DOEYPHOEA. 247 



This, again, is a species similarly coloured to D. semiambita and D. subfastuosa, but 

 may be known by the punctuation of the elytra, which is fine and distinctly geminate 

 punctate-striate at the anterior portion, the rows uniting closer, and becoming simply 

 punctate-striate towards the apex, where the interstices are very finely rugose and 

 aciculate. The colour of the thorax and the head is very nearly black, and the 

 general shape of the insect larger and less convex and rounded, while the elytra are 

 also less shining, owing to the fine aciculate interstices between the punctures. I have 

 four specimens before me, which agree perfectly with each other.

Hal. Mexico 1 2 , Cordova (Salle) ; Guatemala, Purula (Champion). 



In the type and two other specimens from Mexico before me the dark colour of the 

 elytra is interrupted at the base, the middle, and near the apex by three narrow dentate 

 flavous bands, which extend to the similarly coloured band near the lateral margin ; 

 in two other specimens from Purula and Mexico respectively these transverse bands 

 are interrupted at their outer ends; the punctuation of the elytra is also stronger 

 and rather more irregular. But these differences are perhaps attributable to local 

 influences. 



13. Doryphora lativitti s . (Tab. XV. fig. 10.) 



Greenish black ; thorax finely punctured, subopaque ; elytra strongly punctate-striate, the interstices finely 

 punctured, fulvous or flavous, the sutural and lateral margins, a broad transverse band before, another 

 behind the middle, and the apex obscure piceous or blackish. 



Length 5 lines. 



Head flat, opaque, greenish, very minutely punctured, the clypeus more strongly punctate ; antennae with the 

 first six joints shining, the first two joints testaceous below, the three terminal ones opaque, longer than 

 broad. Thorax of nearly equal width, transverse, the sides straight near the base, rounded near the 

 anterior angles only, the latter pointed but not much produced ; surface of the same silky opaque colour 

 as the head, remotely covered with fine punctuation not stronger at the sides than on the disk. Elytra 

 broad, convex, and parallel, rather strongly and regularly punctate-striate, the striae placed remotely, 

 the interstices finely punctured, the punctuation very fine, and almost disappearing near the apex; 

 . obscure fulvous or flavous, the sutural and lateral margins as well as the extreme apex greenish black or 

 piceous ; a band of similar colour and very regular shape extends across the suture below the base towards 

 the sides, where it is abbreviated at a little distance from the lateral margin ; another band of the same 

 size is placed below the middle, the ends of which are slightly narrowed and turned upwards. Meso- 

 sternal process robust and curved. 



Eab. Guatemala, Senahu, Panzos, San Juan in Vera Paz (Champion). 



In the design of the elytra this species completely resembles D. bella, and also 

 closely D. blanda, Stal. I am compelled to separate it from the first on account of the 

 many specimens I have for comparison, agreeing in every respect with each other. The 

 insect is of broader and more robust shape than D. bella, the transverse dark elytral
