Entomophthalmus decipiens, n. sp. 



Black; tip of protliorax, antennae, and legs (femora 

 infuscated) reddish. Uniformly clothed with short ashen 

 pubescence . 



h lead with dense partially-concealed punctures ; with a 

 short medio-basal carina. Antennae long, thin, and lightly 

 serrated, second and third joints very short, fourth almost 

 as long as fifth, fifth to tenth subequal in length, eleventh 

 distinctly longer. Protliorax strongly transverse, quite 

 parallel-sided except for the slightly rounded front angles, 

 basal angles acute and acutely carinated, with a short medio- 

 basal carina, front margin with a fine carina, each side of 

 which has a short spur projecting obliquely backwards; with 

 dense small punctures. Elytra feebly diminishing in width 

 posteriorly ; with crowded asperate punctures at base and on 

 tips, becoming smaller and more clearly defined elsewhere, 

 near suture and on tips with fairly well-defined striae, else- 

 where with but feeble remnants of same. Prosternal sulci 

 deep, narrow, and parallel-sided, except at extreme base ; 

 propleural parallelograms about four times as long as wide. 

 Length, 2f mm. 



Hab. — Northern Queensland (Blackburn's Collection).

In general appearance, except as to the antennae, very 

 close to Microrhagus serraticornis. Bonvouloir's figure of 

 E. interrujjtus (pi. xxv., fig. 9) will give a good general idea 

 of the species. The antennae at first appear to be quite 

 distinctly ten-jointed, but on close examination the supposed 

 third joint is seen to be really two, the third being very short 

 and closely applied to the base of the fourth ; under a com- 

 pound power the suture between them is seen to be oblique, 

 and the third to be about one-fourth of the fourth and much 

 shorter than the second (in this respect it seems to be similar 

 to loriai, from New Guinea). The only other Australian 

 species of the genus (uniformis) was described by Blackburn 

 as "rufo-ferrugineous."
