AGATHIS. 399 



^JK 3. Agathis chiriquensis. (Tab. XVI. fig. 7, <? .) 



Niger, nitidus, mesopleuris, mesosterno metathoraceque rufis ; alis violaceis. c? • 

 Long. 11 millim. 



Eab. Panama, David {Champion). 



Antenna? a little longer than the body, densely pilose, involute ; the scape shining, sparsely 

 covered with long hair. Head densely covered with fuscous hair ; the front not much 

 depressed in the centre, the depression indistinctly margined ; ocelli raised. Pronotum 

 with a row of stout keels on its hinder edge ; mesonotum with a shallow channel down 

 the centre of the middle lobe ; an oblique line of large keels on the mesopleura?, and 

 a row of similar keels down their hinder edge near the metathorax ; metathorax coarsely 

 reticulated; metanotum with four longitudinal keels (the central two placed near 

 together, the others nearer the edge), and a stout keel outside the spiracles. Abdomen 

 longer than the head and thorax united, narrower than the thorax, shining ; the petiole 

 long, narrow. Legs densely covered with stiff black hair ; punctured. Wings deeply 

 violaceous, with a narrow, irregular, oblique, hyaline cloud going down from the base of 

 the stigma through the first cubital cellule. Palpi testaceous. 



This insect differs from A. violaceipennis in having the mesopleura? marked with a 

 broad oblique line of carina?; the metapleura? reticulated throughout; the central 

 two keek on the metanotum much nearer each other and not forming a triangle, 

 there being, moreover, only four keels in all ; and the mesothorax red laterally and 

 beneath. 



^\ 4. Agathis albispina. (Tab. XVI. fig. 10, e .) 



Niger, metatborace, coxis posticis supra, femoribus posticis abdomineque rufis ; tegulis, palpis tarsisque anteri- 



oribus albis ; alis fuscis, basi subbyalinis. <$ . 

 Long. 8-5 millim. 



Eab. Mexico, Valladolid in Yucatan (Gaumer). 



Antenna? longer than the body, stout, densely and shortly pilose; the nagellum 

 fuscous. Head shining, the face densely covered with fuscous pubescence, indistinctly 

 punctured ; labrum obscure testaceous ; front deeply excavated ; two furrows, converging 

 at the apex, running down from the ocelli. Thorax covered with a rather long grey pile, 

 impunctate (the metapleurae excepted), and almost shining ; middle lobe of the meso- 

 notum distinct, the sutures reddish ; scutellum keeled, the apex and the sides reddish ; 

 metanotum with two central and two large lateral area? on the upper part, and three 

 area? on the semivertical apical part. Petiole deeply excavated at the base ; the basal 

 half depressed, keeled along the sides, narrower than the apical part, and raised in the 

 centre. Second segment depressed at the base, and with a much wider depression in 

 the middle. Legs (especially the coxa?) densely covered with pale hair.
