MTTTILLA. 271 



12. Mutilla subrobusta. (Tab. XIII. fig. 10, ? .) 



Mgra ; tliorace ferrugineo, abdominis apice late aureo-serieeo. § . 

 Long. 6 millim. 



Hah. Panama, Bugaba 800 to 1500 feet, Volcan de Chiriqui 2500 to 4000 feet 

 (Champion). 



Black ; the basal half of the antennae, the thorax, and legs ferruginous ; the knees, a 

 mark on the apex of the median segment, the breast, and the pleurae more or less, black ; 

 the apex of the first and second abdominal segments, the sides of the latter and two 

 lines running from its base to the middle, a mark on either side of the third, fourth, 

 and fifth abdominal segments, and the edges of the ventral segments, silvery-white. 

 The head not very strongly punctured, closely covered with dull golden pubescence 

 and with some long black hairs. The eyes moderately large, the head obliquely 

 narrowed behind them. The scape of the antennae covered with white hair, the 

 flagellum with a silvery pubescence ; the third joint one half longer than the fourth. 

 Thorax quadrate, about twice the length of the head, very slightly contracted inwardly 

 at the middle, a little dilated towards the apex ; the sides roughly crenulated ; the 

 apex rounded, with a semiperpendicularly rounded slope ; the pro- and mesopleurae 

 smooth, impunctate. The abdomen a little shorter than the head and thorax united ; 

 the second segment with distinctly separated punctures all over, its apex and the 

 following segments covered with a fiery-red, iridescent pubescence; the pygidium 

 thickly covered with dull fulvous hair. The femora slightly, the tibiae and tarsi thickly, 

 covered with glistening white hair ; the calcaria pale ; the spines fulvous. 



This species has the general coloration of M. centralis, but it is smaller ; the head 

 is covered with a brassy pubescence, the apex of the thorax is more rounded, and the 

 third and following segments want the white maculae and are fiery-red. 



** Abdomen black. (Species 13-16.)

Bab. Guatemala, Paso Antonio 400 feet (Champion) ; Panama, Volcan de Chiriqui 

 2500 to 4000 feet (Champion). 



Black ; the basal half of the antennae, the thorax, and legs red ; the knees black ; 

 the apex of the first abdominal segment, two longitudinal lines on the second segment 

 reaching beyond the middle, a line on the apex of the same segment, two longitudinal 

 lines running from this to the apex of the abdomen, and the edges of the ventral 

 segment, silvery-white. The head coarsely punctured ; the vertex sparsely covered with 

 long black hairs ; above the antennae and behind the eyes more thickly clothed with
