160 coccinellim:. 



duplici laterali pone medium parva, sutura latius, pone medium in maeulam subquadratam dilatata, 

 margineque apicali nigris pernitidis ; antennis pedibusque runs. Long. 3| millim. 



Hab. Guatemala, Totonicapam, San Geronimo (Champion). 



The short and rather convex form of this insect is somewhat suggestive of Brachyacantha, 

 and it a little resembles B. lepida in pattern. There is a slight metallic appearance in 

 the black pattern of the thorax and elytra. The head is white and spotless, the eyes 

 rather large. The thorax is very short at the margins, longer in the middle (as the basal 

 margin is arcuate), and has the sides strongly deflexed ; the black pattern of the disc is 

 divided by a middle line, and is notched opposite the front angles so as to form a square 

 spot there. The elytra vary a little in pattern in the two specimens before me — the 

 one from San Geronimo has two large transversely squarish spots on the suture united 

 by the black sutural line, and a large and rather angular spot occupying the callus, and 

 on the margin, nearly opposite the hinder sutural spot, is a small spot (this being double 

 in the Totonicapam example) ; the apical margin is less distinctly black, and in both 

 specimens only as far as the lateral spot. 



This is an exceedingly neat, pretty species. It is difficult to compare it to any other 

 I have seen without fear of misleading ; the markings are somewhat suggestive of those 

 of Propylea conglobata, but the insect is more convex and more shining than that species. 



The Totonicapam specimen is figured. 



15. Coccinella concinna. 



Oblonga, depressa, subobovata, albida, subtus nigro-picea ; capitis basi et epistomate, prothoracis lineis duabus 

 ad basin ampliatis, marginem anticam baud attingentibus, scutello, sutura, macula pone medium fasciiforme 

 et nonnunquam duabus alteris parvulis, una in callo humerali, una quam hsec paullo posteriore nigro- 

 piceis ; elytris creberrime obsolete punctatis ; pedibus luteis. Long. 3| millim. 



Hal. Panama, Volcan de Chiriqui 8000 feet (Champion). 



This little species has the form of Adalia, but at present I prefer associating it with 

 C. compta, to which it bears some resemblance. The sides of the thorax are evidently 

 rounded and contracted in the hmd angles, so as to form a break in outline with the 

 elytra. The margins of the thorax and of the elytra are moderately expanded and 

 reflexed. The elytra are widest behind the middle opposite the larger spot ; this latter 

 is of an irregular form, but indicates an oblique fascia nearer to the base at the margin 

 than at the suture (in none of the three examples before me does it reach either) ; in 

 one example the two smaller spots are wholly wanting, they are both submarginal, the 

 first actually on the callus ; the sutural pitchy-black line vanishes near the apex, where 

 the limb alone is pitchy. 



The body beneath is black, smooth, and not punctured ; the mesosternum has a 

 shallow impression for the reception of the prosternal process ; the coxal depressions 

 on the first ventral segment are ill defined, the lines proceeding from the intercoxal 

 process being shortened and not touching the hind margin of the segment. The middle 

 and hind femora have a dusky cloud in the middle.
