320 MODERN CLASSIFICATION OF INSECTS. 



{fig- 39. 4., 39. 5. antenna), which is of an elongated subdepressed 

 form, and apparently fleshy ; the head rather broad, the legs rather 

 short, and the body gradually narrowed towards the tail, which is 

 entire. The species of this genus reside in sandy situations : the 

 Rev. J. Burrel, however, states that the Op. tibiale had been found in 

 great profusion upon the Lichen rangiferinus {Ent, Trans, old series, 

 i. 312.). It is probably more nearly related to Diaperis. 



Amongst the exotic genera may be mentioned Heterotarsus Latr., 

 in which the ante-penultimate tarsal joint is bilobed, and the penulti- 

 mate joint very minute, as in the Pseudotetramera. The genera 

 Toxicum and Antimachus are remarkable for the horns or spines 

 with which the head or thorax, or both are armed ; Catopiestus 

 piceus Perty, from Java, has the body scarcely thicker than a 

 card. The genus Chiroscelis Lam., has very much the appearance 

 of a large Scarites, with broad palmated anterior tibice, and the 

 antennae terminated by a large globular joint. This insect has been 

 considered to be capable of emitting light from a patch of pale colour 

 on the abdomen ; but M. Percheron has disproved this observation, 

 showing the spot to be a sexual character, and to be opaque {Silherm., 

 Rev. Ent., vol. iii. No. 13.). But the most singular genus, which, 

 indeed, ought perhaps to be considered as the type of a distinct 

 family, is the North American Phrenapates of Kirby (figured in 

 Griffith's An. K.); the tibiae are dentate, like those of the Lucanidse ; 

 the antennae short, and terminated by a 3-jointed club ; the mandibles 

 very large, porrect, and dentated (somewhat as in Uloma cornuta) ; 

 and the head armed with an erect horn ; the palpi are filiform, 

 and the maxillae terminated by a slender corneous lobe. M. Solier 

 has united it with Trictenotoma, and G. 11. Gray with the Bos- 

 trichidae, to neither of which groups does it appear to me to have any 

 affinity. I am indebted to M. Gory for this curious insect. 



The fifth family Blapsidje* Stephens, corresponding with Latreille's 

 Blapsides, and composing, with the addition of the terminal genera of 



* BiBLioGR. Refer, to the Blapsid^.
