218 [September, 



noted that H. telescopicus was found flying in bright sunshine in open 

 glades of jungle near felled timber. Flight sustained, three or four 

 found frequently pla^^'ng together like common flies in a room, or like 

 JEpheineridoe. 



H. Maclachlani, sp. nov. 



Dull, somewhat stroiiijly pilose on head, pronotum, h^gs and lateral margin of 

 abdomen. Posterior lobe of head subrotundate, a trifle transverse, not suleate, long- 

 pilose, a little callose basally beneath. Eyes and ocelli prominent. Rostrum about 

 two-thirds longer than head, first segment subannuliform, second about three times 

 as long as the first, tliird two and a half times as long as second, and nearly twice as 

 long as fourth. Antennae twice as long as head, sparsely setose, somewhat slender, 

 first segment stouter than the rest, reaching beyond apex of head ; second segment 

 two and four-fifths as long as the first, one-fifth longer than third, and two-fifths 

 longer than fourth. Anterior lobe of pronotum a little shorter than the intermediate 

 and posterior, which are medianly subequal ; posterior lobe two and three-quarter 

 times as broad as anterior lobe, and four-sevenths broader than intermediate lobe, 

 which is longitudinally impressed (or broadly suicide) ; posterior lobe medianly 

 somewhat obsoletely carinate, lateral margins rounded, diverging towards the base, 

 which is obtuse-angularly emarginate. Anterior legs not very stout, tibiae dilated 

 apically, tarsi with two long unequal claws. Elytral nervures sparingly pilose. 

 Abdomen carinate broadly beneath. Head and pronotum piceous above and beneath, 

 the posterior lobe of the pronotum more pallid. Antenna?, anterior femora, &c., dark 

 fuscous, antennae more or less clouded with pallid ; rest of legs, abdomen above 

 and beneath, fusco-testaceous ; legs not annulate. Elytra cinereohyaline, nervures 

 cinereous ; wing-nervures pallid cinei-eous. 



Length (excl. elytra), 5f mm. ; expanse of elytra, about 8j mm.

Tt is ])ossible that this species may be identical with the very 

 insufficiently described tasmfinicns, Westw., wdiich. however, according 

 to Westwood, is larger, has concolorous antennsp, and the exterior 

 margin of the elytra white at the base. From the Sinhalese teles- 

 copicus (Kirby), the only other species of which T have examined 

 several examples, it differs by its much smaller size. The latter is also 

 much more robust, and the antennre are shorter and thicker, the pos- 

 terior margin of the pronotum is truncate, and the posterior lobe of 

 the head more elongate. In Champion's descriptions of American 

 species it works out near annulipes, Champ., from which it is at once 

 distinguished by the non-annulate legs. H. vioscltatns has a smooth 

 head and is entirely fuscotestaceous. This species and StTd's Brazilian 

 forms are much (comparatively) smaller. H. snl)antarcfieus. Berg, 

 has a differentl}^ formed pronotum and shorter elytra [J forma hrachy- 

 ptera) and differently proportioned antennae.
