BEMBIDFLA.—MONEDULA. 97 



Coxis posticis in utroque sexu infra in spinam productis ; abdominis segmentis 2°-4 m late flavis, sexto rufo- 



flavo. <$ £. 

 Long. 12-16 millim. 



Hab. Mexico \ Navarrete in Tepic (Schumann), Venta de Zopilote 2800 feet, Eio 

 Papagaio 1200 feet, both in Guerrero (H. H. Smith), Temax in North Yucatan 

 ( Gaumer). 



Black ; the inner and outer orbits of the eyes (the former broadly), the clypeus, the 

 scape beneath, the mandibles at the base, the edges of the labium, the femora more or 

 less, the tibiae, the tegulae and tubercles, citron-yellow ; the edges of the pronotum, a 

 more or less large mark on either side of the scutellum, the metanotum, the edge of 

 the median segment at the top, the lateral projections, sometimes an irregular narrow 

 curved line on the first segment, and the other segments, except a narrow black line at 

 the base (the apical one entirely, except at the extreme apex), yellow. The four 

 anterior femora are yellow beneath to near the base as well as at the apex, the hind 

 femora being yellow at the apex only; the tarsi are yellow, with a decided rufous 

 tinge. Head above covered with long grey hair ; the vertex broadly depressed laterally, 

 opaque, strongly aciculate ; clypeus convex, the apex almost transverse. Pro- and 

 mesothorax (especially above) finely and rather closely punctured. Last ventral 

 segment indistinctly carinate, laterally with some scattered punctures, the apex sharply 

 rounded ; beneath keeled in the centre, the sides a little depressed. Hind coxae with 

 a sharp triangular tooth on the inner side. 



In the male the hind coxae are toothed as in the female ; the yellow marks on the 

 scutellum and metanotum are much reduced ; the curved line on the median segment 

 is absent; the abdominal segments 2-6 are broadly black at the base; the last 

 segment is black, with two small yellow marks, punctured at the base, the apex almost 

 impunctate ; the second ventral segment has an elongate tubercle ; the antennal joints 

 are cylindrical, somewhat dilated beneath ; and the anterior tarsi are not dilated. 



A variable species. In some examples the yellow marks on the scutellum and 

 median segment, and also the yellow band on the first abdominal segment, are oblite- 

 rated ; the yellow band on the other segments is much narrowed ; and the tibiae are 

 more or less lined with black behind. 



I was somewhat in doubt as to our Mexican specimens being really B. burmeisteri ; 

 because Handlirsch states that his species agrees with B. fodiens in the form of the 

 sixth dorsal plate (that of B. fodiens being figured by him), while it is very different in 

 our examples. However, Herr Handlirsch has kindly informed me that they are 

 undoubtedly referable to B. burmeisteri.
