60 PHTTOPHAGA. 



Black, covered below with short white hairs ; posterior half of the thorax bright fulvous, anterior margin 

 narrowly yellow; surface closely and deeply punctate; scutellum white; elytra black, sutural and lateral 

 margins (the latter interrupted) shining white. 



Length 2-2^ lines. 



Eab. Mexico 1 . 



Suffrian only knew a single female of this curiously coloured species. I have now 

 another male insect before me, from the collection of Mr. Baly, which is smaller and 

 has the sutural white margin abbreviated posteriorly, the lateral one being only indi- 

 cated by a short streak of white below the shoulder. It is not improbable, therefore, 

 that specimens with totally black elytra may be met with. The specimen figured is 

 that of the Berlin Museum.

Scolochrus cazicus, Suffr. Monogr. vii. p. 119 \ 



Below black, silvery pubescent ; sides of the abdomen and the posterior thighs yellow ; thorax and a spot 

 between the eyes fulvous ; anterior margin of the former narrowly black ; elytra black, shining, a sub- 

 quadrate sutural spot at the base yellowish white. 



Length 2 lines.

This species is very closely allied to S. montezuma. I do not think it at all impro- 

 bable that it is but a variety of that species. It is true that S. cazicus is a shorter 

 insect, which two specimens from the collection of Mr. Baly confirm ; but in regard to 

 the colour, no great reliance is to be placed on that, as other species of this genus 

 show ; and both the present one and S. montezuma were described by Suffrian from 

 single females. The figure on our Plate is taken from a Mexican specimen. 



7. Scolochrus suffriani. (Tab. IV. fig. 7.) 



Black below, covered with thick white pubescence ; sides of the abdominal segments and part of the posterior 

 thighs yellow ; posterior part of the thorax fulvous, the anterior margin black ; elytra yellowish white, a 

 narrow basal margin and a transverse band near the apex black. 



Length 2-| lines. 



3 . Eyes nearly contiguous ; antennae fulvous, their five terminal joints black ; thorax deeply foveolate- 

 punctate at the sides, the interstices transversely wrinkled, to a smaller extent on the disk, the black 

 anterior part much widened towards the middle ; scutellum yellowish white : elytra deeply punctate- 

 striate, the extreme apex smooth, the interstices very minutely rugose ; yellowish white, the sutural and 

 lateral margins, the humeral callus, and a streak from the latter to the suture, together with a transverse 

 band below the middle, narrowed interiorly, black: posterior thighs extending to the end of the 

 abdomen. 



Hab. Mexico, Tehuantepec (Salle). 



I do not think I am wrong in considering the present insect a different species from 

 the preceding ones. It is, although a male, larger than the females of the latter. The 

 thorax is more deeply punctured, forming even small foveas ; and the interstices are 

 wrinkled. The white colour of the elytra predominates, and only leaves a transverse 

 black band, although this may be subject to variation. The female is unknown.
