STENOTAESUS. 137 



Very similar to S. circumdatus, but smaller; the head and thorax distinctly but 

 closely punctured ; the antennse black ; the marginal line of the sides of the thorax 

 very lightly impressed, the margin flat or a little concave (as it is in S. circumdatus) ; 

 the scutellum black; the elytra thickly clothed with depressed golden hairs, the 

 margins and suture neatly defined with an even orange band ; the abdomen yellow, 

 excepting the middle of the basal segment ; the legs black, including the tarsi, which 

 are pitchy at least. 



An example of this species is labelled " Stenotarsus thoracicus, Guer., type," in the 

 Salle collection ; it is, no doubt, distinct from S. circumdatus. 



10. Stenotarsus tarsalis. 



S. thoracico summa affinitate, antennis articulis duobus, seutello tarsisque rufis, elytris distinctius pubescentibus. 



Long. 5 millim. 

 Mas femoribus posticis minute dentatis. 



Hab. Mexico, Jalapa (Hoge), Cordova (SalU). 



This species is extremely close to both S. circumdatus and S. thoracicus ; from the 

 former the red angles to the thorax and smaller size, from the latter the red tarsi, and 

 from both the red scutellum, appear to separate it ; and it is more probable that there 

 are several closely allied species than that they vary in such points as these. It is, 

 however, labelled S. circumdatus in the Salle collection ; one example from Jalapa has 

 a pitchy scutellum. The toothing of the femora in the male is similar to that of 

 S. rubrocinctus ; I have not at present observed this character in the other allied 

 species. 



11. Stenotarsus rubrocinctus. 



Stenotarsus rubrocinctus, Gerst. Monogr. Endom. p. 324 x ; Gorh. Endom. Recit. p. 25 a . 

 Hab. Mexico 1 2 , San Andres Tuxtla, Playa Vicente (Salle). 



The insect which I refer at present with some doubt to this species differs from 

 Gerstacker's description in having the scutellum red ; it must, however, be very close 

 to, if not identical with, S. rubrocinctus, and is easily known from its near allies by the 

 red legs, and by the antennae being yellow, with the exception of the four terminal 

 joints. In one example before me the teeth on the hind femora are quite distinct. 



12. Stenotarsus militaris. 



Stenotarsus militaris, Gerst. Monogr. Endom. p. 325 * ; Gorh. Endom. Recit. p. 25 \ 

 Hab. Mexico x 2 , Jalapa {Hoge), Cordova, Playa Vicente (SalU). 



S. militaris may be distinguished from the other similarly coloured species by its 

 oblong form and rather acuminate elytra, as well as by the rather distinct but irregular 

 biol. cente.-amee., Coleopt., Vol. VII., March 1890. T*
