 

 colour and the very rounded and finely punctured elevation of the thorax. 



34. Chlamys bipunctatus. (Tab. IV. fig. 24.) 



Elongate, subcylindrical, dark blue, opaque ; head, thorax, and legs fulvous ; thorax with two blue spots ; 

 elytra with six longitudinal elevated lines ; deeply punctate. 



Length 1| line. 



Head rugose, punctate, with a central impressed line ; mandibular piceous ; antennae of the same colour, the 

 two basal joints fulvous ; thorax with a very rounded and rather high elevation, the latter with a shallow 

 groove dividing it through its entire length, basal margin double the width of the anterior one when 

 seen from above ; surface rugose throughout, of the same bright fulvous colour as the head, the top of the 

 elevation with two semicrescent dark blue spots; elytra constricted laterally below the middle, punctate 

 anteriorly, transversely wrinkled at their posterior part, each elytron with six very distinct raised costae, 

 the first from the base to the middle and connected at that place with the second costa running from the 

 middle of the base to the apex in a curved line, the third parallel with the second, but abbreviated behind 

 where it joins the fourth line, which latter is only visible near the apex, the sixth costa runs parallel and
