The species of this section have a greater resemblance to the genus Goniolanguria 

 than those which follow ; I do not think it necessary, however, at present to give them 

 generic rank, but if I am not mistaken the following points of difference will unite a 

 group including some undescribed species from South America : — the legs very thin 

 and long; the head very depressed and very smooth, the eyes prominent; and the 

 apical segment of the abdomen almost keeled, the central line being a definite ridge, 

 but not raised, and also subacuminate. D. subulatus is one of the brightest of the 

 Central- American " Languriides," the elytra being usually of a bright metallic green 

 inclining to rufous at the base, while the head and thorax are piceous with a green 

 reflection. The mouth is rufous ; the antennae of moderate length, with an elongate 

 club of five joints. The thorax is half as long again as wide ; in the female the sides 

 are nearly parallel at the base, and from the middle narrowed and rounded a little to 

 the front angles ; the base has a transverse depression terminated on each side by the 

 punctiform but obsolete striolse, and the impressions on this are ill-defined, and the 

 central lobe is short. Scutellum transverse. The elytra at the base are as wide as the 

 thorax. The colour beneath is more or less evenly rufous ; and the legs are clouded 

 towards the knees, and on the tibiae. The roughening of the front femora is not very 

 distinct, and as it is present in a small degree in the females does not form a good 

 sexual diagnostic. In the longer hairs of the front tarsi there is as much difference as 

 usual. 



A good series of this insect was secured by Mr. Champion. 



3. Dasydactylus glabricoUis. 



Biceus, infra dilutius, supra saturatius et aeneo-micans, nitidissimus ; capite prothoraceque fere glabris ; elytris 

 subtiliter punctato-striatis, interstitiis crebre punctulatis, apicibus latius rotundatis et denticulatis ; pro- 

 sterno truncato, lsevi. Long. 10-12 millim. tf 5 . 



Mas tarsis anticis fusco-birtulis.

 (Janson) ; Panama, Bugaba, Volcan de Chiriqui (Champion). 



Smaller than D. subulatus, and with a shorter and consequently more quadrate 

 thorax. The elytra are wider at their base than any part of the thorax. The femora 

 in the male appear to be quite smooth, and the tibiae seem only to differ from those of 

 the female by their greater length. Although there are but a few specimens from each 

 of the localities, and these differ a little in size and colour, I believe they represent but 

 one widely distributed species.
