290 Mr, Waterhouse's Descriptions of 



The antermfe are dull yelloAV, Avith tlie first three joints and 

 the apices of the fourth to tenth joints black, the black scarcely 

 visible on the eighth to tenth joints. The thorax at its widest 

 part about as wide as the head, a little narrowed in front and 

 behind, thickly and strongly punctured, with indications of 

 transverse rugag, the disc with a very small tubercle on each 

 side. The elytra are very strongly and closely punctured, with 

 the margin just at the sinuation and the aj)ex, as well as two 

 dorsal spots, yellow, 



Logisticus, n. gen. 



General build of Toxotus meridianus, but more elongate, and 

 with totally different head. Head long and rather narrow, the 

 portion in front of the eyes a little longer than broad, depressed, 

 a little broader at the apex than in front of the eyes ; maxillary 

 palpi long ; eyes moderately prominent, coarsely granular, nearly 

 contigTious below, narrowly divided above, not much emarginate 

 in front ; antennae as long as the body, slender, inserted on the 

 rostrum in fi'ont of the eyes. Thorax neai'ly as in Toxotus but 

 quadrinodose above. Elytra very long, truncate at the base, 

 narroAved to the apex, each elyti-on terminating in two short 

 spines. Abdomen narrow, acuminate. Legs very long, rather 

 slender, femora not incrassate, tarsi rather broad and very haiiy, 

 the claw joint comparatively short, very slender at the base, 

 suddenly Avidened at the apex, claAvs strong and suddenly bent 

 from the base. 



After a very careful examination, I am of opinion that this 

 genus should be placed next to Artelida in the Toxotince. The 

 produced rostrum, spined apices to the elytra and especially the 

 coarsely granular eyes suggest affinity Avitli the Uracanthince, 

 but the antenna? are not inserted in the emargination of the eye 

 as in that group, and the general Imild of the thorax elytra and 

 legs is decidedly more that of the 'Toxotince. The tarsi are very 

 like those of Artelida^ but the spatulate claw joint is unlike 

 that of any genus that I can remember, and the suddenly bent 

 claAvs are also peculiar. With regard to the coarse granulation 

 of the eyes, it must be borne in mind that an approach to this 

 is already seen in Artelida^ and that great difference exists in 

 the closely allied genera of this group. The granulation in 

 Sag)'idoIa is extremely fine, in Mastododera and Artelida seri- 

 ccus the granulation is much less fine, and in Artelida crinipes 

 it is almost coarse.
